Try mergin via an sql statement, since it contemplates all possible
combinations (rather than looking for single entries in one of the sets)?
The following:
proc sql;create table sortie as
select a.id,fruit,color from one as a ,two as b
where a.id=b.id;quit;
does it.

Subject: Question on merge with duplicate keys
Dear SAS-L,
I have a question when performing a merge of two datasets
which have duplicate keys:
DATA one;
INPUT id $ fruit $;
CARDS;
1 N
1 Y
2 N
2 Y
3 N
;
RUN;
PROC SORT data=one;
BY id;
RUN;
DATA two;
INPUT id $ color $;
CARDS;
1 100
2 50
2 20
3 80
;
RUN;
PROC SORT data=two;
BY id;
RUN;
DATA final;
merge one two;
BY id;
RUN;
The result of the above merge is:
1 N 100
1 Y 100
2 N 50
2 Y 20
3 N 80
However the desired output from a merge between dataset 'one' and 'two'
that I am looking for is the following:
1 N 100
1 Y 100
2 N 50
2 N 20
2 Y 50
2 Y 20
3 N 80
I would be grateful for any suggestions as to how I can obtain the above
result.
Cheers,
Oliver
