Hi @BrahmanandaRao 

Here is an approach to do this:

proc sql;
	create table want as
	select id, max(salary) as max2
	from (select * from req group by id having salary < max(salary))
	group by id;
quit;

I am not sure whether you can use the largest() function in proc sql.

[ed_sas_member · Accepted solution]

Another approach could be:

proc sort data=req;
	by id;
run;

proc transpose data=req out=req_tr prefix=salary;
	var salary;
	by id;
run;

data want;
	set req_tr;
	max2 = largest(2,of salary:);
	keep id max2;
run;

[BrahmanandaRao]

data want;
	set req_tr;
	max2 = largest(2,of salary:);
	keep id max2;
run;

You only want SQL ?

data req;
input id$ salary;
datalines;
001 2000
002 3000
003 4000
001 3000
001 5000
004 2000
003 1000
002 5000
004 1000
;

proc sql;
select distinct a.*
 from req as a,req as b
  where a.id=b.id and a.salary<b.salary 
   group by a.id,a.salary 
    having count(*)=1;
quit;
