Manual export views

[tmp]

Not absolutely I understand.
Table USER_VIEWS contain text view and name view but not contain parametrs view!!!
Whether is what or a way to receive these parameters?

CREATE OR REPLACE VIEW KLMN
!!!(FULLNAME, UPDATEDT)!!!
AS
SELECT NAMES.FULLNAME, NAMES.UPDATEDT
FROM NAMES;

[tmp]

I at all have not understood what for there these parameters and without them all works...
Sorry!!
