How To Get Year, Month and Day Out of DATETIME Values?

You can use DATEPART() to get any part of the DATETIME value. But to get year, month and day, you can use 3 specific functions: YEAR(), MONTH() and DAY(). These functions are equivalent to DATEPART() as:

YEAR(date) = DATENAME(year, date)
MONTH(date) = DATENAME(month, date)
DAY(date) = DATENAME(day, date)

In following tutorial example shows you how display a birth date in a format of yyyy.m.d:

SET @birth_date = '1987-05-19 16:10:41.403';
SELECT 'You were born on '
   + CONVERT(VARCHAR(10),YEAR(@birth_date))
   + '.'
   + CONVERT(VARCHAR(10),MONTH(@birth_date))
   + '.'
   + CONVERT(VARCHAR(10),DAY(@birth_date));
You were born on 1987.5.19
