The query works just fine using he SQL Query Analyzer but with either TQuery or TADOQuery I get errors. I was reading around the web and saw several references to a "pass-through" where the SQL query text can be sent directly to the SQL Server. However I didn't see anything about how to actually do a pass-through. How do I do a pass-through or is there some other way for me to execute the query and get the resultant set of records?

In QA, select ToolsOptions in menu, then Connection Properties tab. Thise properties QA sets for connection that is used to execute query (it is not ADO, but it works the same way). Try to add these properties into your script, such as SET ANSI_NULLS ON. //------------------------------------------ Regards, Vassiliev V.

I'm pretty sure I'm not doing it the "standard approved" method. Maybe you could suggest the "standard approved" method of doing it. Here is what I use now.

[name] = '#TempTable' seems to be more appropriate here. //------------------------------------------ Regards, Vassiliev V.
