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:

SELECT POWER(5, 2);

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:

SELECT number, POWER(number, 2) FROM numbers;

This query would return the following result:

number  POWER(number, 2)
------------------------
2       4
3       9
4       16
5       25

Additional Info

The POWER function is supported by most major databases, including MySQL, PostgreSQL, and SQL Server. However, the syntax may vary slightly depending on the database you are using. For more information, check out the documentation for your particular database. 🤓
