SAS function equivalent to EXCEL function iferror()

iank131 — Mon, 24 Nov 2014 08:01:26 GMT

Could someone tell me an equivalent SAS function for the EXCEL function iferror(), which I could use in a PROC SQL variable assignment.

For example, in an datastep if I have a SAS variable defined as:

AGE = YRDIF( birthdate, today(), 'ACTUAL');

but for some reason in my data the birthdate is missing, then I get an error. This does not stop SAS, but I would like it to put, for example, 22 (the average age) if the birthdate is missing. In a datastep I would write:

if missing(birthdate) then AGE = YRDIF( birthdate, today(), 'ACTUAL'); else AGE = 22;

However, in a PROC SQL, how would I do this? All I can think of is if there were an equivalent SAS function like the EXCEL iferror() function, then I could do this in one line. In other words, I would like to write the "equivalent" of (using the EXCEL function):

AGE = iferror( YRDIF( birthdate, today(), 'ACTUAL'), 22);

If the first argument is null or error, then the second argument is returned for AGE.

Thanks in advance.

Ian.

I would suggest you try the equivalent to Excel's "isblank" instead of "iserror". Could look like:

Data A;
Input Birthdate:Date9.; Format Birthdate Date9.;
Datalines;
01JAN2000
09SEP2006
.
;
Run;

Proc SQL;
Create Table B As
Select *,
Case When Missing (Birthdate) Then 22 Else
YrDif(Birthdate,Today(),'Actual') End As Age
From A;
Quit;

Thanks very much. I just happened to find almost exactly the same solution after searching some more. Thanks.

Here is a one line approach:

data have;

birthday='01jan2012'd;

output;

birthday=.;

output;

run;

proc sql;

create table WANT as

select *,

yrdif(COALESCE(BIRTHDAY,'15JUL1992'd),today(),'actual') as AGE

from HAVE;

quit;

So coalesce takes the first non-null value from the list, birthday first, then your default, and caluculates on that value.
