You re close   The LIKE operator works with strings  CHAR  NVARCHAR  etc    so you need to concattenate the     symbol to the string       MS SQL Server   SELECT   FROM table1 table2 WHERE table1 x LIKE table2 y          Use of LIKE  however  is often slower than other operations   It s useful  powerful  flexible  but has performance considerations   I ll leave those for another topic though       EDIT   I don t use MySQL  but this may work     SELECT   FROM table1 table2 WHERE table1 x LIKE CONCAT table2 y
