Hi all,
 
 
We have a user that got "locked"  in some process or transaction or  table, excuse the language here,  the former version of the program had a syslocks utility to release anything in that type of situation,   it turns out that utlity was removed and the only thing i could find to point me in the right direction was a querey i found online,
 
SELECT * FROM master.dbo.syslockinfo 
 
here is what it output  but i can really make heads or tails
I know its not a lot to go on, but any pointers thoughts would be appreciated
 
 
column headers are 
rsc_bin,rsc_valblk,rsc_dbid,rsc_indid,rsc_objid,rsc_type,_rsc_flag,req_mode,req_statu,req_refcnt,req_cryrefecnt,req_lifetime,req_spid,req_ecid,req_ownertype,req_transactionid,req_transactionUOW

Subject: [dba-SQLServer] Stored procedure parameters
Message-ID: <4E3C6262.5090002@colbyconsulting.com>

I have a form which I want to open and display a single record in.  I am building a SP to pull just 
that one record but I have two different parameters that I can use to find the record, the PKID (an 
Integer) and a string "opus number".  IOW I will pass one or the other but not both.

Should I build a single SP with two params and just do a test internal to the SP to determine which 
param has a value in it?  Should I build two different SPs?  Should I use some third strategy?

You can do it your way with two parameters:

CREATE PROCEDURE stpJCsSproc (@PKID INT NULL, @Opus NVARCHAR(10)) AS
IF ISNULL(PKID,0) <> 0
   SELECT * FROM BLAH WHERE PKID = @PKID
ELSE
   SELECT * FROM BLEH WHERE Opus = @Opus


or you can do something like this

CREATE PROCEDURE stpJCsSproc (@IntMode INT, @Opus NVARCHAR(20)) AS
IF @IntMode = 1 --By PKID
   SELECT * FROM BLAH WHERE PKID = CAST(@Opus AS INT)
ELSE IF @intMode = 2 --By Opus
   SELECT * FROM BLEH WHERE Opus = @Opus
--any future more can be added here without changing input parameters
--ELSE IF @intMode = 3 --By Composer
--   SELECT * FROM tblMusic WHERE Composer = @Opus

Is this a correct sql statement to delete the first 5 rows (oldest dates) of
a recordset for Access 2002? I'm new to SQL.

strSQL1 = "DELETE FROM rs WHERE TOP 5,  player=1 ORDER BY playdate ASC;"
DoCmd.RunSQL strSQL1

Hi Wil,

Others will probably jump in but I think you could end up deleting more
than 5 rows. If there are multiple 5th top rows ie with the same date.
In SQL Server you would do something like...
DELETE FROM [tableName]
WHERE ID IN (  SELECT TOP 5 ID FROM [tableName] WHERE [tableName].
player = 1 ORDER BY playdate ASC )

I see you are using a Access recordset. This won't work. I don't think
you can run a query against a recordset. 

Why not just open the recordset sorted and loop 5 times deleting as you
go? I'm not sure but I seem to recall you don't need to movenext if you
are deleteing.

Cheers

Michael M

Hello Michael and Wil,

Wil, thanks for that, I did not know that you could use TOP n in the where
clause, I only use it when I select.

Michael, thanks for highlighting the potential additional records, I am
looking forward to playing with TOP in where clauses,

Mark

Like this?

'select rs and order by date
strsql1 = "SELECT * FROM rs WHERE player=1 ORDER BY playdate ASC
DoCmd.runsql strsql1
rs.movefirst

for n = 1 to 5
  rs.delete
next n

rs.update

Woops! I just read that a snapshot RS cannot be edited. I don't want to
modify the underlying table so I used snapshot rs. Is there another way to
play with the data in the table without modifying the underlying table?

Ok, the plot thickens :-)
So you only want to remove the rows from the recordset not the
underlying data?
To disconnect the ADO  recordset from the database you set the
connection to nothing, after loading the recordset.
You will have to trial and error to see what type of recordset you need,
snapshot won't work as you have discovered.
I havn't used access as a FE for years so others might want to chip
in???

Cheers

Subject: [dba-SQLServer] Question Concerning Microsoft SQL Server 2008 R2
	Prerequisites
Message-ID: <000501cc5bf9$8f8b30f0$aea192d0$@net>

This is my first post to the dba-sqlserver list, (and I am a total "noobie"
to SQL Server), so I hope no one will consider this a dumb question.

I have decided to study for and pursue certification in Microsoft's SQL
Server 2008 R2 database platform.  My previous work experience was primarily
in Access development with some Visual Basic coding.  I have virtually no
SQL Server experience.  Thanks to a recommendation from Susan Harkins, I
plan to download and install SQL Server 2008 R2 (the free "Express" edition)
and learn all I can using that tool along with books and study guides.  My
initial plan is to study for (and pass) exam 70-432, "TS: Microsoft SQL
Server 2008, Implementation and Maintenance," followed by exams 70-433 and
70-448.  (After obtaining those three certifications, hopefully I can find a
job because poverty sucks!)

