How To Get Year, Month and Day Out of DATETIME Values in SQL Server Transact-SQL?

✍: FYIcenter.com

A

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:

DECLARE @birth_date DATETIME;
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));
GO
You were born on 1987.5.19
