如何从单个查询中获取多个 MySQL 表的输出?

#We know that a query can have multiple MySQL statements, followed by a semicolon. Suppose if we want to get results from multiple tables, consider the following example to get the result set from "Student_info" and "Student_detail" by writing a single query -

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 |
