In addition to the answer from  WoLpH   When using the LIKE keyword you also have the ability to limit which direction the string matches  For example   If you were looking for a string that starts with your  needle       WHERE column LIKE    needle      If you were looking for a string that ends with the  needle       WHERE column LIKE     needle

Quite simple actually   mysql query   SELECT   FROM  table  WHERE  column  LIKE     needle          The   is a wildcard for any characters set  none  one or many   Do note that this can get slow on very large datasets so if your database grows you ll need to use fulltext indices
