mysql> select * from aa;

| id   |
+------+
|    2 |

1 row in set (0.00 sec)

mysql> select * from bb;
+------+
| id   |
+------+
|    2 |
+------+
1 row in set (0.00 sec)

mysql> update aa,bb set aa.id=3, bb.id=3 where aa.id=bb.id;
Query OK, 2 rows affected (0.02 sec)
Rows matched: 2  Changed: 2  Warnings: 0

mysql> select * from bb;
+------+
| id   |
+------+
|    3 |
+------+
1 row in set (0.00 sec)

mysql> select * from aa;
+------+
| id   |
+------+
|    3 |
+------+
1 row in set (0.00 sec)

如果需要强制同步操作,可以使用事务
