3 selects against one, well depends what the user wants and how he values code optimizing (versus executing optimizing) this might be somewhat better approach: SELECT stringvar FROM tablename WHERE FIND_IN_SET('BINGO',REPLACE(UCASE(stringvar),' ',',')) > 0; So like, first string is converted to uppercase, then all spaces are made to colons, and then function find_in_set uses word "BINGO" to locate if the textfield actually containts that word. Should be quite exact match allthou i dont guarantee it to work (didnt test it, should work thou) Example: "I want to BinGo, would you want to come ?" -> would translate to "I WANT TO BINGO, WOULD YOU WANT TO COME ?" -> would translate to "I,WANT,TO,,,BINGO,,WOULD,YOU,WANT,TO,COME,?" And result for find_in_set for this string would be 6 so it would match.. -- | ,_, Jani Mikkonen, bofh and proud of it, +358456700349 |(O,O) http://www.mikkonen.org/jani |( ) Pgp public key @ http://www.mikkonen.org/jani/keyh.html +-"-"-------] And i repeat, I do not make mistakes that count. |
