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.
Although they tell us that they want it real bad, our primary goal is to ensure that we dont actually give it to them that way.
Although change is inevitable, change for the better is not.
Just because you can do something in PowerShell, doesnt mean you should. Wink

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)
