I have a 5.5 million row table that has the dateofbirth as a short date. The format looks like 1946-09-20.
I am trying to calculate the age using a SQL query but am having issues in SQL Server with errors. I have tried datediff and dateadd but nothing works.

What is the column specification for the date?

MM

select geometry::STGeomFromWKB(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

Do you have errors in your calculations (getting incorrect age) or errors thrown by SQL Server that might come from incorrect data?

You can use the function on the link below to calculate Age using @START_DATE = birthdate and @END_DATE = today.

Age Function F_AGE_IN_YEARS

It's been a while since I'd use or suggest a scalar function as a solution to a problem.

Instead, this should do it.

SELECT dob,

CASE WHEN DATEADD(YYYY, DATEDIFF(YYYY, dob, GETDATE()), dob) > GETDATE()

THEN DATEDIFF(YYYY, dob, GETDATE()) - 1

ELSE DATEDIFF(YYYY, dob, GETDATE())

END

FROM (VALUES(CAST('19851115' as date)), ('19850131'), ('19850302'), ('19840302'))x(dob) --Sample dates
