Try: select somefields from t1 join t2 on t1.id = t2.id and t2.x2 = somenumber; Also take a look at the estimate number of records for each step in the explain output. It's often faster to have a low number of records for each step than to have an optimal join type. The optimizer in MySQL needs help a lot of times. I've found that I sometimes need to use IGNORE_INDEX or even FORCE_INDEX to get MySQL to use the right index.
