MySQL 5.0 has this ability. Check STRICT_ALL_TABLES and

STRICT_TRANS_TABLES SQL modes at:



  http://dev.mysql.com/doc/refman/5.0/en/server-sql-mode.html

















>>  CREATE TEMPORARY TABLE t1 (

>>    i TINYINT

>>  );

>>

>>  INSERT INTO  t1 VALUES (42);

>>

>>  SELECT * FROM t1;

>>  -- Ok, shows 42

>>

>>  UPDATE t1 SET i = 4242;

>>  -- SHOW WARNINGS;

>>

>>  SELECT * FROM t1;

>>  -- Oops, shows 127

>

> Yeah, total rubbish.
