I have written a stored proceedure for MSSQL that needs to run for hours at
a time. I need to execute it from C++ code. The current code does:

nRet = SQLDIRECTEXEC(hstmt, "exec stored_proc", SQL_NTS)

followed shortly after by a

Free_Stmt_Handle(hstmt) //roughly

The stored proc currently dies with the statement handle, not fully
populating the table I need it to.

I need to either know when the proc finishes so I can close the handle after
that, or allow the proc to run independently on the server no matter what
the program is doing (is exited, etc), either of these is fine.

Please Help! Thanks in advance!

I know nothing about C++, but if the proc runs for a very long time, it
might be better to implement it as a scheduled job. The client could
set a flag or insert a row into a 'queue' table, then you have a job
which runs every few minutes or whatever, and if the flag is set, it
then starts the stored proc.

That is an interesting approach, ideally I would like to stay as far away
from the database as I can but it sounds like this could be the best way...
my stored procedure is running for the exact same number of instructions and
then dying, whereas if I run it via Query Analyzer it runs to completion.

I finally caved and just copy-pasted from Q.Analyzer into code to confirm
this. I will investigate a little further before taking that plunge.

Thanks
Joseph