One of the first resources I have discovered is Microsoft's online eBook
"Introducing Microsoft SQL Server 2008 R2" by Ross Mistry and Stacia Misner.
In chapter 1 of Ross and Stacia's book, (i.e. "SQL Server 2008 R2 Editions
and Enhancements"), under subsection "SQL Server 2008 R2 Enhancements for
DBAs," the following quotation appears in the final sentence of the second
paragraph on page 3:

<begin quotation>

Enhancements to scalability and performance, high availability, enterprise
security, enterprise manageability, data warehousing, reporting,
self-service BI, collaboration, and tight integration with Microsoft Visual
Studio 2010, Microsoft SharePoint 2010, and SQL Server PowerPivot for
SharePoint make it the best database platform available.

<end quotation>

My question concerns the three Microsoft products mentioned in that
sentence, specifically "Microsoft Visual Studio 2010, Microsoft SharePoint
2010, and SQL Server PowerPivot for SharePoint."  Is knowledge and
experience with these three products taken for granted - an assumed
prerequisite - prior to pursuing a SQL Server certification?  (I have no
knowledge or experience with any of these three products - I don't even know
what SharePoint is - or what SharePoint does.)  As far as PowerPivot is
concerned, I think that has something to do with Excel spreadsheets.  My
prior experience with Excel was limited to converting (and copying over)
spreadsheet data to Access tables.  Is a detailed knowledge of these three
Microsoft technologies required (or assumed) as a prerequisite to pursuing a
SQL Server certification?

TIA.  (I suspect this is going to be the first of many questions.)

Hi Alan,

Nice to see you over on this list.

SQL Server is a Database Management System.  It is generally used as the back-end to 
some sort of front end application.  You can use anything you like for the front end.  A 
number here and on the VB List use Visual Studio but it is not the only thing to use ( I 
stopped using VS years ago).  

Sharepoint is used by a small minority of SQL users.
Forget about Excel, PowerPivot has nothing to do with  that application.

At this stage, you would probably be best off sticking to Access as the front end with ODBC 
linked tables and PassThrough Queries to stored procedures in SQL Server.   You get your 
head around the fundamentals of tables, triggers, SQL and stored procedures, how user 
permissions  work, how backups work, how import and export works.  They are the key 
components of managing SQL Server.   Then you can look at other front ends if required.   

Many DBAs (Database Administrators) don't get involved in front end application 
development at all - they just manage the back end and leave it up to others to use the data 
in real-world applications.

Stuart:

Thanks.  This is encouraging.  I vaguely remember SQL pass-through queries,
ODBC, and linked tables from my Access days.  I even recall playing around a
bit with ADO.  In my last software job, we had an Access application that
was being converted to a SQL Server back end, but I left before the
conversion was completed.  That was over five years ago.  I did get a small
amount of experience with SQL Server.  (I recall a GUI interface labeled
"Enterprise Manager" that resembled a tree-like structure with a lot of
lower-level branches - or something similar to that.)

This may not be as difficult as I originally thought.  From what you're
describing, combined with my past experience, I should be able to pick up
most of the major implementation and maintenance topics in fairly short
order.  According to this:

   http://tinyurl.com/27f4fzt

blog posting by Buck Woody, there are over 40 major study areas covered in
the 70-432 exam.  At first glance, most of the topics - and the links to
their corresponding MSDN articles - don't look familiar, but surely I've
been exposed to some of this before.  With determined effort, (and a little
help from my friends), I believe I can master this material and ace the
exam.  (Thank goodness I don't have to become a SharePoint and Visual Studio
expert in order to pass the exam.  That's a relief!)

Five years ago I turned downed an offer of a Database Administrator job in
Iraq.  I was worried that I might not be qualified, but I was even more
worried about being surrounded by terrorists!  With perfect 20/20 hindsight,
I probably should have taken that job - whether I was qualified or not - and
"grown" into it once I was over there.  Once I've passed 70-432 and obtained
my (first) certification, I feel fairly confident that I'll find a DBA job
somewhere - even if it's on a remote island in the middle of the South
Pacific.  (It will be nice to work someplace where you can walk to work and
you don't need a car.)

Thanks again for the good news.  I'm now even more motivated to study my
butt off.

Hi Alan,

Nice to see you over on this list.

SQL Server is a Database Management System.  It is generally used as the
back-end to 
some sort of front end application.  You can use anything you like for the
front end.  A 
number here and on the VB List use Visual Studio but it is not the only
thing to use ( I 
stopped using VS years ago).  

Sharepoint is used by a small minority of SQL users.
Forget about Excel, PowerPivot has nothing to do with  that application.

At this stage, you would probably be best off sticking to Access as the
front end with ODBC 
linked tables and PassThrough Queries to stored procedures in SQL Server.
You get your 
head around the fundamentals of tables, triggers, SQL and stored procedures,
how user 
permissions  work, how backups work, how import and export works.  They are
the key 
components of managing SQL Server.   Then you can look at other front ends
if required.   

Many DBAs (Database Administrators) don't get involved in front end
application 
development at all - they just manage the back end and leave it up to others
to use the data 
in real-world applications.

Based on the link, that exam is purely DB Administration stuff..  

After a bit of research, I'd suggest you need to work on 70-433 concurrently.  See:

Hmmmm, it is my understanding that Powerpivot is an add in for Excel 2010.....

http://www.powerpivot.com/

I've seen demos of it and it is really a powerful tool for analyzing
Data Warehouse type data - almost gives end users the ability to
create their own data marts.

