Does anyone have a SQL function or statement they can share to calculate the current patient age from the birthdate?

Hi Doug,
Here is what we are using as a Scalar Function:
@EndDate as DATE = getdate -- Default is today's date (see below) but any date can be used here
-- IF DEFAULT VALUE (marked as 2999-01-01 as it doesn't accept functions) IS USED THEN USE TODAY'S DATE
IF @DOB >= @EndDate -- trap errors
SET @Result = 0
-- check if the person had its birthday in the specified year and calculate age
IF (MONTH(@EndDate)*100)+DAY(@EndDate) >= (MONTH(@DOB)*100)+DAY(@DOB)
SET @Result = DATEDIFF(Year,@DOB,@EndDate)
SET @Result = DATEDIFF(Year,@DOB,@EndDate)-1
RETURN @Result

Let me know if you have any questions.

Hi Doug,
I've attached a user-defined function you can use to calculate an age based on 2 dates of interest: the date of birth, and the "check date," which can be based on any datetime field in the DR (or current age, using the GETDATE system function.)
Let me know if you have any questions.

Tom Harlan of my staff did a session at MUSE called "Z meets SQL" and showed SQL equivalents of most of the Z library that is useful in reporting. Some were done with sql code and some were done as procedures.
The link to the powerpoint and the Sql code is here:
The sql code to look at is in MUSE2015-IatricGetAge.sql
The function returns months/days or years/months if age is under 6 years, just like the Z program does.
