The day of the week can be retrieved in SQL Server by using the DatePart function. The value returned by function is between 1 (Sunday) and 7 (Saturday). To convert this to a string representing the day of the week, use a CASE statement.
Method 1:
Create function running following script:
CREATE FUNCTION dbo.udf_DayOfWeek(@dtDate DATETIME)
RETURNS VARCHAR(10)
AS
BEGIN
DECLARE @rtDayofWeek VARCHAR(10)
SELECT @rtDayofWeek = CASE DATEPART(weekday,@dtDate)
WHEN 1 THEN 'Sunday'
WHEN 2 THEN 'Monday'
WHEN 3 THEN 'Tuesday'
WHEN 4 THEN 'Wednesday'
WHEN 5 THEN 'Thursday'
WHEN 6 THEN 'Friday'
WHEN 7 THEN 'Saturday'
END
RETURN (@rtDayofWeek)
END
GO
Call this function like this:
SELECT dbo.udf_DayOfWeek(GETDATE()) AS DayOfWeek
ResultSet:
DayOfWeek
———-
Monday
Method 2: (This is update from comments I received below)
SELECT DATENAME(dw, GETDATE())

Time and Date only
SELECT CONVERT(VARCHAR(12), GETDATE(), 106)
SELECT CONVERT(VARCHAR(8), GETDATE(), 108)
@Nagarajan,
Note that all your TIME and DATEs are just VARCHARs
You should do this formation in the front end application
or
If you use SQL Server 2008, make use of new datatypes Time and Date

To get a deterministic value for the day of week for a given date you could use a combination of datepart and @@firstday. Otherwise your dependent on the settings on the server.
