Retrieve next record

Question

Hi there,
I have a query where I pass in a VARCHAR2 (CIPIDI_NR). This Query should return the next higher (or lower) record depending on some conditions. I tried:
select * from TBL_CIPIDI
where confidential_flag = 0
and CIPIDI_NR > (THIS IS WHERE I PASS IN THE VALUE)
Unfortunately this returns all records which are higher than the VALUE I pass in. But I only would like to receive the next record. I am not using a sequence. How would be the best way to approach this.
Thanks a lot
Chris

-- correction: I left out the confidential_flag = 0 in the subquery:
select *
from   TBL_CIPIDI
where  confidential_flag = 0
and    CIPIDI_NR =
       (SELECT MIN (cipidi_nr)
        FROM   tbl_cipidi
        WHERE  confidential_flag = 0
        AND    cipidi_nr > (PASSED IN VALUE))
