Hello experts,

I have a need to display the customer's age in years.  The field in the database is person.date_of_birth, and is an 8 character varchar that stores Date of Birth as yyyymmdd.

What is the best way to display the current age?

Something like:

DateDiff("yyyymmdd", CDate({person.date_of_birth}), CurrentDate ), 0) + " yrs"

Thoughts?

Thanks!

-- Here is a straight SQL approach - you would substitute the DOB column name for @bd in the query:

declare @bd varchar(10)
select  @bd = '2008-02-21'

select datediff(yy,@bd,getdate())
  - case when month(@bd)>month(getdate()) then 1 else 0 end
  - case when month(@bd)=month(getdate()) and day(@bd)>day(getdate()) then 1 else 0 end
as Age
0

I have a presentation that that discusses not only the most commonly used methods for calculating age accurate, but also demonstrating how they're wrong most of the time. The presentation also demonstrates how to accurately calculate age with both a formula and a SQL Expression.  The problem with using a formula is that, while accurate, it can't be used efficiently within the record selection criteria - if you need to filter a report against people aged 5 - 10, for example, the formula won't be processed on the database.  That's where the SQL Expression comes in.
