yep, that's the problem. But MySQL wouldn't do anything else, just a bit faster because there are no queries to "compile". The only problem is, i don't know how to split this field into single values. If this would be possible, you could fill another table3 w/ these values enclosed by % % as patterns and do this: select row from table2,table3 where fields-m like table3.patterns; This should work, regards