But it would be outside of a SQL Server DBA kind of tool.

I should have been more specific.

There are two PowerPivots components:  PowerPivot for Excel and  PowerPivot for 
Sharepoint.  

I was referring to the latter which Alan's asked about.

I plunked down a little over $50 today and bought a copy of "murach's SQL
Server 2008 for developers" book.  This is a 750 page tome (including a
couple of Appendixes) that include instructions for downloading SQL Server
Express (with Tools), the Management Studio, Books Online and two sample
databases.  There are 22 chapters in this book with heavy emphasis on T-SQL,
so I think this will be a very good study resource and prep guide for
passing the SQL Server Developer's exam - (i.e. 70-433).

 

In scanning this book prior to purchase, I noticed that each chapter ends
with a section of "Terms" that were covered in the chapter.  For instance, I
have seen frequent references to the term "instance" in Books Online, but
I've never been sure exactly what "instance" (or an "instance") means.
Based on what I'm reading in this book, an entity is a class of objects (for
instance "cars") and a particular car would be a member of that class, so if
a table represents a class of objects, then a row within the table would be
an instance.  (An instance is not a copy - it's a member of a class.)
That's where I was getting confused - I thought "instance" was a copy, but
apparently it's not.

 

What has me confused now is another section of the book where I read that
you can have "two instances" of SQL Server running simultaneously on the
same machine.  If I recalled correctly, that would seem to imply that an
"instance" is a copy!  (Maybe what that sentence was implying is that you
can have SQL Server running two different [application] databases off the
same SQL Server database engine simultaneously - so the two separate
databases are the "instances" - while the [installed] SQL Server database
engine is the entity.)

 

Hopefully this book will help me unravel all the terminology and clear out
the cobwebs.

Two instances of SQL Server, means that you have  two separate installations od the 
database engine running concurrently on the same machine 

The first time you instal SQL Server on a machine, it is automatically installed as  the "Default 
Instance".   You can then do a complete  instal  of SQL Server again, this time as a "Named 
Instance"  where you specify a different name and different port(s) for it to operate on.

The concept was introduces with SQL Server 2000.

My understanding is that the instances are actual services, the SQL Server service is running twice. 
  Any instance can be running many different databases simultaneously.

But what do I know? ;)

Stuart:

Thanks for the link.  I think I understand why you would have named
instances on the same machine.  You might have one named instance for the
engineering department of a very large company and a second named instance
for the accounting department - with each department having their own
databases and applications - and their own copy of SQL Server dedicated
solely to their instance with both instances running on the same computer.
(That computer better have a lot of horsepower - especially if you have

Two instances of SQL Server, means that you have  two separate installations
od the 
database engine running concurrently on the same machine 

The first time you instal SQL Server on a machine, it is automatically
installed as  the "Default 
Instance".   You can then do a complete  instal  of SQL Server again, this
time as a "Named 
Instance"  where you specify a different name and different port(s) for it
to operate on.

The concept was introduces with SQL Server 2000.

SQL Server has properties for assigning physical cores to it as well as amounts of memory.  I have a 
16 core server with 32 gigs of memory.  If I run two instances I can assign one SQL Server instance 
4 cores and 8 gigs of memory, another instance 8 cores and 20 gigs of memory.  All cores and memory 
not assigned are left for the OS.

John:

I'm not sure exactly how triggers would apply to your specific situation,
(i.e. exactly how you would go about coding a solution to your problem), but
Francisco may be on to something.  In "Section 4 - Advanced SQL skills" on
pages 470 and 471 of "murach's SQL Server 2008 for developers" book, the
author has a section entitled "How to use triggers to enforce data
consistency".  The problem (and solution) he presents may not be precisely
applicable to the problem you're describing, but you may be able to get a
good idea of how to go about solving your problem from reading those pages.

I'm in the early stages of trying to figure out and "learn" SQL Server.
>From what I've read so far, triggers seem to be designed to ensure data
validation (data consistency) and maintain relationships between tables.
What you're trying to do seems related to this, so maybe a stored procedure
that includes a trigger will solve your problem.

This is great - I'm now a SQL Server consultant!   :-)))

Hi John

Just add a new constraint, name it properly, and add an expression that states the rule you explain, like: 

Not ([ParentType] Is Null And [ProfessionalType] Is Null)

And mark: Enforce for INSERTs and UPDATEs

Besdies ensuring data consistency, triggers are often used for maintaining
an audit trail. On an insert it doesn't make much sense, but on update and
delete it does (you can write the old row to a table before doing the actual
update, or write the old row to a table before doing the delete). IIRC,
Susan and I wrote about that some time ago in TechRepublic.

If I have a clustered index on my PK (autoincrement int) and that is used in all indexes without

unique?  Do I need to check the unique box when creating the index?

Or does "unique" only count on the actual fields specified in the index?

It took me the better part of 4-5 hours, (including installation of all the
"prerequisite" software along with several service pack upgrades after the
installation), but I managed to successfully download and install the SQL
Server 2008 R2 "Express" edition (with Books Online) to my Windows XP SP3
notebook computer.  It took a bit of head scratching figuring it all out,
(there's a bunch of "stuff" about Windows authentication that I need to
learn), but I finally got it all to work.

