DATEPART(datepart,date)

Where date is a valid date expression and datepart can be one of the following:

datepart	Abbreviation
year	yy, yyyy

dayofyear	dy, y
day	dd, d

Example

Assume we have the following "Orders" table:

OrderId	ProductName	OrderDate
1	Jarlsberg Cheese	2014-11-22 13:23:44.657

The following SELECT statement:

SELECT DATEPART(yyyy,OrderDate) AS OrderYear,
DATEPART(mm,OrderDate) AS OrderMonth,
DATEPART(dd,OrderDate) AS OrderDay
FROM Orders
WHERE OrderId=1

will result in this:

OrderYear	OrderMonth	OrderDay
2014	11	22
