I know that the following SQL code is used to get the second-lowest value overall from a table:
PROC SQL;
SELECT id, min (value)
FROM table_name
WHERE value NOT IN (SELECT min (value)
FROM table_name);
How can I modify the Sql code I have to achieve this? Or is there any other way to do this?

proc sort data=have out=want;
by id value;

data want;
set want;
by id;
if first.id then Marker=0;
Marker+1;
if marker = 2;
drop Marker;
run;
proc print data=want;

Don't use SQL. Use PROC SORT or PROC RANK.
