oracle - Execute sql-statement once at date x -

-

i want have sql update-statement executed once @ date x. how can achieve on oracle 10g database?

edit:
aim fire update statement every day. why? have tiny mistake in application, can 'temporarily fixed' statement (since have db-access till real fix happen).

consider dbms_scheduler. meant running jobs periodically, can set pl/sql job script suspend or cancel job entry after run-once job ends successfully.
