I have a SQL Server 2005 stored proc which returns two result sets which are different in schema.
Another stored proc executes it as an Insert-Exec. However I need to insert the first result set, not the last one. What's a way to do this?

Here's an argument for SPs that I haven't heard. Flamers, be gentle with the down tick,
Since there is overhead associated with each trip to the database server, I would suggest that a POSSIBLE reason for placing your SQL in SPs over embedded code is that you are more insulated to change without taking a performance hit.
For example. L...

I'm currently on a co-op term working on a project nearing completion with one other co-op student. Since this project has been passed down from co-op to co-op, poor practices have been taken along the way and testing has been left until the end. I've decided I'd like to write unit-tests to learn something new while testing.