I'll download and attach the Accounts Payable sample database that goes with
my Murach SQL Server developer's book tomorrow.  Then I'll be on my way to
becoming a SQL Server expert.  I aspire to be half-to-three-quarters as
great as Rocky, John Colby, Stuart McLachlan, Gustav Brock, Francisco Tapia,
Susan Harkins, Gary Kjos, and Arthur Fuller.  (Did I leave anybody out?)

If I can get as smart as you guys (and Susan) at my advanced age, that will
be an accomplishment!

I suppose I should have started working on this a year ago - when I still
had some money - but I was convinced that I was a 55-year-old version of
Doyle Brunson on my way to earning vast riches at the poker table.  Live and
learn I suppose .

{rest of code continues}

However, if I change the last line to
GROUP BY DATEPART(week, dbo.tblRoll.KnitDate)) AS spKnit ON WeekNo = 
spKnit.WeekNum
it saves and works.

Why doesn't it accept the table part of the WeekNo field?

Great!

There are actually a lot of statistical analysis functions within
Analysis Services which is part of the full version of SQL Server -
not sure if it's in Express - that you might be able to use to analyze
your poker game too. ;-)

Keep up the good work Alan. You are gaining momentum.

BI + Poker = Broke :) The most intelligent poker play is Step Away From the
Table. If you must gamble, try speed chess + the doubling cube (borrowed
from backgammon), an innovation introduced by my friend and
backgammon-mentor Vladimir Dobrich.

i'm not sure, but i've always used an alias when I join my temp tables
including variable tables, so my change would read

FROM @ttmpWeeks AS tWeeks

then your ON statment can read tWeeks.WeekNo = join clause

Hi David,

what is the difference between Temp table and using a variable tables.  I
never used such an exotic thing ?

thanks

Mark

Variable tables are generally tables in memory and are meant to be light so
that they can survive in memory.  A major advantage is you can convert comma
delimited lists to variable tables (generally a small-ish table) and have
all the benefits of a normal table but in RAM.  Temp tables if small will
remain in memory, but if the server is busy with other major tasks that
demand memory, your temp table will be written to disk.  In general a
placeholder is always created, but your data may just be in RAM vs on disk,
my recommendation for people using variable tables or temp tables is that if
you're going to be hauling a lot of data (or potentially a lot of data) then
you should architect your solution with temp tables, otherwise for smaller
datasets a variable table is a great performance option.

Message-ID: <CAGXtTCjM+JqKpDXLw3cDtsLCuX1KF0=UH0rqdqZ8+WBhWvBg6A@mail.gmail.com>

Hello All,

I recently set up a mirror of a db over the Lan and was shocked at how easy
it is to do.

I wonder whether it is feasible to run a mirror over a DSL line.  Would it
be terrible performance - is it usually only used over LAN speeds?

I know I can just try it, but just in case you have any advice it will be
welcome,

In case you do not know,the steps are

1) switch recovery mode to Full
2) backup full db
3) restore full db to another server but set restore mode to "Restore with
no recovery".  It is the second radio button on same pane where you click
"Verify backup".
4) On the properties tab of your main db, go to mirroring, use the wizard to
click through about four steps where you set the authentication and bingo
you have a mirrored server.
note:  I skipped the option of a witness server.

Once you do that,  you have a red hot backup of your main db at all times.

thanks

Mark

Hello Francisco,

Thank you for your time to respond.

That is extremely interesting and happens to coincide with some sql that I
am working on currently.

I have a few sprocs that search through all tables, all columns, all schemas
for some text and uses a temp table for temp storage on each iteration.

I did not yet see how to avoid using a cursor, so the temp table is used
each time I loop.

Currently the routine takes 4  hours and I had to return my intel i7 to
standard settings because it was reaching 90 degrees when all cores were
maxed out!

I can do some timings so when I do, I will post the results.

thanks again,
Mark

I wrote up a script that leverages another developer's solution, I co-wrote
this article with Susan Harkins...

http://www.devx.com/dbzone/Article/42340/1954?pf=true

maybe you can extend or improve on what i've done to help leverage, I'm not
sure if the link will prompt you to have a free login account (i may have my
browser cookies saved, if so I'll re-post the script here)

I think you can definitely run in this scenario, but there are some things
you want to think about...performance will be greatly affected because in
the past when I worked with db mirroring, users had to wait until the log
shipping completed on the destination database.  I remember that this was
one of the big performance features that was being worked on for 2008, but I
never returned to see if this was actually fixed, the demo's of course made
it seem like you could have db mirroring across continents w/o even the
thought of latency in the mix.

report back your results, I am very interested.

