SQL AND and OR Operators

Last Updated : 23 Jul, 2025

The SQL AND and OR operators are used to filter data based on multiple conditions. These logical operators allow users to retrieve precise results from a database by combining various conditions in SELECT, INSERT, UPDATE, and DELETE statements.

In this article, we'll learn the AND and OR operators, demonstrate their usage with examples, and provide insights on combining them for complex queries.

The AND operator allows you to filter data based on multiple conditions, all of which must be true for the record to be included in the result set.

Syntax:

The syntax to use the AND operator in SQL is:

SELECT * FROM table_name WHERE condition1 AND condition2 AND ...conditionN;

Here,

• table_name: name of the table
• condition1,2,..N: first condition, second condition, and so on.

The OR Operator in SQL displays the records where any one condition is true, i.e. either condition1 or condition2 is True.

Syntax:

The syntax to use the OR operator in SQL is:

SELECT * FROM table_name WHERE condition1 OR condition2 OR... conditionN;

• table_name: name of the table
• condition1,2,..N: first condition, second condition, and so on

Let's look at some examples of AND and OR operators in SQL and understand their working.

Now, we consider a table database to demonstrate AND & OR operators with multiple cases.

If suppose we want to fetch all the records from the Student table where Age is 18 and ADDRESS is Delhi.

Query:

SELECT * FROM Student 
WHERE Age = 18 AND ADDRESS = 'Delhi';

Output:

To fetch all the records from the Student table where NAME is Ram or NAME is SUJIT. 

Query:

SELECT * FROM Student 
WHERE NAME = 'Ram' OR NAME = 'SUJIT';

Output:

Combining AND and OR Operators in SQL allows the creation of complex conditions in queries. This helps in filtering data on multiple conditions. 

Syntax:

Syntax to use AND and OR operator in one statement in SQL is:

SELECT * FROM table_name
WHERE condition1 AND (condition2 OR condition3);

Let's look at example of combining AND and OR operators in a single statement. In this example we will fetch all the records from the Student table where Age is 18, NAME is Ram or RAMESH.

Query:

SELECT * FROM Student WHERE Age = 18 AND (NAME = 'Ram' OR NAME = 'RAMESH');

Output:

• The SQL AND operator is used to combine multiple conditions, where all the conditions must be true for the row to be included in the result set.
  
• The OR operator is used to combine multiple conditions, where at least one of the conditions must be true for the row to be included in the result set.
  
• Any kind of condition, including equality, inequality, comparison, and logical operators, can be utilized with the AND and OR operators.
  
• The AND operator is more important than the OR operator. In other words, when both are used in the same SQL statement, the AND operator will be executed first. To change the order of evaluation, parentheses can be used.
  
• You can employ the AND and OR operators inside of other conditions because they can both be nested.

The AND and OR operators are essential tools for filtering data in SQL. By combining multiple conditions, you can create powerful and efficient queries to retrieve exactly the data you need. Remember to use parentheses for clarity and control the order of evaluation, especially when combining both operators. By mastering these logical operators, you’ll be able to handle complex queries and data filtering tasks more effectively.
