An error is only thown during an INSERT or UPDATE statement, otherwise you just get a warning. - ERROR_FOR_DIVISION_BY_ZERO Produce an error in strict mode (otherwise a warning) when we encounter a division by zero (or MOD(X,0)) during an INSERT or UPDATE. If this mode is not given, MySQL instead returns NULL for divisions by zero. If used in INSERT IGNORE or UPDATE IGNORE, MySQL generates a warning for divisions by zero, but the result of the operation is NULL.
