mysql 触发器操作

定义触发器:

  1: USE dbtest;
  2: DELIMITER ;;
  3: 
  4: CREATE TRIGGER tr_ondel_test1 AFTER DELETE ON testtable1
  5: FOR EACH ROW BEGIN
  6: DELETE FROM testtable2 where testtable2.FID= OLD.ID;
  7: END;;
  8: 
  9: DELIMITER ;

删除触发器：

  1: DROP   TRIGGER  dbtest.tr_ondel_test1;

查看触发器：

  1: SHOW TRIGGERS FROM dbtest;
  2: 
  3: SHOW TRIGGERS FROM dbtest LIKE ‘%ondel%’;

导出存储过程和触发器：

  1: mysqldump -u root -p123456 --default-character-set=gbk --triggers dbtest >./bk.sql
