"Qualifier" means the table alias used before the column's
name. Just write the name of the column without specifying
its table because the optimizer will know what table to
look for this column.

Hi guys, I have four tables those are emp,dept,eliminate and uneliminate. i wrote small cursor..when i run, it display one error (ORA-01403 nodata found)... The query is: Declare cursor c1 is select e.ename emp_name from emp e,dept d where e.deptno=d.deptno group by deptno; r1 c1%rowtype; test_emp varchar2(200); begin for r1 in c1 loop begin select eliminate_emp into test_emp from eliminate t,uneliminate ut where t.number=ut.number and t.deptno=e.deptno and rownum<1; end; dbms_output.put_line(r1.emp_name); end loop; end; Thanks...
