我们知道一个查询可以有多个 MySQL 语句，后跟一个分号。假设如果我们想从多个表中获取结果，请考虑以下示例，通过编写单个查询从“Student_info”和“Student_detail”获取结果集 -

mysql> Select Name, Address from Student_info; Select Studentid, Address from Student_detail;
+---------+------------+
| Name    | Address    |
+---------+------------+
| YashPal | Amritsar   |
| Gaurav  | Chandigarh |
| Raman   | Shimla     |
| Ram     | Jhansi     |
| Shyam   | Chandigarh |
| Mohan   | Delhi      |
| Saurabh | NULL       |
+---------+------------+
7 rows in set (0.00 sec)

+-----------+------------+
| Studentid | Address    |
+-----------+------------+
| 100       | Delhi      |
| 101       | Shimla     |
| 103       | Jaipur     |
| 104       | Chandigarh |
| 105       | Chandigarh |
+-----------+------------+
5 rows in set (0.00 sec)

在上面的示例中，在一行中输入了两条语句，并用分号分隔，我们按顺序得到了输出。
