Well, I assume the question I answered was a classroom or homework assignment, so you can't blame a DBA for what was required. In the interest of full disclosure, I did rant about the assignment, assignments like it, and the idiot instructors that come up with this crap, in my answer.

Functions slow queries down. Not a valid workaround. What I want is a simple way to replace repetitive code that always seems to be found SQL queries.
