SQL Server BETWEEN Operator

The BETWEEN operator in SQL Server is used to filter the result set based on a range of values for a specified column. It is often used in the WHERE clause to include rows where the column value is within a specified range. This guide will cover the syntax, examples, output, explanations, use cases, important points, and a summary of using the BETWEEN operator in SQL Server.

Syntax

SELECT column1, column2, ...
FROM table_name
WHERE column_name BETWEEN value1 AND value2;

Example

Consider a table named sales with a column named revenue. We want to retrieve sales records where the revenue is between $10,000 and $50,000.

SELECT order_id, revenue
FROM sales
WHERE revenue BETWEEN 10000 AND 50000;

Output

The output will display the order IDs and revenues for sales records falling within the specified range.

| order_id | revenue |
|----------|---------|
| 101      | 25000   |
| 102      | 45000   |
| 103      | 30000   |

Explanation

• The BETWEEN operator is used to filter rows where the revenue column value is within the range of $10,000 and $50,000.
• The result set includes sales records that meet the specified criteria.

Use

The BETWEEN operator in SQL Server is used for:

• Filtering rows based on a specified range of values.
• Retrieving records that fall within a certain numeric or date range.
• Simplifying queries compared to using multiple conditions with AND.

Important Points

• The range specified with BETWEEN is inclusive, meaning that values equal to value1 or value2 are included in the result set.
• The BETWEEN operator can be used with various data types, including numeric, date, and time types.

Summary

The BETWEEN operator in SQL Server is a powerful tool for filtering data within a specified range. It provides a concise and readable way to express range-based conditions in SQL queries. Understanding how to use the BETWEEN operator is essential for efficiently retrieving data that meets specific criteria within a given range.
