mysql怎么把多条SQL写在一起

可以使用分隔符;

参考如下

mysql> show tables;desc j;
+--------------+
| Tables_in_jm |
+--------------+
| books        |
| j            |
| jb           |
| num          |
| tester       |
+--------------+
5 rows in set (0.00 sec)

+-------+------+------+-----+---------+-------+
| Field | Type | Null | Key | Default | Extra |
+-------+------+------+-----+---------+-------+
| date  | time | YES  |     | NULL    |       |
+-------+------+------+-----+---------+-------+
1 row in set (0.00 sec)
