How to Multiply Two Columns in SQL

Do you need to multiply two columns in your database? You're in luck! SQL has a handy way of multiplying two columns together that can help you get the answer you need.

The Solution

The solution is to use the SELECT statement with the * operator. This operator takes two arguments, which are the two columns you want to multiply. For example, if you wanted to multiply the price and quantity columns of your database, you would use the following query:

SELECT price * quantity FROM table_name;

Examples

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

If you wanted to multiply the price and quantity columns of this table, you would use the following query:

SELECT price * quantity FROM orders;

This query would return the result 20, 60, 60, since the first row has a price of 10 and a quantity of 2, the second row has a price of 20 and a quantity of 3, and the third row has a price of 15 and a quantity of 4.

Additional Info

The SELECT statement with the * operator 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. 🤓Do you need to multiply two columns in your database? You're in luck!
