I have thrown complex queries at both Access and MySQL and MySQL wins hands down. It's not even a contest. Heck, MySQL out-performs a comparable Oracle 9i system in certain situations, which impressed me more. This is why our datawarehouse is on MySQL 4.1.4 and not Oracle 9.2.0.5. *shrugs*
Being right, does not endow the right to be rude; politeness costs nothing.
Being unknowing, is not the same as being stupid.
Expressing a contrary opinion, whether to the individual or the group, is more often a sign of deeper thought than of cantankerous belligerence.
Do not mistake your goals as the only goals; your opinion as the only opinion; your confidence as correctness. Saying you know better is not the same as explaining you know better.