Hi all,
 
 
We have a user that got "locked"  in some process or transaction or  table, excuse the language here,  the former version of the program had a syslocks utility to release anything in that type of situation,   it turns out that utlity was removed and the only thing i could find to point me in the right direction was a querey i found online,
 
SELECT * FROM master.dbo.syslockinfo 
 
here is what it output  but i can really make heads or tails
I know its not a lot to go on, but any pointers thoughts would be appreciated

Subject: [dba-SQLServer] Stored procedure parameters
Message-ID: <4E3C6262.5090002@colbyconsulting.com>

I have a form which I want to open and display a single record in.  I am building a SP to pull just 
that one record but I have two different parameters that I can use to find the record, the PKID (an 
Integer) and a string "opus number".  IOW I will pass one or the other but not both.

Should I build a single SP with two params and just do a test internal to the SP to determine which 
param has a value in it?  Should I build two different SPs?  Should I use some third strategy?

You can do it your way with two parameters:

CREATE PROCEDURE stpJCsSproc (@PKID INT NULL, @Opus NVARCHAR(10)) AS
IF ISNULL(PKID,0) <> 0
   SELECT * FROM BLAH WHERE PKID = @PKID
ELSE
   SELECT * FROM BLEH WHERE Opus = @Opus


or you can do something like this

CREATE PROCEDURE stpJCsSproc (@IntMode INT, @Opus NVARCHAR(20)) AS
IF @IntMode = 1 --By PKID
   SELECT * FROM BLAH WHERE PKID = CAST(@Opus AS INT)
ELSE IF @intMode = 2 --By Opus
   SELECT * FROM BLEH WHERE Opus = @Opus
--any future more can be added here without changing input parameters
--ELSE IF @intMode = 3 --By Composer
--   SELECT * FROM tblMusic WHERE Composer = @Opus

Is this a correct sql statement to delete the first 5 rows (oldest dates) of
a recordset for Access 2002? I'm new to SQL.

strSQL1 = "DELETE FROM rs WHERE TOP 5,  player=1 ORDER BY playdate ASC;"
DoCmd.RunSQL strSQL1

Hi Wil,

Others will probably jump in but I think you could end up deleting more
than 5 rows. If there are multiple 5th top rows ie with the same date.
In SQL Server you would do something like...
DELETE FROM [tableName]
WHERE ID IN (  SELECT TOP 5 ID FROM [tableName] WHERE [tableName].
player = 1 ORDER BY playdate ASC )

I see you are using a Access recordset. This won't work. I don't think
you can run a query against a recordset. 

Why not just open the recordset sorted and loop 5 times deleting as you
go? I'm not sure but I seem to recall you don't need to movenext if you
are deleteing.

Cheers

Michael M

Hello Michael and Wil,

Wil, thanks for that, I did not know that you could use TOP n in the where
clause, I only use it when I select.

Michael, thanks for highlighting the potential additional records, I am
looking forward to playing with TOP in where clauses,

Mark

Like this?

'select rs and order by date
strsql1 = "SELECT * FROM rs WHERE player=1 ORDER BY playdate ASC
DoCmd.runsql strsql1
rs.movefirst

for n = 1 to 5
  rs.delete
next n

rs.update

Woops! I just read that a snapshot RS cannot be edited. I don't want to
modify the underlying table so I used snapshot rs. Is there another way to
play with the data in the table without modifying the underlying table?

Ok, the plot thickens :-)
So you only want to remove the rows from the recordset not the
underlying data?
To disconnect the ADO  recordset from the database you set the
connection to nothing, after loading the recordset.
You will have to trial and error to see what type of recordset you need,
snapshot won't work as you have discovered.
I havn't used access as a FE for years so others might want to chip
in???

Cheers

Subject: [dba-SQLServer] Question Concerning Microsoft SQL Server 2008 R2
	Prerequisites
Message-ID: <000501cc5bf9$8f8b30f0$aea192d0$@net>

This is my first post to the dba-sqlserver list, (and I am a total "noobie"
to SQL Server), so I hope no one will consider this a dumb question.

I have decided to study for and pursue certification in Microsoft's SQL
Server 2008 R2 database platform.  My previous work experience was primarily
in Access development with some Visual Basic coding.  I have virtually no
SQL Server experience.  Thanks to a recommendation from Susan Harkins, I
plan to download and install SQL Server 2008 R2 (the free "Express" edition)
and learn all I can using that tool along with books and study guides.  My
initial plan is to study for (and pass) exam 70-432, "TS: Microsoft SQL
Server 2008, Implementation and Maintenance," followed by exams 70-433 and
70-448.  (After obtaining those three certifications, hopefully I can find a
job because poverty sucks!)

One of the first resources I have discovered is Microsoft's online eBook
"Introducing Microsoft SQL Server 2008 R2" by Ross Mistry and Stacia Misner.
In chapter 1 of Ross and Stacia's book, (i.e. "SQL Server 2008 R2 Editions
and Enhancements"), under subsection "SQL Server 2008 R2 Enhancements for
DBAs," the following quotation appears in the final sentence of the second
paragraph on page 3:

<begin quotation>

Enhancements to scalability and performance, high availability, enterprise
security, enterprise manageability, data warehousing, reporting,
self-service BI, collaboration, and tight integration with Microsoft Visual
Studio 2010, Microsoft SharePoint 2010, and SQL Server PowerPivot for
SharePoint make it the best database platform available.

