SYSTEM.PARAMETER contains information about parameters that may be
passed to and from procedures.
SYSTEM.PARAMETER is
initially empty, and it is updated whenever ALLBASE/SQL
processes a CREATE PROCEDURE, DROP PROCEDURE, or
TRANSFER OWNERSHIP statement for a procedure that includes
parameters. If a TRANSFER OWNERSHIP is done on the procedure, the owner field
in this view is updated with the Name of the new owner. Table 8-21 System.Parameter |
