Calculate Age as on date

I have 3 sql tables

MProgram, MParticipant and MProgramParticipant. I want to add new calculated column ParticipantAgeAttended using ProgramStartDate from MProgram and DateOfBirth from MParticipant.


load
ProgramID,
ProgramCode,
ProgramStartDate;

SELECT
ProgramID,
ProgramCode,
ProgramStartDate
FROM xxxx.xxx.MProgram;

load
ParticipantID,
FirstName,
LastName,
DateOfBirth;

SELECT
ParticipantID,
FirstName,
LastName,
DateOfBirth
FROM xxxx.xxx.MParticipant;


LOAD ProgramCenterId as ProgramEventID,
ParticipantID,
age(ProgramStartDate,DateOfBirth) as ParticipantAgeAttended;

[MProgramParticipant]:
SELECT ProgramCenterId,
ParticipantID
FROM xxxx.xxx.MProgramParticipant;

Thanks. Just to clarify, we are merging all the 3 tables and then creating 4rth table which has calculated field. then dropping the big merged table. right?
