Question

We’ve got a longstanding function that writes the results of a query to a file. This works great. However, now I’m tasked with writing the result of a function to a file The function returns a dataset based on some input parameters. When run by itself in a Query window, results are returned in the Result Pane. But when passed to our “CreateFile” function, a blank file is written (if the return code is trapped).

EXECUTE LoanStatusChangeTracking '2011-5-26','2011-5-27','44000' 

returns 65 rows for today.

DECLARE @Query varchar(MAX)
set @Query = 'EXECUTE [BankA].[dbo].[LoanStatusChangeTracking] ''2011-5-26'',''2011-5-27'',''44000'' '
Exec dbo.Ufn_CreateFile @Query, 'Collections2011-5-27.csv', 'S:\FTPTransferDaily', 'lms_user', 'kkoi8333323', '172.25.200.71', default  

Doesn’t return anything or create a file. I can run it with a simple sql script and results get written.

What would be a likely place to start investigation?

Answer 1

The problem is due to temp tables. They don’t last, of course, and by the time the Create File function ran, there wasn’t anything to write to disk.
