Re: Django SQL Query does not stop

I found a solution be changing the MySQL server setting optimizer_search_depth to 3 (default 62)

http://dev.mysql.com/doc/refman/5.0/en/controlling-optimizer.html
http://dev.mysql.com/doc/refman/5.0/en/server-system-variables.html#sysvar_optimizer_search_depth

My query had over 20 INNER JOINTS and it made the optimizer search a long process.

So at the moment a value of 3 is fine.
