I always like Maurice Wilkes' quote about this:

"I can remember the exact instant when I realized that a large part of my life from then on was going to be spent in finding mistakes in my own programs."

That was back in the late 40s, I believe, so this has been going on for a while! It doesn't help that SQL, as a language, isn't really well designed for debugging--it's one of the few languages I've used where I find it faster to just rewrite a line of code that isn't working rather than try to figure out why it isn't.
