Just bumped on this:
DECLARE @dob datetime
SET @dob='1992-01-09 00:00:00'
SELECT DATEDIFF(YEAR, '0:0', getdate()-@dob)
Works ok. Who can explain '0:0' ?
Actually it doesn't really work ok. See the posts on the first page.
However, the '0:0' is simply a strange way of writing 1/1/1900 or the 0 date. Remember the second parameter is a datetime so it will perform an implicit conversion.
select cast('0:0' as datetime)
