MYSQL Trigger Copy Entire Row while insert,update - mysql

Question

I have two Table namely admin_user,admin_user_bak
the structure of the table admin_user is
CREATE TABLE IF NOT EXISTS `admin_user` (
`user_id` int(11) NOT NULL AUTO_INCREMENT,
`user_name` varchar(150) NOT NULL,
`name` varchar(150) NOT NULL,
`emailid` varchar(150) NOT NULL,
`password` varchar(150) NOT NULL,
`roll` varchar(50) NOT NULL,
`created` datetime NOT NULL,
`modified` datetime NOT NULL,
`last_login` datetime NOT NULL,
`status` enum('active','inactive') NOT NULL,
PRIMARY KEY (`user_id`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1 AUTO_INCREMENT=1 ;
and structure of table admin_user_bak have all the fields of admin_user and additionally a field bak_user_id . its auto increment id..
CREATE TABLE IF NOT EXISTS `admin_user_bak` (
`bak_user_id` int(11) NOT NULL AUTO_INCREMENT,
`user_id` int(11) NOT NULL,
`user_name` varchar(150) NOT NULL,
`name` varchar(150) NOT NULL,
`emailid` varchar(150) NOT NULL,
`password` varchar(150) NOT NULL,
`roll` varchar(50) NOT NULL,
`created` datetime NOT NULL,
`modified` datetime NOT NULL,
`last_login` datetime NOT NULL,
`status` enum('active','inactive') NOT NULL,
PRIMARY KEY (`bak_user_id`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1 AUTO_INCREMENT=1 ;
here my trigger is
CREATE TRIGGER ins_admin_user BEFORE UPDATE ON admin_user
FOR EACH ROW
BEGIN
INSERT INTO admin_user_bak (user_id,user_name,name,emailid,password,roll,created,modified,last_login,status) VALUES ( NEW.user_id, NEW.user_name, NEW.emailid, new.password, NEW.roll, NEW.created, NEW.modified, NEW.last_login, NEW.status);
END
my purpose is i want to back up all events. insert update delete of a particular record. not all record. i write for insertion. its not working
any idea.. thanks

Answer 1

i want a insertion trigger but you had written update on in your trigger so it's not work.
You use INSERT ON
CREATE TRIGGER ins_admin_user BEFORE INSERT ON admin_user
FOR EACH ROW
BEGIN
INSERT INTO admin_user_bak (user_id,user_name,name,emailid,password,roll,created,modified,last_login,status) VALUES ( old.user_id, old.user_name, old.emailid, old.password, old.roll, old.created, old.modified, old.last_login, old.status);
END
