Finding someone's age in SQL

Question

In a SQL Server database, I record people\'s date of birth. Is there an straight-forward method of working out the person\'s age on a given date using SQL only?

Check out this article: How to calculate age of a person using SQL codes

Here is the code from the article:

DECLARE @BirthDate DATETIME
DECLARE @CurrentDate DATETIME

SELECT @CurrentDate = '20070210', @BirthDate = '19790519'

SELECT DATEDIFF(YY, @BirthDate, @CurrentDate) - CASE WHEN( (MONTH(@BirthDate)*100 + DAY(@BirthDate)) > (MONTH(@CurrentDate)*100 + DAY(@CurrentDate)) ) THEN 1 ELSE 0 END
