SQL SERVER – Find Weekend and Weekdays from Datetime in SQL Server 2012
- by pinaldave
Yesterday we had very first SQL Bangalore User Group meeting and I was asked following question right after the session.
“How do we know if today is a weekend or weekday using SQL Server Functions?”
Well, I assume most of us are using SQL Server 2012 so I will suggest following solution. I am using SQL Server 2012′s CHOOSE function. It is
SELECT GETDATE() Today,
DATENAME(dw, GETDATE()) DayofWeek,
CHOOSE(DATEPART(dw, GETDATE()), 'WEEKEND','Weekday',
'Weekday','Weekday','Weekday','Weekday','WEEKEND') WorkDay
GO
You can use the choose function on table as well. Here is the quick example of the same.
USE AdventureWorks2012
GO
SELECT A.ModifiedDate,
DATENAME(dw, A.ModifiedDate) DayofWeek,
CHOOSE(DATEPART(dw, A.ModifiedDate), 'WEEKEND','Weekday',
'Weekday','Weekday','Weekday','Weekday','WEEKEND') WorkDay
FROM [Person].[Address] A
GO
If you are using an earlier version of the SQL Server you can use a CASE statement instead of CHOOSE function.
Please read my earlier article which discusses CHOOSE function and CASE statements. Logical Function – CHOOSE() – A Quick Introduction
