Gurus,
I've followed the link that Sureshy pointed out, But I'm more confused after reading it. How do you interpret explain plan? Do you read it from inside out, top to bottom, or bottom to top? I don't see the pattern from the examples given on this document. Could some one be kind enough to explain "how do you read an explain plan"? Thanks so much.
Hi,
You read the explain plan from inside out then top bottom.
