Macro variable not resolved

sasecn — Tue, 18 Feb 2020 19:03:20 GMT

I tried to used macro variables to create subsets from a large table. The example is to subset sashelp.cars into 3 tables by variable: Origin. The code was working in the past, at least worked in Nov. 2019. But now I got the error meassage:

WARNING: Apparent symbolic reference C not resolved.
ERROR: A character operand was found in the %EVAL function or %IF condition where a numeric operand is required. The condition was:
&c
ERROR: The %TO value of the %DO I loop is invalid.
ERROR: The macro T will stop executing.

I think it is because macro variable C was not resolved, but i could be wrong. Any help would be great, thanks!

proc sql;
create table test as
select distinct origin, count(distinct origin) into :origin1-, :c
from sashelp.cars
;
quit;

%macro t;
proc sql;
%do i=1 %to &c;
create table &&origin&i as
select origin
from sashelp.cars
where origin="&&origin&i";
%end;
quit;
%mend t;

%t

Post the log and error. Make sure to have set the macro debugging options before running the code and then post the log with that extra information, if you don't figure it out from there.

options mprint symbolgen;

HI @sasecn You can't CREATE TABLE when using INTO clause

Try the corrected below


proc sql;
select distinct origin, count(distinct origin) into :origin1-,  :c
from sashelp.cars
;
quit;

%put &=c;

%macro t;
proc sql;
%do i=1 %to &c;
create table &&origin&i as
select origin
from sashelp.cars
where origin="&&origin&i";
%end;
quit;
%mend t;

%t

Well, the issue pretty much jumps out:

24 proc sql;
25 create table test as
26 select distinct origin, count(distinct origin) into rigin1-, :c
27 from sashelp.cars
28 ;
WARNING: INTO clause is ignored in the CREATE TABLE statement.
NOTE: The query requires remerging summary statistics back with the original data.
NOTE: Table WORK.TEST created, with 3 rows and 2 columns.

Why are you creating a table if you only need macro variables? Try removing the CREATE TABLE portion and see what happens.

Thanks for your reply! NOVINOSRIN also point this out. I think that is the problem.

The log tells you this is the problem.

Remove the CREATE TABLE part. Add the NOPRINT option to avoid cluttering your output with the list of values. No need to count, SAS will count for you into the SQLOBS macro variable. You can save the value into another macro variable if you want.

proc sql noprint;
select distinct origin into :origin1-
from sashelp.cars
;
%let c=&sqlobs;
quit;
