MariaDB POW() Function

The MariaDB POW() function returns the base raise to the power of exponent. In special cases it returns the following:

If the exponent is zero, then 1 is returned.

The POW() function is a synonym for the POWER() function.

Syntax

POW(base, exponent)

Parameters

`base`	`Required.` Specify the base.
`exponent`	`Required.` Specify the exponent.

Return Value

Returns the base raise to the power of exponent.

Example 1:

The example below shows the usage of POW() function.

SELECT POW(5, 2);
Result: 25

SELECT POW(3, 5);
Result: 243

SELECT POW(5.5, 2);
Result: 30.25

SELECT POW(5.5, 2.1);
Result: 35.87250030349099

SELECT POW(5, -1);
Result: 0.2

SELECT POW(5, 0);
Result: 1

SELECT POW(0, 5);
Result: 0

Example 2:

Consider a database table called Sample with the following records:

Data	x
Data 1	0.5
Data 2	1
Data 3	5
Data 4	10
Data 5	50

The statement given below can be used to calculate the square root of column x.

SELECT *, POW(x, 0.5) AS POW_Value FROM Sample;

This will produce the result as shown below:

Data	x	POW_Value
Data 1	0.5	0.7071067811865476
Data 2	1	1
Data 3	5	2.23606797749979
Data 4	10	3.1622776601683795
Data 5	50	7.0710678118654755

Example 3:

Consider a database table called Sample with the following records:

Data	x	y
Data 1	0.5	2
Data 2	1	3
Data 3	5	4
Data 4	10	3
Data 5	50	3

To calculate the records of column x raised to the power of records of column y, the following query can be used:

SELECT *, POW(x, y) AS POW_Value FROM Sample;

This will produce the result as shown below:

Data	x	y	POW_Value
Data 1	0.5	2	0.25
Data 2	1	3	1
Data 3	5	4	625
Data 4	10	3	1000
Data 5	50	3	125000
