mysql> create table t_trig_test_01 (name varchar(10));
-
Query OK, 0 rows affected (0.07 sec)
-
-
mysql> create table t_trig_test_02 (name varchar(10));
-
Query OK, 0 rows affected (0.03 sec)
-
-
mysql> create table t_trig_test_03 (name varchar(10));
-
Query OK, 0 rows affected (0.03 sec)
创建两个触发器:
-
mysql> delimiter //
-
mysql> create trigger trg_test_01
-
-> after insert on t_trig_test_01
-
-> for each row
-
-> begin
-
-> insert into t_trig_test_02 select * from t_trig_test_01;
-
-> end;
-
-> //
-
Query OK, 0 rows affected (0.06 sec)
-
-
mysql> delimiter //
-
mysql> create trigger trg_test_02
-
-> after insert on t_trig_test_01
-
-> for each row
-
-> begin
-
-> insert into t_trig_test_03 select * from t_trig_test_01;
-
-> end;
-
-> //
-
Query OK, 0 rows affected (0.11 sec)
向表t_trig_test_01插入两条测试数据:
-
mysql> insert into t_trig_test_01 values('steven');
-
Query OK, 1 row affected (0.01 sec)
-
-
mysql> insert into t_trig_test_01 values('steven');
-
Query OK, 1 row affected (0.01 sec)
查看三个表的数据:
-
mysql> select * from t_trig_test_01;
-
+--------+
-
| name |
-
+--------+
-
| steven |
-
| steven |
-
+--------+
-
2 rows in set (0.00 sec)
-
-
mysql> select * from t_trig_test_02;
-
+--------+
-
| name |
-
+--------+
-
| steven |
-
| steven |
-
| steven |
-
+--------+
-
3 rows in set (0.00 sec)
-
-
mysql> select * from t_trig_test_03;
-
+--------+
-
| name |
-
+--------+
-
| steven |
-
| steven |
-
| steven |
-
+--------+
-
3 rows in set (0.00 sec)
达到了预期的结果。
