Use MySQL POWER Function with Column Data Values

If we want to use POWER() function with column’s data values then the first argument i.e. the base would be the name of the column and the second argument i.e. the exponent would be as specified by us. To understand it considers a table ‘Employee’ having the following records −

mysql> Select * from Employee;
+----+--------+--------+
| ID | Name   | Salary |
+----+--------+--------+
| 1  | Gaurav | 50000  |
| 2  | Rahul  | 20000  |
| 3  | Advik  | 25000  |
| 4  | Aarav  | 65000  |
| 5  | Ram    | 20000  |
| 6  | Mohan  | 30000  |
| 7  | Aryan  | NULL   |
| 8  | Vinay  | NULL   |
+----+--------+--------+
8 rows in set (0.00 sec)

Now, the query below will raise the power of column ID data values

mysql> Select ID, POWER(ID,2) from Employee;
+----+-------------+
| ID | POWER(ID,2) |
+----+-------------+
| 1  |           1 |
| 2  |           4 |
| 3  |           9 |
| 4  |          16 |
| 5  |          25 |
| 6  |          36 |
| 7  |          49 |
| 8  |          64 |
+----+-------------+
8 rows in set (0.63 sec)
