The SQL GROUPING is one of the Aggregate Functions, which is used to indicate whether the specified column in a GROUP BY Clause aggregated or not. This Grouping function will return one for aggregated and zero for not aggregated.
SQL Grouping Function Syntax
The basic syntax behind this Grouping in SQL Server is as shown below:
SELECT GROUPING ([Column_Name]) FROM [Source] GROUP BY [Column_Name]
For this grouping function example, we are going to use the [MyEmployee table].
SQL Grouping Function Example
The Grouping in SQL Server returns whether the grouping on the defined column has happened or not, by returning 0 and 1. In this example, we will show you the same.
-- GROUPING in SQL Server USE [SQL Tutorial] GO SELECT [Education] ,[Occupation] ,GROUPING([Occupation]) AS 'Grouping' ,GROUPING([Education]) AS 'Grouping 2' ,SUM([YearlyIncome]) as income FROM [MyEmployees Table] GROUP BY [Education] ,[Occupation] WITH ROLLUP
The following Aggregate Function statements check whether the Grouping performed on the Education, and Occupation columns ar not by returning 1 and 0
,GROUPING([Occupation]) AS 'Grouping' ,GROUPING([Education]) AS 'Grouping 2'
