Hi,

I need quick help.

I want to write a function which will take today’s date and reply me the number of weekdays only. For e.g. today is 04-28-2013. Result should be 20. How ?? today’s date minus 8 days as weekend passed. If today’s date is 0-17-2013 then result should be 12.

Catch is to know how many weekends are passed from today’s date. I need to calculate dynamic everyday.

“I assume most of us are using SQL Server 2012…”

Evidently you don’t guys work in the real world. Do you also assume that most of us are using Windows 8?

This has a flaw in it in that it doesn’t consider the setting of @@DATEFIRST. In the US, they number Sunday as 1, Monday as 2 etc. Most other countries use Monday as 1, Tuesday as 2.

This can be changed with the SET DATEFIRST command.

Here’s my attempt, it will give consistent results whatever the setting of @@DATEFIRST is:

SELECT today = datemaker.date,
name = DATENAME(dw, datemaker.date),
daynumber = 1 + ((DATEPART(dw, datemaker.date) + @@DATEFIRST – 2) % 7)
FROM (
– Make a list of dates starting from tomorrow
SELECT TOP 21
date = DATEADD(d, ROW_NUMBER() OVER (ORDER BY id), CONVERT(date, GETDATE()))
FROM sys.sysobjects
) datemaker

we can use the following code also in SQL

SELECT CATEGORY =
CASE (DATENAME(DW,GETDATE()))
WHEN ‘SATURDAY’ THEN ‘WEEKEND’
WHEN ‘SUNDAY’ THEN ‘WEEKEND’
ELSE ‘WEEKDAY’
END
