Does anyone know how to calculate a persons age in proc sql using date of birth and todays function?

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;

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:

http://support.sas.com/documentation/cdl/en/lefunctionsref/63354/HTML/default/viewer.htm#p1pmmr2dtec32an1vbsqmm3abil5.htm

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

Either can be used replacing the text before as Age.
