Re: Age - Using Date of Birth and Today()

Hello,

I think that yrdif statement could be helpful. For example :

proc sql;

select employee_id, employee_name,  int(yrdif(emp_Hire_date,today(),"ACTUAL"))  as tenure,

       Salary,int(yrdif(Birth_date,today(),'ACTUAL')) as Age

       from arturo.salesstaff order by tenure desc;

SAS(R) 9.3 Functions and CALL Routines: Reference

Best regards

I would just point out with the above solution that it may not work on all events.  The documentation from SAS on the YRDIF function indicates to use the 'AGE' parameter rather than actual:

Personally I prefer to stick with an old tried and tested formula:

Either can be used replacing the text before as Age.
