How to Process multiple prompt values generated from SAS stored process.

Sujeet — Thu, 12 Apr 2018 07:54:03 GMT

Hello guys.
I am working on sas Stored process.
where i need to process multiple values from single prompt.
For example,
prompt name = Brand.
after selecting multiple values (for now assume 4 values)it auto creates variables &Brand_count, &Brand1,&Brand2,&Brand3,&Brand4.
so to use these prompt values I implement these prompts (&Brand1,&Brand2,&Brand3,&Brand4) in code.
The code runs nicely if I give exactly 4 values,
but after passing values more or less than 4 (let's say 3 or 5 values)
then it gives error.
If someone facing the same issue or have solution .please help me.

i am working on SAS enterprise guide 7.1

Thanks...

It is difficult to guess what was the programmer intention.

As the prgram is stored, I suspect if you have the source.

If the program requires 4 values. try enter '*' as dummy value.

I guess you need to do everything in a loop:

%do i = 1 %to &brandcount;

and use indirect addressing like

&&brand&i

But that's all guesswork without seeing the code.

Hi , Shmuel,

I tried dummy values. but only first value from multiple values is accepted while execution.

and also tried to use IF ELSE but it does not work.

%if &BRAND_COUNT=2 %then 
                            "&brand2";
             %else %do i=1 %to &BRAND_COUNT;
                         "&&brand&i"
             %end; 
               
    quit;

See a simple example for building an in-list in SQL:

%let namecount=3;
%let name1=Alfred;
%let name2=Joyce;
%let name3=Robert;

%macro select_from_prompt;
proc sql;
create table want as
select * from sashelp.class
where name in (
%do i = 1 %to &namecount;
  %if &i > 1 %then ,;
  "&&name&i"
%end;
);
quit;
%mend;
%select_from_prompt

Hi Kurt ,

thank you.

you are right . Looping the values is the only way i can see now.

your example is very useful.

now i am experimenting with your example .

let's see if it works
