Answer / venkatesh
if you use x=1 and y=0
you must use set statement also
try this
data a b;
merge one two;
by id;
if x=1 and y=1 then output a;
if x=1 and y=0 then output b;
data new;
set a b;
run;

There is no such Inner & Left Joins. In SAS only one join
i.e Right Join. If you want Left Join you have to use the
data set in the second place. For example: D1 D2 are the
data sets for D2 you want to make, UPDATE D1 D2;
