I've got some simple questions on tuning SQL. Please reply with references,
I'm not looking for guesses.
* If you have a SELECT statement with a WHERE clause and 2 AND
clauses, which one is processed first, the WHERE clause, the first AND
clause, or the second AND clause?
* Is there any performance loss in using "<>" over "!="?
