# SQL Operators

What We Are Learn:

SQL Operators: If you’re new to SQL, this article will help you understand what operators are and the different types of operators available in SQL. You’ll also find SQL query examples showing how they can be used.

We use SQL queries to access the database table’s data. But still, we need to manipulate and retrieve the data as per our requirements. Therefore, we need to perform various arithmetic operations, logical operations, comparison operations, compound operations, etc.

Note: SQL operators filter the table’s data by a specific condition in the SQL statement.

## What are SQL Operators?

Operators in SQL are keywords or symbols that can perform specific logical and mathematical operations on operands. We often use the SQL WHERE clause with logical or mathematical Operators to retrieve results based on a specific requirement.

Operators are used to manipulating data and producing a resultset based on the operator’s function. And also, SQL operators are important when creating a SQL query because they connect two or more conditions. There are various types of SQL operators depending on the operation they perform.

## Types of SQL Operators

SQL operator is categorized into different categories based on the operation they are responsible for performing. Here are the different types of operators in SQL:

Now we are going to every operator and discuss their use in detail and understand how these operators in SQL work in a query with the help of examples.

### SQL Arithmetic Operators

The Arithmetic operator in SQL performs arithmetic computations and operations on numerical data found in database tables. This operator can perform all arithmetic operations, such as addition, subtraction, multiplication, division, and modulus.

Note: SQL Arithmetic Operators are used with the WHERE clause.

### SQL Logical Operators

The Logical operator in SQL compares two data values in the database tables and determines whether they meet specific conditions. The Logical operator will return True if both values meet the specified conditions. Otherwise, it will return False.

Note: SQL Logical Operators are used with the WHERE clause.

We have some special logical operators used to select records from the table. These operators are commonly used inside the WHERE clause or with the HAVING statement.

Here is the list of special logical operators with descriptions.

### Comparison Operator In SQL

The SQL Comparison operator is used to compare two data values present in database tables. The comparison operators can also compare one expression to another expression.

A comparison operation can produce the results TRUE, FALSE, or UNKNOWN. If any of the expressions or both are NULL, the operation returns UNKNOWN.

Note:  Comparison Operator In SQL are used with the WHERE clause.

### SQL Set Operators

The SQL Set operators combine two or more similar data present in different SQL databases. The SQL Set operators merge the result retrieved from each query is combined into a single query result.

Note:  SQL Set Operators are used with the SELECT statements.

Conclusion:

SQL operators are an essential component of the SQL language, which provides a powerful way to manipulate data within a database. They enable users to perform various functions, including filtering, sorting, grouping and joining data from multiple tables. By understanding the different types of operators available in SQL, users can efficiently write complex queries to extract the desired information from large databases. Whether you are a beginner or an experienced SQL user, you should be a master in SQL operators to work with data effectively and efficiently.

We hope this article on SQL operators will guide you with basic ideas on different types of SQL operators like SQL Arithmetic Operators, SQL Logical Operators, Comparison Operators In SQL, and SQL Set Operators.

## SQL Operators FAQs

### What are the 5 types of SQL operators?

There are six kinds of SQL operators: Arithmetic, Bitwise, Comparison, Combination, Logical, and String.

### What is SQL operators?

SQL operator is a reserved word or character used to query our database in a SQL expression. To query a database using operators, we use a WHERE clause.

### What are the 5 arithmetic operators?

These operators are + (addition), – (subtraction), * (multiplication), / (division), and % (modulo).
