System_Relations

    Nosystem_Relations

    The System_Relations qualifier specifies that optimizer
    statistics are to be displayed for system tables (relations)
    and their associated indexes.

    If you do not specify the System_Relations qualifier, or if you
    specify the Nosystem_Relations qualifier, optimizer statistics
    are not displayed for system tables or their associated indexes.

    Specify the Noindex qualifier if you do not want statistics
    displayed for indexes defined on the system tables.

    The default is the Nosystem_Relations qualifier.
