Easy SQL: Cube Root and Natural Log

by daco2020 2022. 5. 27.

Given the following table 'decimals':

** decimals table schema **

  • id
  • number1
  • number2

Return a table with two columns (cuberoot, logarithm) where the values in cuberoot are the cube root of those provided in number1 and the values in logarithm are changed to the natural logarithm of those in number2.

 

 

Solution:

SELECT 
  CBRT(number1) as cuberoot,
  LN(number2) as logarithm
FROM 
  decimals

The cube root is the CBRT function,
The natural logarithm can be found using the LN function.

 

 

 

Result:

cuberoot logarithm
