Mike,

Add a GROUP BY command:

select distinct (rpad(employee_id,6,' ')) ||';'|| ssn from EMP
group by (rpad(employee_id,6,' ')) ||';'|| ssn

Hope this helps.

I have problem to use "distinct" with Function on select statement. Can anyone give me a hint?

Thanks.

SQL> select distinct (rpad(employee_id,6,' ')) ||';'|| ssn from EMP
2 order by employee_id;
select distinct (rpad(employee_id,6,' ')) ||';'|| ssn from EMP
