SQL Operators: The Arithmetic Operators And The Concepts Behind It.

What Are SQL Arithmetic Operators?

SQL Arithmetic operators are operators that are used for calculating mathematical operations like the sum of two numbers or the division of two numbers or the calculation of the salaries of a particular company based on their database. In SQL, they are useful when you want to perform math operations on data in tables while you retrieve them by writing SQL SELECT queries. In summary, arithmetic operators are used to perform mathematical operations on data. They can be found in the SELECT clause as well as the WHERE clause in the SQL SELECT statement. Let us now get to know more about what the term “operator” means.

What Are Operators?

Operators are specific words or characters that help you to perform different activities in a database. They are like a conjunction or what you use to compose a sentence or an operation. The question therefore is, why do you need to know about operators?

Why Do You Need To Know About Operators?

When handling data in a database, at some point, you will need to query and manipulate data for different purposes. Using SQL operators allows you to manipulate data for different purposes in order to perform various activities in the database.

Types Of Arithmetic Operators.

There are various types of arithmetic operators in SQL, each with different functions. They are commonly used to perform arithmetic or mathematical operations(a calculation that yields a common result). They are:

Plus Symbol(+) for addition operations.

Minus symbol(-) for subtraction operations.

Asterisk symbol(*) for multiplication operations.

Forward slash(/) for division operations.

Percentage symbol(%) for the modulus operation which provides the remainder value of a division.
