I'm looking to compare two datasets that have just two variables each(Name & Num). Rather than return a listing of the differences between the datasets, what I'm after is a listing of identical obervations in the two datasets.
DATA ONE;
INPUT NAME NUM $ ;
CARDS;
FRED 1234
WILMA 4567
BARNEY 8369
BAMBAM 7894
;
RUN;
DATA TWO;
INPUT NAME NUM $ ;
CARDS;
FRED 1234
WILMA 8369
BETTY 7894
;
RUN;
PROC SORT DATA=ONE NODUPKEY;
BY NAME NUM;
RUN;
PROC SORT DATA=TWO NODUPKEY;
BY NAME NUM;
RUN;
DATA FINAL;
PROC COMPARE BASE=ONE COMPARE=TWO;
RUN;
OUTPUT:
I can't seem to find anything that will allow me to report on identical oberservations.
Any suggestions?
Thanks
First you'll likely get better results if Name is character.
Try this;
DATA ONE;
INPUT NAME $ NUM $ ;
CARDS;
FRED 1234
WILMA 4567
BARNEY 8369
BAMBAM 7894
;
RUN;
DATA TWO;
INPUT NAME $ NUM $ ;
CARDS;
FRED 1234
WILMA 8369
BETTY 7894
;
RUN;
PROC SORT DATA=ONE NODUPKEY;
BY NAME NUM;
RUN;
PROC SORT DATA=TWO NODUPKEY;
BY NAME NUM;
RUN;
data three;
merge one (in=inone)
two (in=intwo);
by name num;
if inone and intwo;
run;
Try DUPOUT= option in Proc Sort,
data _stack;
set one two;
run;
proc sort data=_stack dupout=_wanted_dup nodupkey;
by _all_;
run;
