You name indexes in the CREATE INDEX statement. In CREATE INDEX
    and other SQL statements, the names you give to indexes can be
    qualified by authorization identifiers.

                                   NOTE

       In syntax diagrams, the index-name syntax element refers to
       either the qualified or unqualified form of the name given
       to the index in the CREATE INDEX statement.
