MySQL 中如何将 ROW 选择和 COLUMN 选择结合起来?

To combine row selection with column selection, we can use the "WHERE" clause. For example, we have the following table -

mysql> Select * from Student;
+--------+--------+--------+
| Name   | RollNo | Grade  |
+--------+--------+--------+
| Gaurav | 100    | B.tech |
| Aarav  | 150    | M.SC   |
| Aryan  | 165    | M.tech |
+--------+--------+--------+
3 rows in set (0.00 sec)

Now, the following query will show how to combine row selection with column selection using WHERE clause.

mysql> Select Name, RollNo, Grade from Student where Grade='M.Sc' or Grade='B.Tech';
+--------+--------+--------+
| Name   | RollNo | Grade  |
+--------+--------+--------+
| Gaurav | 100    | B.tech |
| Aarav  | 150    | M.SC   |
+--------+--------+--------+
2 rows in set (0.00 sec)
