Selecting Only EVEN or ODD Records from Tables – MS SQL SERVER

Introduction

In this article, we will learn to Select only EVEN or ODD records from the MS SQL Server database table🤔. The efficient way to find the record belongs to even or odd is determining by the table’s ID column.

Select EVEN Records

By applying the modulo operator by 2 for the ID column, we can find the record is even or odd. If the modulo operation’s results equal to Zero or 0, then that record is EVEN. Else ODD record.

Syntax

SELECT * FROM TableName WHERE ColumnName % 2= 0;

Example

From the above table results, lets select EVEN Records

SELECT [StudentId]
,[FirstName]
,[LastName]
,[RegistrationNumber]
,[Degree]
,[CreatedDate]
,[CreatedBy]
FROM [Details].[StudentDetails] WHERE StudentId % 2=0;

Select ODD Records

If the modulo operation result is not equal to Zero or 0, then its ODD record.

Syntax

SELECT * FROM TableName WHERE ColumnName % 2!=0;

Example

SELECT [StudentId]
,[FirstName]
,[LastName]
,[RegistrationNumber]
,[Degree]
,[CreatedDate]
,[CreatedBy]
FROM [Details].[StudentDetails] WHERE StudentId % 2!=0;
