Re: Reg table design and query performances
Hi,
Which version of MySQL are you using?
Your query will be much quicker on 5.6 than on 5.5 since MySQL 5.6 will create indexes on the temporary tables created from the subqueries. MySQL 5.7 should be even faster since temporary tables should not be needed at all.
