In Sql Server Select Odd Numbers With Command

How to Use SQL Server to Select Odd Numbers

If you’re looking to filter out odd numbers from a dataset in SQL Server, you’ve come to the right place. In this article, we’ll walk you through how to effectively use the SELECT statement to retrieve only the odd numbers from a table. Whether you’re a beginner or an experienced SQL user, this guide will help you hone your skills and streamline your query process.

Understanding the SELECT Statement

Before we dive into selecting odd numbers, let’s first understand the basics of the SELECT statement in SQL Server. This statement is used to retrieve data from one or more tables in a database. It allows you to specify which columns you want to retrieve and apply filters to narrow down your results.

When using the SELECT statement, you can also use functions and mathematical operations to manipulate the data before displaying it. This flexibility is key when working with datasets that require specific criteria for extraction.

Filtering Odd Numbers

Now that you have a grasp of the SELECT statement, let’s focus on how to filter out odd numbers from a dataset. One way to achieve this is by using the modulus operator (%) in conjunction with the WHERE clause. The modulus operator calculates the remainder of a division operation, which can be useful for identifying odd numbers.

When dividing an odd number by 2, the result will always have a remainder of 1. This unique property of odd numbers allows us to easily filter them out using the modulus operator. For example, the following SQL query selects only the odd numbers from a ‘numbers’ table:

SELECT number
FROM numbers
WHERE number % 2 <> 0;

By specifying ‘number % 2 <> 0′ in the WHERE clause, we’re instructing SQL Server to retrieve only those records where the remainder of the division by 2 is not equal to 0. This effectively filters out all even numbers, leaving us with only the odd ones.

Practical Example

Let’s put our newfound knowledge to the test with a practical example. Assuming we have a ‘sales’ table with a column named ‘amount’, we can use the following SQL query to select odd sales amounts:

SELECT amount
FROM sales
WHERE amount % 2 <> 0;

This query will return all odd sales amounts from the ‘sales’ table, allowing us to analyze and manipulate the data as needed. By mastering the art of selecting odd numbers in SQL Server, you can enhance your data querying capabilities and gain valuable insights from your datasets.


In conclusion, using SQL Server to select odd numbers is a powerful technique that can help you streamline your data analysis process. By leveraging the modulus operator and the WHERE clause, you can effectively filter out odd numbers from a dataset and focus on the information that matters most. Remember to practice these techniques in different scenarios to gain a deeper understanding of how they can be applied in real-world situations.
