Could anyone kindly tell me what's wrong? You should re-write your stored proc to drop the temp table if it exists, then you won't ever have this issue IF (SELECT object_id('TempDB..##Temp')) IS NOT NULL BEGIN DROP TABLE ##Temp END Since you chose to use a global temporary table ##Temp , it is visible to all SQL connections at any given time.

Apparently, I can't use them. I'm getting an error message like: Invalid use of a side-effecting operator 'SELECT' within a function If I want to do something like this: select bleh into #temp from Blah ... inside a function.

Step 2 of job is where failure occurs. Please help! EXEC msdb.dbo.sp_send_dbmail @profile_name= 'MyDBA', @recipients= 'Mack@mydba.co.za', @subject='Log Warning', @query='SELECT * from #TempForLogSpace WHERE LogSpaceUsed >80 You can't query from a temp table using database mail.

I have a stored procedure that is working with a large amount of data. I have that data being inserted in to a temp table. The overall flow of events is something like CREATE #TempTable ( Col1 NUMERIC(18,0) NOT NULL, --This will not be an identity column. ,Col2 INT NOT NULL, ,Col3 BIGINT, ,Col4 VARCHAR(25) NOT NULL, --Etc... -- --Create primary key here? ) INSERT INTO #TempTable SELECT ... FROM MyTable WHERE ... INSERT INTO #TempTable SELECT ... FROM MyTable2 WHERE ... -- -- ...or create primary key here? My question is when is the best time to create a primary key on my #TempTable table? I
