The POWER function in SQL returns the value of a numeric expression raised to a specified power. It is useful for performing exponential calculations.

Example:

SELECT POWER(2, 3)

SELECT POWER(base, exponent)

Syntax:

base is the numeric expression to be raised to the power of exponent.

exponent is the power to which the base is raised.

Sample Data:

    
            first_name
            vacation_days
        
            Frank
            5
        
            Jane
            2
        
            Ashley
            3
        
            Glenn
            -3
        
            Kelly
            2
        
            Richard
            -7
        
            George
            2
        
            Kyle
            1
        
            James
            -2
        
            Gustavo
            -10

first_name	vacation_days
Frank	5
Jane	2
Ashley	3
Glenn	-3
Kelly	2
Richard	-7
George	2
Kyle	1
James	-2
Gustavo	-10

Example: Hard-coded value

In this example, we are returning 2 to the power of 3, the final output is 8.

Example: Query without the WHERE Statement

In this example, we are returning the vacation_days column to the power of 2.

Example: Query with the WHERE Statement

In this example, we are returning the vacation_days column to the power of 2 where the first_name equals ‘Kelly.’
