创建MySQL视图时，如何结合使用逻辑运算符？
MySQL视图可以通过使用逻辑运算符（例如AND，OR和NOT）的组合来创建。可以通过以下示例进行说明-
示例
mysql> Create or Replace View Info AS select ID, Name, Address , Subject FROM Student_info WHERE (Subject = 'Computers' AND ADDRESS = 'Delhi') OR (Subject = 'History' AND Address = 'Amritsar'); mysql> Select * from Info; +------+-------+---------+-----------+ | ID | Name | Address | Subject | +------+-------+---------+-----------+ | 133 | Mohan | Delhi | Computers | +------+-------+---------+-----------+ 1 row in set (0.00 sec)
