Hi i have 3 tables called one two and three (in realtime i have around 40 to 50 different tables)
i have to summarize these tables based on the ID as the key variable , like ID 3 is in all the table with different dept name, so in the final summarized table the dept for Id 3 should be all the 3 dept separated by a comma (,)
data i have below
data one;
input id dept$;
cards;
1 del
2 mum
3 bang
;
run;
data two;
input id dept$;
cards;
3 bbsr
4 cal
;
run;
data three;
input id dept$;
cards;
5 pun
3 hyd
6 che
;
run;
data i want :
id | dept |
1 | del |
2 | mum |
3 | bang ,Hyd ,bbsr |
4 | cal |
5 | pun |
6 | che |
That would happen if you leave out the statement:
if last.id;
If you do have further issues, be sure to post the log.
since no duplicates,
1. do a one to one merge
2. catx with delim
3. keep the vars you want in final and you are done
Here's an illustration of two different methods:
*create sample data for demonstration;
data have;
infile cards dlm='09'x;
input OrgID Product $ States $;
cards;
1 football DC
1 football VA
1 football MD
2 football CA
3 football NV
3 football CA
;
run;
*Sort - required for both options;
proc sort data=have;
by orgID;
run;
**********************************************************************;
*Use RETAIN and BY group processing to combine the information;
**********************************************************************;
data want_option1;
set have;
by orgID;
length combined $100.;
retain combined;
if first.orgID then
combined=states;
else
combined=catx(', ', combined, states);
if last.orgID then
output;
run;
**********************************************************************;
*Transpose it to a wide format and then combine into a single field;
**********************************************************************;
proc transpose data=have out=wide prefix=state_;
by orgID;
var states;
run;
data want_option2;
set wide;
length combined $100.;
combined=catx(', ', of state_:);
run;

First, sort all three data sets by ID.
I'm not sure why you want Hyd as the middle value instead of the last value (or if that is just a mistake).
After sorting, you could use:
data want;
set one two three;
by id;
length all_depts $ 100;
if first.id then all_depts = dept;
else all_depts = catx(', ', all_depts, dept);
if last.id;
drop dept;
run;
Notice that you need a new, longer variable to hold the full set of characters. If you want to, you could add this as the final statement (before the run statement):
rename all_depts = dept;
If you really want Hyd as the middle value you would need to change the SET statement:
set one three two;
Finally, note that this is probably a bad idea. The vast majority of the time it will be easier to use the data in its original form.
@Astounding i tried the code , its giving the output like below , but we need the 5th observation only for Id 3 (i.e 3 bang,bbsr,hyd)
please suggest
also as there are many datasets so i am appendeing all the datsets , then sort it by Id and then i am applying the code
1 del
2 mum
3 bang
3 bang,bbsr
3 bang,bbsr,hyd
4 cal
5 pun
6 che
That would happen if you leave out the statement:
if last.id;
If you do have further issues, be sure to post the log.
