Are you sure this is what you really want? MONTH() is never greater than
12, so your query is equal to:
SELECT * FROM `sav00_sav

SELECT * FROM `sav00_sava0400_dbf`
emissao BETWEEN '2000-01-01' AND '2000-12-31'
UNION ALL
SELECT * FROM `sav00_sava0400_dbf`
emissao BETWEEN '1999-12-01' AND '1999-12-31'
Why not:
SELECT * FROM `sav00_sava0400_dbf`
emissao BETWEEN '1999-12-01' AND '2000-12-31'
?? ;)

Hi,
Try this...
Do an "alter" and create indexes on the following fields of your tables:
-wmkt_email_sent.fkemail
-wmkt_client.fkemail
-wmkt_maillist_client.fkclient
... and i think it's a good idea if you create indexes on the primary keys
of each table.It's redundant but have some "effect".
