Synopsis:optimizer bug in selecting fields that don�t belong to the index used by
mysql/innodb
Exectutable: mysqld-max-nt
---------------------------------------------------------------------------------------------------
Since I have the same, but worst, problem with poor performance with
innoDB compared to myISAM, it's not some fluke. However, since an
award was just issued for innoDB, it's probably not the optimizer as
you suggest.
I'd bet that the problem is in the table conversion.
ALTER TABLE xxxx TYPE=innoDB
is not the right way to convert.
