Unanswered: can someone explain?
Hi guys, what's up?
can someone explain to me, what's the diffrence between
SELECT... FOR UPDATE; ?
My 2nd question is:
Does someone know about very good manual or tutorial (on the web) where can I find something about EXPLAIN PLAN and about optimization queries by EXPLAIN PLAN...
thanx a lot
Re: can someone explain?
1) SELECT alone does not lock the records selected; SELECT ... FOR UPDATE does.
2) Have you tried the Database Performance Tuning Guide and Reference ?
