Re: Has anyone found a Viable Solution? (YEP)

I don't know if it's the definitive solution, but it worked for me.

Problem: Query stuck on the 'Copying to tmp table' state. After a while, server hangs.

Situation: Very, very old database whose tables involved in that query didn't have any kind of index (primary, unique, etc.)

Solution: Create an index for each table involved in the query.
