James, that does indeed execute properly if it is executed from the server
computer, using local paths (E:\SQLServerData instead of
\\Stonehenge\SQLServerData\). If I try to run it from my laptop it gives
errors:
Processed 192 pages for database 'IRGeneric', file 'IRGeneric' on file 2.
Processed 1 pages for database 'IRGeneric', file 'IRGeneric_log' on file 2.

AFAIK the \\ directories are read / write. Perhaps SQL Server will not
perform some operations to network paths? If I run it from my Server
machine substituting e:\SQLServerData\ it runs.
If I try to execute the SP from my laptop using E:\ (which exists on the
server but not on my laptop) it throws an error:
Processed 192 pages for database 'IRGeneric', file 'IRGeneric' on file 4.
Processed 1 pages for database 'IRGeneric', file 'IRGeneric_log' on file 4.
BACKUP DATABASE successfully processed 193 pages in 0.024 seconds (65.877

The tail of the log for the database "IRTest" has not been backed up. Use
BACKUP LOG WITH NORECOVERY to backup the log if it contains work you do not
want to lose. Use the WITH REPLACE or WITH STOPAT clause of the RESTORE
statement to just overwrite the contents of the log.
Msg 3013, Level 16, State 1, Procedure usp_CopyDatabase, Line 33
RESTORE DATABASE is terminating abnormally.
I suspect that this is a "something fails the second time" kind of thing
since it is throwing the same error when executed again directly on the
server.
I tried the following:
RESTORE DATABASE @strDBNameTo
FROM DISK = @FileName
WITH MOVE @strDBNameData TO @MDFName,
MOVE @strDBNameLog TO @NDFName
WITH REPLACE
But it now gives the infamous "incorrect syntax near WITH" error.
RESTORE DATABASE @strDBNameTo
FROM DISK = @FileName
WITH REPLACE
WITH MOVE @strDBNameData TO @MDFName,
MOVE @strDBNameLog TO @NDFName
Gives me the same thing.
GETTING CLOSE!! 8-)

John:
It is failing because the stored procedure makes certain assumptions about
the logical and physical names of the mdf and ldf files, which is seems do
not apply to your test database. It assumes the data file is called
IRGeneric_Data.mdf and the log file is called IRGeneric_Log.ndf. According
to the output, it looks as though your files are called IRGeneric.mdf and
IRGeneric_Log.ndf.
If you change the line:
Select @strDBNameData = @strDBNameFrom + '_Data'
To
Select @strDBNameData = @strDBNameFrom
then it should work.

James,
I created the SP, and executed it from the query window.
execute usp_CopyDatabase "IRGeneric", "IRTest",
"\\Stonehenge\SQLServerData\"
And received the following:
Processed 192 pages for database 'IRGeneric', file 'IRGeneric' on file 1.
Processed 2 pages for database 'IRGeneric', file 'IRGeneric_log' on file 1.
BACKUP DATABASE successfully processed 194 pages in 0.061 seconds (25.935
MB/sec).
Msg 3234, Level 16, State 2, Procedure usp_CopyDatabase, Line 30 Logical
file 'IRGeneric_Data' is not part of database 'IRTest'. Use RESTORE
FILELISTONLY to list the logical file names.
Msg 3013, Level 16, State 1, Procedure usp_CopyDatabase, Line 30 RESTORE
DATABASE is terminating abnormally.
It certainly sounds like the backup happened, and if I go to the
\\Stonehenge\SQLServerData\ directory there is a file IRGeneric.BAK.
It would seem that restoring the backup file to a different file name is
causing an issue?
One obvious question, how do I compute the line number referenced? Is that
"line 30 from the top of the file" or line 30 from the procedure
declaration? My uneducated guess is from the function declaration line.
After that, any clue on what the failure is actually saying.
Thanks,
John W. Colby

John:
Try this:

RESTORE FILELISTONLY FROM DISK = @FileName
Select @FileName = @strDBDir + @strDBNameFrom + '.bak'

RESTORE DATABASE @strDBNameTo

WITH MOVE @strDBNameData TO @MDFName,

It should do exactly what you need.

