Re: How to partition by a period of time

CURDATE() isn't a supported function* and nested function calls aren't allowed in partitioning expressions.

One way you might be able to do this is to add an INT column to store the age in days, then set this column's value using a trigger. You'll also need to include this column in the table's primary key.

*It doesn't appear in the list at http://dev.mysql.com/doc/refman/5.1/en/partitioning-limitations-functions-supported.html - I think we'll be reorganising this section of the documentation soon, as the current arrangement seems to be causing some confusion.
