How to Subtract One Value from Another in SQL
If you need to subtract one value from another in your SQL database, use the SUBTRACT() function. This function takes two arguments, which are the two values you want to subtract from each other. For example, if you wanted to subtract the value in the price column from the value in the discount column, you would use the following query:
Let's look at a few examples of how this function can be used. Suppose you have a table called products with the following data:
If you wanted to subtract the discount from the price for each product, you would use the following query:
This query would return the results 5.00, 10.00, and 15.00, respectively.
The SUBTRACT() 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.
