bool | operator() (const JOIN_TAB *jt1, const JOIN_TAB *jt2) |
"Less than" comparison function object used to compare two JOIN_TAB objects that are joined using STRAIGHT JOIN. For STRAIGHT JOINs, the join order is dictated by the relative order of the tables in the query which is reflected in JOIN_TAB::dependent. Table size and key dependencies are ignored here.
