SQL BETWEEN Operator Tutorial 🎯

Welcome to our deep dive into the SQL BETWEEN Operator! In this comprehensive guide, we'll explore everything you need to know about this powerful tool that helps filter records in a database based on a range of values. 📝

What is the SQL BETWEEN Operator? 💡

The BETWEEN operator is a SQL keyword used to specify a range of values to select rows from a database table. It takes two arguments: the start and end values of the range.

sql
SELECT column_name FROM table_name WHERE column_name BETWEEN start_value AND end_value;

Why Use the SQL BETWEEN Operator? 📝

The BETWEEN operator simplifies the process of selecting data within a specific range. Instead of writing two separate >= and <= comparisons, you can use the BETWEEN operator for a more readable and concise SQL query.

Syntax and Examples 💡

Here's the basic syntax of the BETWEEN operator:

sql
SELECT column_name FROM table_name WHERE column_name BETWEEN start_value AND end_value;

Example 1: Selecting ages between 18 and 25

sql
SELECT age FROM Users WHERE age BETWEEN 18 AND 25;

Example 2: Selecting salaries greater than or equal to 50000 and less than or equal to 100000

sql
SELECT salary FROM Employees WHERE salary BETWEEN 50000 AND 100000;

Important Notes 📝

  • Remember to use single quotes around string values when using the BETWEEN operator.
  • The BETWEEN operator is inclusive of both start and end values.
  • If you want an exclusive range, use NOT BETWEEN operator.
