We can use the subquery as a table in the FROM clause just like we use the results and operators of the subquery in the WHERE clause. In the following example, we use it as a table by writing the results of the subquery after the FROM clause. It is mandatory to use alias after subquery, here we use alias 'C_car'. For demonstration we have used the following data from table 'Cars' -
mysql> Select * from Cars; +------+--------------+---------+ | ID | Name | Price | +------+--------------+---------+ | 1 | Nexa | 750000 | | 2 | Maruti Swift | 450000 | | 3 | BMW | 4450000 | | 4 | VOLVO | 2250000 | | 5 | Alto | 250000 | | 6 | Skoda | 1250000 | | 7 | Toyota | 2400000 | | 8 | Ford | 1100000 | +------+--------------+---------+ 8 rows in set (0.02 sec) mysql> Select * FROM ( Select Name, Price from Cars Where Price > 200000) C_car WHERE Name = 'Nexa'; +------+--------+ | Name | Price | +------+--------+ | Nexa | 750000 | +------+--------+ 1 row in set (0.00 sec)
