Get day of week in SQL Server 2005/2008

datetime, sql, sql-server

Solution

Use `DATENAME` or `DATEPART`:

SELECT DATENAME(dw,GETDATE()) -- Friday
SELECT DATEPART(dw,GETDATE()) -- 6

Problem

If I have a date 01/01/2009, I want to find out what day it was e.g. Monday, Tuesday, etc... Is there a built-in function for this in SQL Server 2005/2008? Or do I need to use an auxiliary table?
