Oracle Optimizer Statistics

Accidentally messing up table statistics is probably the single most common cause for poor SQL query performance that I've ever seen. At Karen Morton's blog, you'll find a link to the best paper on the subject that I've ever seen.

Karen is going to present this topic at the Hotsos Symposium here in Dallas in just a few weeks. I'll hope to see you there. This one's big: Chris Date.
