The POWER function is used to raise a number to the power of another number. It takes two arguments, the base and the exponent, both of which must be of the FLOAT type. The result will also be of the FLOAT type.

Syntax​

POWER(base, exponent)

Examples​

  1. Using the POWER function:
SELECT POWER(2.0, 4) as power_1;
-- Result: 16.0
  1. Using the POWER function with a decimal:
SELECT POWER(0.07, 3) as power_2;
-- Result: 0.000343
  1. Using the POWER function with zero:
SELECT POWER(0, 4) as power_with_zero;
-- Result: 0.0

SELECT POWER(3, 0) as power_to_zero;
-- Result: 1.0

Error Cases​

  1. The POWER function requires both arguments to be of FLOAT type:
SELECT POWER('string', 'string') AS power;
-- Error: FunctionRequiresFloatValue("POWER")
  1. The POWER function requires the base to be of FLOAT type:
SELECT POWER('string', 2.0) AS power;
-- Error: FunctionRequiresFloatValue("POWER")
  1. The POWER function requires the exponent to be of FLOAT type:
SELECT POWER(2.0, 'string') AS power;
-- Error: FunctionRequiresFloatValue("POWER")
