I am trying to write a macro to concatenate all values of a row. But its not working. can some one point out? Without the macro its working fine.
%macro dummy(var=);
proc sql;
create table values as select distinct(&var.) as vals from td;
run;
data values1;
length new_val $100.;
%do %until(eof);
set values end=eof;
new_val=catx("",new_val,vals);
%end;
run;
proc print data=values1;
run;
%mend;
%dummy(var=job);
When you say all values of a row do you mean the values in a row or column?
If a column, look at PROC SQL documentation on calculating macro variables.
If a row, try CATX(', ', of _all_);
Yes, macro language doesn't understand DATA step variables such as eof.
You seem to understand the right tools, why not use them:
proc sql;
select strip(var) into : vals separated by ',';
Or possible (but different):
select distinct strip(var) into : vals separated by ',';
If you really want this as a DATA step variable (although it is difficult to envision why), you could use:
data test;
longvar = "&vals";
run;
