Re: Query problem with date partitioning
There was recently a bug report almost like this:
http://bugs.mysql.com/bug.php?id=36604
And please look at Sergey Petrunia's blog about partitioning pruning optimizations:
http://s.petrunia.net/blog/?p=21
Currently the partitioning and optimizer does not support range pruning on any partitioning type other than 'range'. (there is no range analysis even for unary and monotonic functions for checking if it gives the same result in this case).
Regard Mattias Jonsson
Sun/MySQL software engineer, working with the partitioning code.
