We are creating a SQL Server Table-value function to get weekdays between two dates. Logic is simple as DatePart(dw,Getdate()) returns integer value of the day. Sunday is equivalent to 1 and Monday is equivalent to 2 and so far. As we know weekdays are from Monday to Friday. So all the days between 2 and 6(including these two) are weekdays. Here is the code for the same.

Create function dbo.getWeekDays(@startdate date, @enddate date)
returns  @temptable TABLE (weekDays varchar(100),Name Varchar(100)) 
As
Begin
     Declare @weekday date
	 While  @startdate <= @enddate
	 Begin
	    IF DATEPART(dw,@startdate) between 2 and 6
		Begin
		   Insert into @temptable(weekDays,Name) Values(@startdate,DATENAME (DW, @startdate))
		End
		SET @startdate = DATEADD(DAY,1,@startdate)
	 End
	 Return
End

Query to get weekdays

SELECT weekDays,Name from dbo.getWeekDays ('01/01/2016', '01/31/2016')
