Hi Folks ALTER TABLE main_db ADD CONSTRAINT FOREIGN KEY( Code, Kana) REFERENCES Syoyu_db( Code, Kana) ON DELETE CASCADE ; works fine. But how to drop the constraint or modify the constraint ? Simply changing ADD to DROP or MODIFY throws errors regards --------------------------------------------------------------------- Before posting, please check: http://www.mysql.com/manual.php (the manual) http://lists.mysql.com/ (the list archive) To request this thread, e-mail <[EMAIL PROTECTED]> To unsubscribe, e-mail <[EMAIL PROTECTED]> Trouble unsubscribing?
