SAS Select Into Dynamic Naming - select

Question

I am trying to use SAS proc sql select into for 8 different scenarios.
%MACRO Loop();
proc sql;
%do i=1 %to 8;
select total_value
into :Sol_&i. separated by ','
from Master.adjusted_hours
where Solicitation = "&i.";
%end;
quit;
%mend;
%Loop();
However when I use the %put function, the macro variable isn't recognized. The error is "Apparent symbolic reference SOL_1 not resolved."
%put &Sol_1;
How can I store the value in this macro variable and call it later in the code?

Answer 1

You need to declare SOL_1 SOL_2, etc as global macro variables. I wasn't sure what was in your data, so I created some dummy data.
%global SOL_1 SOL_2 SOL_3 SOL_4 SOL_5 SOL_6 SOL_7 SOL_8;
data adjusted_hours;
do x = 1 to 8;
solicitation=put(x, 1.);
do total_value = 1 to 10;
output;
end;
end;
drop x;
run;
%MACRO Loop();
proc sql noprint;
%do i = 1 %to 8;
select total_value
into : Sol_&i. separated by ','
from adjusted_hours
where Solicitation = "&i.";
%end;
quit;
%mend;
%Loop();
%put _USER_;
Partial log:
GLOBAL SOL_1 1,2,3,4,5,6,7,8,9,10
GLOBAL SOL_2 1,2,3,4,5,6,7,8,9,10
GLOBAL SOL_3 1,2,3,4,5,6,7,8,9,10
GLOBAL SOL_4 1,2,3,4,5,6,7,8,9,10
GLOBAL SOL_5 1,2,3,4,5,6,7,8,9,10
GLOBAL SOL_6 1,2,3,4,5,6,7,8,9,10
GLOBAL SOL_7 1,2,3,4,5,6,7,8,9,10
GLOBAL SOL_8 1,2,3,4,5,6,7,8,9,10
If you want to avoid the macro altogether and having to declare the %global variables, here's a data step solution that will work as long as your dataset is sorted by Solicitation.
data _null_;
set adjusted_hours;
by solicitation;
format temp $50.;
retain temp ;
temp=CATX(',',temp, total_value);
if last.solicitation then do;
call symputx(CATS('SOL_', solicitation), temp);
call missing(temp);
end;
run;