<end quotation>

My question concerns the three Microsoft products mentioned in that
sentence, specifically "Microsoft Visual Studio 2010, Microsoft SharePoint
2010, and SQL Server PowerPivot for SharePoint."  Is knowledge and
experience with these three products taken for granted - an assumed
prerequisite - prior to pursuing a SQL Server certification?  (I have no
knowledge or experience with any of these three products - I don't even know
what SharePoint is - or what SharePoint does.)  As far as PowerPivot is
concerned, I think that has something to do with Excel spreadsheets.  My
prior experience with Excel was limited to converting (and copying over)
spreadsheet data to Access tables.  Is a detailed knowledge of these three
Microsoft technologies required (or assumed) as a prerequisite to pursuing a
SQL Server certification?

TIA.  (I suspect this is going to be the first of many questions.)

Hi Alan,

Nice to see you over on this list.

SQL Server is a Database Management System.  It is generally used as the back-end to 
some sort of front end application.  You can use anything you like for the front end.  A 
number here and on the VB List use Visual Studio but it is not the only thing to use ( I 
stopped using VS years ago).  

Sharepoint is used by a small minority of SQL users.
Forget about Excel, PowerPivot has nothing to do with  that application.

At this stage, you would probably be best off sticking to Access as the front end with ODBC 
linked tables and PassThrough Queries to stored procedures in SQL Server.   You get your 
head around the fundamentals of tables, triggers, SQL and stored procedures, how user 
permissions  work, how backups work, how import and export works.  They are the key 
components of managing SQL Server.   Then you can look at other front ends if required.   

Many DBAs (Database Administrators) don't get involved in front end application 
development at all - they just manage the back end and leave it up to others to use the data 
in real-world applications.

Stuart:

Thanks.  This is encouraging.  I vaguely remember SQL pass-through queries,
ODBC, and linked tables from my Access days.  I even recall playing around a
bit with ADO.  In my last software job, we had an Access application that
was being converted to a SQL Server back end, but I left before the
conversion was completed.  That was over five years ago.  I did get a small
amount of experience with SQL Server.  (I recall a GUI interface labeled
"Enterprise Manager" that resembled a tree-like structure with a lot of
lower-level branches - or something similar to that.)

This may not be as difficult as I originally thought.  From what you're
describing, combined with my past experience, I should be able to pick up
most of the major implementation and maintenance topics in fairly short
order.  According to this:

   http://tinyurl.com/27f4fzt

blog posting by Buck Woody, there are over 40 major study areas covered in
the 70-432 exam.  At first glance, most of the topics - and the links to
their corresponding MSDN articles - don't look familiar, but surely I've
been exposed to some of this before.  With determined effort, (and a little
help from my friends), I believe I can master this material and ace the
exam.  (Thank goodness I don't have to become a SharePoint and Visual Studio
expert in order to pass the exam.  That's a relief!)

Five years ago I turned downed an offer of a Database Administrator job in
Iraq.  I was worried that I might not be qualified, but I was even more
worried about being surrounded by terrorists!  With perfect 20/20 hindsight,
I probably should have taken that job - whether I was qualified or not - and
"grown" into it once I was over there.  Once I've passed 70-432 and obtained
my (first) certification, I feel fairly confident that I'll find a DBA job
somewhere - even if it's on a remote island in the middle of the South
Pacific.  (It will be nice to work someplace where you can walk to work and
you don't need a car.)

Thanks again for the good news.  I'm now even more motivated to study my
butt off.

Alan C. Lawhon

Based on the link, that exam is purely DB Administration stuff..  

After a bit of research, I'd suggest you need to work on 70-433 concurrently.  See:

Hmmmm, it is my understanding that Powerpivot is an add in for Excel 2010.....

http://www.powerpivot.com/

I've seen demos of it and it is really a powerful tool for analyzing
Data Warehouse type data - almost gives end users the ability to
create their own data marts.

But it would be outside of a SQL Server DBA kind of tool.

I should have been more specific.

There are two PowerPivots components:  PowerPivot for Excel and  PowerPivot for 
Sharepoint.  

I was referring to the latter which Alan's asked about.

Subject: [dba-SQLServer] SQL Server Book
Message-ID: <000f01cc5ee5$b7215b00$25641100$@net>

I plunked down a little over $50 today and bought a copy of "murach's SQL
Server 2008 for developers" book.  This is a 750 page tome (including a
couple of Appendixes) that include instructions for downloading SQL Server
Express (with Tools), the Management Studio, Books Online and two sample
databases.  There are 22 chapters in this book with heavy emphasis on T-SQL,
so I think this will be a very good study resource and prep guide for
passing the SQL Server Developer's exam - (i.e. 70-433).

 

In scanning this book prior to purchase, I noticed that each chapter ends
with a section of "Terms" that were covered in the chapter.  For instance, I
have seen frequent references to the term "instance" in Books Online, but
I've never been sure exactly what "instance" (or an "instance") means.
Based on what I'm reading in this book, an entity is a class of objects (for
instance "cars") and a particular car would be a member of that class, so if
a table represents a class of objects, then a row within the table would be
an instance.  (An instance is not a copy - it's a member of a class.)
That's where I was getting confused - I thought "instance" was a copy, but
apparently it's not.