Thanks Elizabeth and Gustav.
I tried to get it working using passed in parameters, but promptly got
bogged down in the ever helpful "error near ." error messages.
I need a "FromDbName", a "ToDbName", and a "DbLocationPath" parameter. Just
to show the kinds of issues that more advanced users never even think about
anymore, but which stop me cold...
I created these parameters in a stored procedure, copied the code in and
started replacing the various pieces with @ParamThis and @paramThat. I
immediately got the one and only error message that SQL Server knows "error
near @".
I got out BOL "the ever helpful.." ... Oh, different rant.
I immediately commented out the code pasted in to the SP template and voila,
it "ran". Uncommented just the first line and get "error near +"
ALTER PROCEDURE [dbo].[usp_CopyDatabase]
-- Add the parameters for the stored procedure here
@strDBNameFrom varchar(100),
@strDBNameTo varchar(100),
@strDBDir varchar(255)
AS
BEGIN
-- SET NOCOUNT ON added to prevent extra result sets from
-- interfering with SELECT statements.
SET NOCOUNT ON;
-- Insert statements for procedure here --BACKUP DATABASE @strDBNameFrom
-- TO DISK = @strDBDir + @strDBNameFrom + '.bak'
--RESTORE FILELISTONLY
-- FROM DISK = @strDBDir + @strDBNameFrom + '.bak'
--RESTORE DATABASE @strDBNameTo
-- FROM DISK = @strDBDir + @strDBNameFrom + '.bak'
-- WITH MOVE strDBNameFrom + '_Data' TO @strDBDir + @strDBNameTo +
'.mdf',
-- MOVE strDBNameFrom + '_Log' TO @strDBDir + @strDBNameTo + '.ldf'
END
My uneducated guess is that as soon as I start actually trying to run this
thing, the parameters have nothing in them so they will not run. But...
Running it is the only way to "SAVE" the changes right? So I am kind of
stuck. So do I have to make my parameters have default values just so the
changes to the code will save? Or is it even that?
I can't imagine why I would get frustrated when I get the ever helpful
"error near +".

Subject: Re: [dba-SQLServer] Copy a database using a store procedureor
function
Hi Elizabeth - and John
The gun smoke distracted me so much from the original question that I had
lost the request of John - to be able to perform this parameterized from
code.
But it seems like your suggestion could be the key of a solution. I found a
minor error ('AdventureWorks_Data' should read just 'AdventureWorks'). With
that corrected I simply moved your code (skipping the GO) into a
pass-through query in Access:
BACKUP DATABASE somedb
TO DISK = 'c:\template2.bak'
RESTORE FILELISTONLY
FROM DISK = 'c:\template2.bak'
RESTORE DATABASE newfromtemplate2
FROM DISK = 'c:\template2.bak'
WITH MOVE 'somedb' TO 'c:\newfromtemplate2.mdf',
MOVE 'somedb_log' TO 'c:\newfromtemplate2.ldf'
Wow! In a few seconds you have a brand new database.
Of course, once a template has been created you can skip the first part with
the backup.
Now, for this to work as to fulfill John's request, you will have to rewrite
the SQL above to reflect the name of the new database but that can be done
with a simple replace of "newfromtemplate2" to the actual new database name
and then execute the query. This John can code with his left hand in Access
and it shouldn't take much to write a small class in VB.net to perform the
same two actions: replace the database name and send the SQL command to the
server.

I haven't used this (being pretty new to this myself), but I'm sure some one
else here can speak to it:
E. Make a copy of a database using BACKUP and RESTORE This example uses both
the BACKUP and RESTORE statements to make a copy of the AdventureWorks
database. The MOVE statement causes the data and log file to be restored to
the specified locations. The RESTORE FILELISTONLY statement is used to
determine the number and names of the files in the database being restored.
The new copy of the database is named TestDB. For more information, see
RESTORE FILELISTONLY (Transact-SQL).
Copy Code
BACKUP DATABASE AdventureWorks
TO DISK = 'C:\AdventureWorks.bak'
RESTORE FILELISTONLY
FROM DISK = 'C:\AdventureWorks.bak'
RESTORE DATABASE TestDB
FROM DISK = 'C:\AdventureWorks.bak'
WITH MOVE 'AdventureWorks_Data' TO 'C:\testdb.mdf',
MOVE 'AdventureWorks_Log' TO 'C:\testdb.ldf'
GO
This is from BOL for SQL Server 2005, which is often amazingly helpful.
HTH,
