I want to create the separate datasets for each location, when number of locations are not specified

[Kusuma001]

Question:

if user dont know how many locations are there in input, then how can we write a code in SAS

Task :

data one;

input emp_id  name$ loc$;

datalines;

1 srinivas bang

2 sudhakar bang

3 qqqq hyd

4 hhhh hyd

5 bhanu mumbai

6 jjjjj mumbai

;

run;

Solution:;

DATA Bang;

 set one(where=(loc='bang'));

run;

DATA Hyd;

 set one(where=(loc='hyd'));

run;

DATA Mumbai;

 set one(where=(loc='mumbai'));

run;

If you search 'split data into subsets' you'll find many solutions. Note that this is rarely recommended in SAS

If you dont know how any locations are in your data step, this HASH object solution works well.

data one;
input emp_id  name$ loc$;
datalines;
1 srinivas bang
2 sudhakar bang
3 qqqq hyd
4 hhhh hyd
5 bhanu mumbai
6 jjjjj mumbai
;

proc sort data=one;
   by loc;
run;

data _null_;
   if _n_=1 then do;
   if 0 then set one;
   declare hash h(dataset:"one(obs=0)", multidata:'y');
      h.definekey(all:'y');
      h.definedata(all:'y');
      h.definedone();
   end;
   do until(last.loc);
      set one;
      by loc;
      h.add();
   end;
   h.output(dataset:loc);
   h.clear();
run;
