Can anyone see my syntax error?

I get following message: Error validating the formula for column 'Age'.

(case when dayofyear([BirthDate]) < dayofyear(getdate()) then datediff(year,[BirthDate],getdate())-1 else  datediff(year,[BirthDate],getdate()) end)

Thanks,

DayOfYear is not a function (unless you wrote one). Use this definition for your computed column:

CASE
    WHEN DATEPART(dayofyear, BirthDate) < DATEPART(dayofyear, GETDATE())
         THEN DATEDIFF(YEAR, BirthDate, GETDATE()) - 1
    ELSE DATEDIFF(YEAR, BirthDate, GETDATE())
END

Open in new window

I separated it out for readability (and to verify it worked). Return it to one line or however you wish to lower-case it.

I presume dayofyear is a customer function, in which case you have to prefix it with the functions' owner name:

dbo.dayofyear(...)

Scott's approach is similar to dsacker's above, except he eliminated the repetition of the DATEDIFF by putting the CASE on the subtraction.

In other words, you can do this:
DATEDIFF(YEAR, BirthDate, GETDATE()) - CASE WHEN DATEPART(dayofyear, BirthDate) < DATEPART(dayofyear, GETDATE()) THEN  1 ELSE 0 END

dsacker,

Thanks for figuring out what I was trying to accomplish. Your syntax worked to solve the problem.

Sorry, to very one else for the poor presentation of my problem.
