Hi All, Is there a way of looking at how mysql builds the query plan and executes it for a given query? EXPLAIN is definitely a useful tool, but it is not exact (shows approximations as far as I can see), furthermore I want something like how the predicates were applied (before or after JOINS), which indexes were used, etc. Basically, Oracle's EXPLAIN PLAN and SQL TRACE do this, and it is very very useful for optimizing queries. Don't get me wrong, I love mysql, but with mysql, you optimize queries more by trial and error, instead of understanding what exactly is going on.