 

What has me confused now is another section of the book where I read that
you can have "two instances" of SQL Server running simultaneously on the
same machine.  If I recalled correctly, that would seem to imply that an
"instance" is a copy!  (Maybe what that sentence was implying is that you
can have SQL Server running two different [application] databases off the
same SQL Server database engine simultaneously - so the two separate
databases are the "instances" - while the [installed] SQL Server database
engine is the entity.)

 

Hopefully this book will help me unravel all the terminology and clear out
the cobwebs.

Two instances of SQL Server, means that you have  two separate installations od the 
database engine running concurrently on the same machine 

The first time you instal SQL Server on a machine, it is automatically installed as  the "Default 
Instance".   You can then do a complete  instal  of SQL Server again, this time as a "Named 
Instance"  where you specify a different name and different port(s) for it to operate on.

The concept was introduces with SQL Server 2000.

My understanding is that the instances are actual services, the SQL Server service is running twice. 
  Any instance can be running many different databases simultaneously.

But what do I know? ;)

Stuart:

Thanks for the link.  I think I understand why you would have named
instances on the same machine.  You might have one named instance for the
engineering department of a very large company and a second named instance
for the accounting department - with each department having their own
databases and applications - and their own copy of SQL Server dedicated
solely to their instance with both instances running on the same computer.
(That computer better have a lot of horsepower - especially if you have
multiple named instances running concurrently with lots of users on each
instance.)

SQL Server has properties for assigning physical cores to it as well as amounts of memory.  I have a 
16 core server with 32 gigs of memory.  If I run two instances I can assign one SQL Server instance 
4 cores and 8 gigs of memory, another instance 8 cores and 20 gigs of memory.  All cores and memory 
not assigned are left for the OS.

Subject: [dba-SQLServer] Enforcing a rule
Message-ID: <4E5AC3F3.2010000@colbyconsulting.com>

I have a table where the client is either a parent type (from a list of parent types) or a 
professional type (from a list of professional types).  I need to enforce that at least one of the 
fields is filled.  IOW both cannot be null, but either one can be null or both can be filled.

How do I do something like that?  I have never used database level constraints other than pk/fk so I 
do not know how to set something like this up.  Any detailed instructions or a pointer to a web page 
would be appreciated.

John:

I'm not sure exactly how triggers would apply to your specific situation,
(i.e. exactly how you would go about coding a solution to your problem), but
Francisco may be on to something.  In "Section 4 - Advanced SQL skills" on
pages 470 and 471 of "murach's SQL Server 2008 for developers" book, the
author has a section entitled "How to use triggers to enforce data
consistency".  The problem (and solution) he presents may not be precisely
applicable to the problem you're describing, but you may be able to get a
good idea of how to go about solving your problem from reading those pages.

I'm in the early stages of trying to figure out and "learn" SQL Server.
>From what I've read so far, triggers seem to be designed to ensure data
validation (data consistency) and maintain relationships between tables.
What you're trying to do seems related to this, so maybe a stored procedure
that includes a trigger will solve your problem.

This is great - I'm now a SQL Server consultant!   :-)))

Hi John

Just add a new constraint, name it properly, and add an expression that states the rule you explain, like: 

Not ([ParentType] Is Null And [ProfessionalType] Is Null)

And mark: Enforce for INSERTs and UPDATEs

Besdies ensuring data consistency, triggers are often used for maintaining
an audit trail. On an insert it doesn't make much sense, but on update and
delete it does (you can write the old row to a table before doing the actual
update, or write the old row to a table before doing the delete). IIRC,
Susan and I wrote about that some time ago in TechRepublic.

If I have a clustered index on my PK (autoincrement int) and that is used in all indexes without 
specififying that it be used (my understanding) does that mean that every index is by definition 
unique?  Do I need to check the unique box when creating the index?

Or does "unique" only count on the actual fields specified in the index?

It took me the better part of 4-5 hours, (including installation of all the
"prerequisite" software along with several service pack upgrades after the
installation), but I managed to successfully download and install the SQL
Server 2008 R2 "Express" edition (with Books Online) to my Windows XP SP3
notebook computer.  It took a bit of head scratching figuring it all out,
(there's a bunch of "stuff" about Windows authentication that I need to
learn), but I finally got it all to work.

I'll download and attach the Accounts Payable sample database that goes with
my Murach SQL Server developer's book tomorrow.  Then I'll be on my way to
becoming a SQL Server expert.  I aspire to be half-to-three-quarters as
great as Rocky, John Colby, Stuart McLachlan, Gustav Brock, Francisco Tapia,
Susan Harkins, Gary Kjos, and Arthur Fuller.  (Did I leave anybody out?)

If I can get as smart as you guys (and Susan) at my advanced age, that will
be an accomplishment!

I suppose I should have started working on this a year ago - when I still
had some money - but I was convinced that I was a 55-year-old version of
Doyle Brunson on my way to earning vast riches at the poker table.  Live and
learn I suppose .

