The DATEPART function accepts two parameters :

DATEPART ( datepart , date ) where
datepart - specifies the part of the date to return. For eg: year, month and so on
date - is the datetime or smalldatetime value

QUERY

SELECT
DATEPART(year, GETDATE()) as 'Year',
DATEPART(month,GETDATE()) as 'Month',
DATEPART(day,GETDATE()) as 'Day',
DATEPART(week,GETDATE()) as 'Week',
DATEPART(hour,GETDATE()) as 'Hour',
