EXEC Query Performance

I am running into a situation where a program runs a stored procedure, withi
n that stored procedure a SQL statement is built and then executed using the
EXEC command. It looks like that when the generated statement exceeds a ce
rtain time threshold, the s
tored procedure exits without any warning.
I know there is no warning because I have run profiler and I get a statement
start time but no end time. I have also logged every step in the stored pr
ocedure and it just bails on me. Any ideas?Funny you mention that Peter, I run the stored procedure in QA and it runs f
ine. The funny thing is that when the stored proc fails, the rest of the pro
cess completes. I have not been able to get access to the .Net code to view
how it is executed yet.

code the developer uses to call this. Can any of you see anything wrong wi
th this code?
Dim cnTemp As Connection
Dim rsTemp As Recordset '--ADODB.Recordset
Dim strSQL As String
Set cnTemp = New ADODB.Connection
Set rsTemp = New ADODB.Recordset
cnTemp.ConnectionString = "Provider=SQLOLEDB;Data Source=PowerWare2000;Initi
al Catalog=PWProd; User ID=*******;Password=********;"
cnTemp.Open
strSQL = "Exec " & SP_CreatePrintJob & " " & JobTicketNr
rsTemp.CursorLocation = adUseClient
rsTemp.CursorType = adOpenStatic
rsTemp.LockType = adLockOptimistic
rsTemp.Open strSQL, cnTemp, , , adCmdText

seconds. This should help with that:

But you also want to optimize these queries so they don't take so long to
begin with. Using stored procedures with parameters instead of adhoc sql is
a good start.
