Re: Innodb bogs down on complicated query(ies)
I'm glad that the problem was solved. I'm not experienced in reading the EXPLAIN SELECT output, and AFAIK there is no way to request the execution plan for other statements than SELECT.
The temporary directory is specified with mysqld --tmpdir=... or with tmpdir=... in the [mysqld] section of my.cnf. The location is not configureable with an environment variable, since MySQL does not use tmpfile() from the standard library.
