Answer 1

if ur question is getting the last row of a table then try this query instead
select * from emp where rowid in
(select rowid from emp where rownum<=(select count(*) from emp))
and rowid not in (select rowid from emp
where rownum<=(select (count(*)-1) from emp));
the above query will certainly return a single row and then u can if(rs.next()) and then extract the contents from the resultset....
