UPDATE statement is what you want/need.

[PGStats]

Use the self-update trick where every non-missing variable overwrites the previous value within a by group.

data have;
infile datalines missover dsd;
input name $ country $ salary;
datalines;
ganesh,, 40000
ganesh,india,  
Smith,USA,
Smith,,100000 
;

proc sort data=have; by name; run;

data want;
update have(obs=0) have;
by name;
run;

proc print; run;

To do this with SQL is not efficient:

proc sql;
select * 
from 
    (select unique name from have) 
    natural left join
    (select name, country from have where country is not missing)
    natural left join
    (select name, salary from have where salary is not missing);
quit;
