Stored procedure problem please help
-
Hello
I have a stored procedure that returns a value correctly the first time through a application an hour later the stored procedure returns the value again with wrong data.
First Time = Returns a parent with child results (correct)
Second time - Returns the same parent with different child results (incorrect)
When executing it through the database all result come back correctly.
This has happen three times yesterday.
stored proc
CREATE procedure prProcessFSM500
(
@LineId smallint --14 for FSM500
,@ClientId int
,@Cards varchar(1000)

,@BrickId varchar(20) output --MES generated

end
end
end
end
GO
Not sure if this has being cached if so the how do i remove the result set from cache. I only know of removing the stored proc from cache DBCC FREEPROCCACHE Is there any way of avoiding this from happening
The stored procedure is executed from the database every 5 sec.
Please advise
Thanks

I won't pretend that I understand what the proc is doing, but I would look at two things:
either the app is sending the wrong parameters?
or if you have connection pooling set to ON, this might be messing it up?
Just speculating, though...

I'd dig into the data. If it's returning things you don't expect, I usually look for data problems.

Digging into the data is always a good idea, though the poster explained it as the 'error' occured when running from the app, but when validating the same thing 'directly' it worked as expected - thus the data should be ok...
At least that's how I understood the problem...
