创建日志表

DROP TABLE IF EXISTS `table_change_log`;
CREATE TABLE `table_change_log` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `table_name` varchar(20) NOT NULL DEFAULT '' COMMENT '表名',
  `table_op` varchar(20) NOT NULL DEFAULT '' COMMENT '操作',
  `table_id` int(11) NOT NULL DEFAULT '0' COMMENT '表ID',
  `add_time` datetime NOT NULL COMMENT '添加时间',
  PRIMARY KEY (`id`)
) ENGINE=MyISAM AUTO_INCREMENT=0 DEFAULT CHARSET=utf8 COMMENT='表操作记录';

创建触发器, 跟踪增删改

DROP TRIGGER IF EXISTS `tg_project_users_insert`;
CREATE TRIGGER `tg_project_users_insert` AFTER INSERT ON `project_users`
FOR EACH ROW INSERT INTO table_change_log (`table_name`, `table_op`, `table_id`, `add_time`) VALUES('project_users', 'insert', new.pro_id, NOW());

DROP TRIGGER IF EXISTS `tg_project_users_update`;
CREATE TRIGGER `tg_project_users_update` AFTER UPDATE ON `project_users`
FOR EACH ROW INSERT INTO table_change_log (`table_name`, `table_op`, `table_id`, `add_time`) VALUES('project_users', 'update', old.pro_id, NOW());

DROP TRIGGER IF EXISTS `tg_project_users_delete`;
CREATE TRIGGER `tg_project_users_delete` AFTER DELETE ON `project_users`
FOR EACH ROW INSERT INTO table_change_log (`table_name`, `table_op`, `table_id`, `add_time`) VALUES('project_users', 'delete', old.pro_id, NOW());
