Re: Left join vs Inner join

Thank you so much for your reply. Yes, we are on MySQL version 5.5.46. So when we upgrade to 5.6, does the derived table access change from full table scan to index scan? Since it is a derived table and an index can't be defined on a derived table, how does MySQL use an Index join?
