Question : Need help joining 2 queries.

I have a function from an MS Acess 2003 database from end linked to SQL Server 2000 backend. The attached function creates two queries with the required parameters than a third query joins the previous two and returns a recordset.

This works perfectly fine, but now I need to get the same end result (data) into an ASP.NET web page and I'm not sure how to approach it. I'd love to get the three queries into a single SQL statement, but if it's even possible, I'm not slick enough to do it.

Answer : Need help joining 2 queries.

You will notice two @'s in there. These are for you to parameterize. Alternatively, you can always append to the string into those two places.
I take it tblWorkFlowAssignmentsDetail.Completed is a bit field, so as a normal T-sql query, it should be tested against 0 not False.
