I have data something like this -
id1 abc
id1 def
id2 pqr
id2 rst
------ etc
I want to have like this in output dataset -
id1 abc/def
id2 pqr/rst
thanks in advance,
Try this:
data have;
input id $ text $;
cards;
id1 abc
id1 def
id2 pqr
id2 rst
;
data want;
length alltext $30; /* Please adapt the length 30 to your needs! */
do until(last.id);
set have;
by id;
alltext=catx('/', alltext, text);
end;
drop text;
run;
proc print data=want;
var id alltext;
run;
If you want to have ID as the first variable in the dataset (and not only in the output), you can move the LENGTH statement after the SET statement, immediately before the assignment alltext=....
And if you don't understand the do loop before the SET statement here's another, old fashioned method. @FreelanceReinh solution is probably more efficient.
data want;
set have;
by id;
length var $100.;
retain var;
if first.id then call missing(var);
var=catx('/', var, text);
if last.id then output;
run;
proc print;run;
