# How to Calculate a Square in SQL

To quickly and easily find the square of a number using SQL, use the POWER function. This function takes two arguments, the number you want to calculate the square of, and the power you want to raise it to. For example, if you wanted to calculate the square of the number 5, you would use the following query:

## Examples

Let's look at a few examples of how this function can be used. Suppose you have a table called numbers with the following data:

If you wanted to calculate the square of each number in this table, you would use the following query:

This query would return the following result:
