[AccessD] ADO question: VB FE to SS7

>From a program point of view, I agree that it does not matter.  But good
programming practices say that you should release your connection to the
server as soon as possible.  And since you have a pretty low connection
rate, I would have to say that I think that you should recreate the object
each time you need it.  The speed penalty to your program should be
imperceptible.  This allows the most efficient use of your SQL server.

Just my $0.02.

I don't think it is really going to matter.  If you don't want to leave the
object loaded, then create and close it each time.  That makes the process
take a wee bit longer.  If you want to leave it open, then do so, that just
keeps a live connection to the database.  Either way, both 'effects' are
minimal, so I wouldn't be concerned either way.

I say this because you mention 200 to 400 a day.  That's a lot less then 1 a
minute.  I wouldn't be concerned about opening and closing it unless you
were talking aobut 20 to 30 a minute (one every 2 or 3 seconds....), because
then the open and close method would be taking up more valuable time, and
you might end up with periods of backlog.

Hi All,

I am working on a VB app that will be used to store telephone call
information to SQL Server 7.
The VB app is monitoring the serial port for incoming data. Once a complete
call record is received that record will be parsed and then added to the
database.
My question is, should I create a static ADODB command object and used it
over and over as needed or should I destroy and recreate the ADODB command
object each time it is needed? What are the pros and cons?

On average, the number of records being added per day, during working hours,
would be around 200 to 400.
I want this application to be running 24/7.

Any suggestions?

Thanks,
Joe R.
