Bagaimanakah kita boleh membuat paparan MySQL berdasarkan paparan sedia ada lain?

mysql> Create view info AS Select Id, Name, Subject FROM student_info;
Query OK, 0 rows affected (0.11 sec)

mysql> Select * from Info;
+------+---------+------------+
| Id | Name | Subject |
+------+---------+------------+
| 101 | YashPal | History |
| 105 | Gaurav | Literature |
| 125 | Raman | Computers |
| NULL | Ram | Computers |
+------+---------+------------+
4 rows in set (0.00 sec)

mysql> Create view info_less AS Select Id, Name, Subject FROM info WHERE id >= 120;
Query OK, 0 rows affected (0.25 sec)

mysql> Select * from info_less;
+------+-------+-----------+
| Id | Name | Subject |
+------+-------+-----------+
| 125 | Raman | Computers |
+------+-------+-----------+
1 row in set (0.03 sec)
