Hi, i have the following problem. I have a table wherey to_id and owner_id are of type unsigned int not null and both are normal indexes. Unluckily a query like: ------ EXPLAIN SELECT * FROM `telegramme` WHERE to_id = 3157 or owner_id = 3157 ------ returns very bad results: ------ table type possible_keys key key_len ref rows Extra telegramme ALL to_id,owner_id NULL NULL NULL 11488 where used ------ how could this be optimized or is this a bug of mysql, because the indexes exist but are not used (even if specified with use index(..)) ?!