Can someone please explain why this is

ALTER PROCEDURE sprptProductionSummary
         (
                 @txtDate1 varchar(20),

         SET DATEFIRST 1 -- Monday

         DECLARE @ttmpWeeks table (WeekNo tinyint)

         DECLARE @tmpDate as datetime

         SET @tmpDate = @txtDate1

         VALUES (DATEPART(week, @tmpDate))

         SET @tmpDate = DATEADD(week, 1, @tmpDate)

         WHILE @tmpdate < @txtDate2
                 BEGIN
                         INSERT INTO @ttmpWeeks (WeekNo)
                         VALUES (DATEPART(week, @tmpDate))

                         SET @tmpDate = DATEADD(week, 1, @tmpDate)
                 END

         SELECT WeekNo, ISNULL(spKnit.KnittedWeight,0) AS KnittedWeight
         FROM @ttmpWeeks LEFT OUTER JOIN (SELECT DATEPART(week, 
dbo.tblRoll.KnitDate) AS WeekNum, ISNULL(SUM(KnitWeight),0) AS KnittedWeight
                                                 FROM dbo.tblRoll
                                                 WHERE KnitDate 
BETWEEN @txtDate1 AND @txtDate2
                                                 GROUP BY 
DATEPART(week, dbo.tblRoll.KnitDate)) AS spKnit ON @ttmpWeeks.WeekNo 
= spKnit.WeekNum

{rest of code continues}

However, if I change the last line to
GROUP BY DATEPART(week, dbo.tblRoll.KnitDate)) AS spKnit ON WeekNo = 
spKnit.WeekNum
it saves and works.

Why doesn't it accept the table part of the WeekNo field?

Great!

There are actually a lot of statistical analysis functions within
Analysis Services which is part of the full version of SQL Server -
not sure if it's in Express - that you might be able to use to analyze
your poker game too. ;-)

Keep up the good work Alan. You are gaining momentum.

BI + Poker = Broke :) The most intelligent poker play is Step Away From the
Table. If you must gamble, try speed chess + the doubling cube (borrowed
from backgammon), an innovation introduced by my friend and
backgammon-mentor Vladimir Dobrich.

i'm not sure, but i've always used an alias when I join my temp tables
including variable tables, so my change would read

FROM @ttmpWeeks AS tWeeks

then your ON statment can read tWeeks.WeekNo = join clause

Hi David,

what is the difference between Temp table and using a variable tables.  I
never used such an exotic thing ?

thanks

Variable tables are generally tables in memory and are meant to be light so
that they can survive in memory.  A major advantage is you can convert comma
delimited lists to variable tables (generally a small-ish table) and have
all the benefits of a normal table but in RAM.  Temp tables if small will
remain in memory, but if the server is busy with other major tasks that
demand memory, your temp table will be written to disk.  In general a
placeholder is always created, but your data may just be in RAM vs on disk,
my recommendation for people using variable tables or temp tables is that if
you're going to be hauling a lot of data (or potentially a lot of data) then
you should architect your solution with temp tables, otherwise for smaller
datasets a variable table is a great performance option.

Subject: [dba-SQLServer] Mirroring SQL DB's over the internet (as opposed to
	the LAN)
Message-ID: <CAGXtTCjM+JqKpDXLw3cDtsLCuX1KF0=UH0rqdqZ8+WBhWvBg6A@mail.gmail.com>

Hello All,

I recently set up a mirror of a db over the Lan and was shocked at how easy
it is to do.

I wonder whether it is feasible to run a mirror over a DSL line.  Would it
be terrible performance - is it usually only used over LAN speeds?

I know I can just try it, but just in case you have any advice it will be
welcome,

In case you do not know,the steps are

1) switch recovery mode to Full
2) backup full db
3) restore full db to another server but set restore mode to "Restore with
no recovery".  It is the second radio button on same pane where you click
"Verify backup".
4) On the properties tab of your main db, go to mirroring, use the wizard to
click through about four steps where you set the authentication and bingo
you have a mirrored server.
note:  I skipped the option of a witness server.

Once you do that,  you have a red hot backup of your main db at all times.

thanks

Mark

Hello Francisco,

Thank you for your time to respond.

That is extremely interesting and happens to coincide with some sql that I
am working on currently.

I have a few sprocs that search through all tables, all columns, all schemas
for some text and uses a temp table for temp storage on each iteration.

I did not yet see how to avoid using a cursor, so the temp table is used
each time I loop.

Currently the routine takes 4  hours and I had to return my intel i7 to
standard settings because it was reaching 90 degrees when all cores were
maxed out!

I can do some timings so when I do, I will post the results.

thanks again,
Mark

I wrote up a script that leverages another developer's solution, I co-wrote
this article with Susan Harkins...

http://www.devx.com/dbzone/Article/42340/1954?pf=true

maybe you can extend or improve on what i've done to help leverage, I'm not
sure if the link will prompt you to have a free login account (i may have my
browser cookies saved, if so I'll re-post the script here)

Subject: [dba-SQLServer] Mirroring SQL DB's over the internet (as
 opposed to the LAN)

I think you can definitely run in this scenario, but there are some things
you want to think about...performance will be greatly affected because in
the past when I worked with db mirroring, users had to wait until the log
shipping completed on the destination database.  I remember that this was
one of the big performance features that was being worked on for 2008, but I
never returned to see if this was actually fixed, the demo's of course made
it seem like you could have db mirroring across continents w/o even the
thought of latency in the mix.

report back your results, I am very interested.
