the problem is, i don't know whats the index of order by without knowing the sql, the 'create' table and the optimizer choise/options but i want that optimizer avoid the order by index with a optimizer_switch configuration or a sql hint i don't know if it's possible, i don't want to add a FROM table IGNORE INDEX (some index), i want something like ORDER BY IGNORE INDEXES some_columns
but you won't get that because you *have to know* your tables and queries - "IGNORE INDEXES some_columns" would be by all respect pure stupidity because *everybody* excepts here to list index names
