RE: Do programmers tune SQL?

Those of you who have been on the list for a few years probably remember me asking stupid questions when I was a duh-veloper. (I remember one in particular where I flipped out because I didn't remember the difference between UNION and UNION ALL and got my a$$ handed to me.)

My two cents: Not all DBA's know how to tune SQL, either. When there is a big problem here, I usually get a phone call and a request to look over a tkprof/explain/sql statement. Of course it is always urgent.

I have taught a couple of duhvelopers to do it - however I am not going to hold their hands through it. I have gladly helped with some complex statements and explain plans, but usually end up explaining the basics and then handing them Harrison's tuning book and offering to answer questions. If the person doesn't take the initiative, he or she won't remember a word I said.
