Hi
When combining two data sets with the same variables using Data/Merge and a By statement, the records that don't match on the variables in the By statement are just appended to the data set?
Paul
data want;
merge have(in=a) have1(in=b);
by id;
if a and b;
run;
That will get me only those records in both record sets, I am presuming?
The below will get me the records that match on Id overlaying each other and will append those that don't?
data combine;
merge first second;
by Id;
run;
Paul
Yes, that is correct. I thought you don't want to see obs that are not contributing in merge.
