I have to use some raw SQL to write some queries...One of those raw SQL queries fetches the primary key of a row. I then need to use that primary key to form the basis of another raw SQL query.

When I try to print the information out it doesn't look right to the eye.  Anyone have anything idea's on how I might do this?
