Re: Server just hanging (Copying to tmp table)

I'm not extremely versed in SQL and I've always just used left joins no matter what. I have tried to look up the difference between an inner join and a left join and even in the mysql table it refers to an inner join as "inner / left join" so I figure okay, left join.

I guess I need more research on what joins I should be using where.

I know enough to be dangerous. Thanks for being patient!
