This seems to work




DECLARE @DOB DATETIME

SET @DOB='9/19/2000'


SELECT FLOOR(DATEDIFF(DD,@DOB,GETDATE())/365.25)

Good try but it doesn't work...

DECLARE @DOB DATETIME

SET @DOB='01/01/2013'

SELECT FLOOR(DATEDIFF(DD,@DOB,'01/01/2014')/365.25)

RBAR is pronounced ree-bar and is a Modenism for Row-By-Agonizing-Row.
First step towards the paradigm shift of writing Set Based code:
Stop thinking about what you want to do to a row... think, instead, of what you want to do to a column.
If you think its expensive to hire a professional to do the job, wait until you hire an amateur. -- Red Adair

But they wouldn't be 1 until after their BDay
or you could just

DECLARE @DOB DATETIME

SET @DOB='01/01/2013'

SELECT FLOOR((DATEDIFF(DD,@DOB,'01/01/2014')+1)/365.25)

Still doesn't work. Last I heard, you gained a year on your birthday and not the day before (Feb 29 babies sometimes excluded). :-)

DECLARE @DOB DATETIME

SET @DOB='01/01/2012'

SELECT FLOOR((DATEDIFF(DD,@DOB,'12/31/2012')+1)/365.25)
