Does anyone know if I can add a hint SQL_BUFFER_RESULT to INSERT .. SELECT ON DUPLICATE
ex.. INSERT INTO foo SELECT SQL_BUFFER_RESULT* FROM bar ON DUPLICATE KEY UPDATE foo.X=.. Both my tables foo and bar are InnoDB; but the idea is to release the lock on bar as soon as possible by moving the results to temp table to accommodate slow inserts.. Any reco or does SQL_BUFFER_RESULT work in this case ? Thanks
