Answer 1

you can do something like
select * from emp
where
'1000,2000,3000,4000,5000,6000,7000,8000,9950' like to_char(sal,'FM999999999990')||',%' or
'1000,2000,3000,4000,5000,6000,7000,8000,9950' like '%,'||to_char(sal,'FM999999999990')||',%' or
'1000,2000,3000,4000,5000,6000,7000,8000,9950' like '%,'||to_char(sal,'FM999999999990') or
'1000,2000,3000,4000,5000,6000,7000,8000,9950' = to_char(sal,'FM999999999990');
