Suggestions to make .sql files more efficient

[syntoad]

If you make a database that is supposed to override previous databases, it's probally best to use REPLACE instead of INSERT, that way it will actually overwrite the info that is already there (and not give you back so many errors.)

And while I'm at it, it is also desirable to use a multipule insert statement, as it will execute much faster than a lot of inserts.

For example:

INSERT INTO items VALUES (1001, 'item1001'),
INSERT INTO items VALUES (1002, 'item1002'),
INSERT INTO items VALUES (1003, 'item1003');

becomes:

REPLACE INTO items VALUES (1001, 'item1001'),
 (1002, 'item1002'),
 (1003, 'item1003');

This should make db upgrades easier and faster.
