Are you using MyISAM? Or InnoDB? Some of what Jon points out depends on the choice of Engine.
> PARTITION p_JAN VALUES LESS THAN (2012-02-01),
That's the same as
PARTITION p_JAN VALUES LESS THAN (2009),
because that is an arithmetic expression. Quote dates.
> PARTITION BY RANGE ( Month(fldconfirmdate))
> PARTITION p_JAN VALUES LESS THAN (2012-02-01),
--> (after switching to DATE or DATETIME from VARCHAR):
PARTITION BY RANGE ( TO_DAYS(fldconfirmdate))
PARTITION p_JAN VALUES LESS THAN (TO_DAYS('2012-02-01')),
Why partition? Will you be DROPping old partitions?
