    ****************************************************************

    * RECOMMENDATION:                                              *
    ****************************************************************
    SQLCODE -4742 RC1 will be issued when the query to be offloaded
    is a self-referencing INSERT with sub-select.
    
    For example,
    INSERT INTO   T1
    (SELECT * FROM T2 A
       WHERE C1 IN (3,2,3,4,5,6,7)
       AND NOT EXISTS (SELECT 1 FROM T1 B
                         WHERE A.C1=B.C1 )
       );
    
    In the above query, T1 is the INSERT target table, and it is
    also referenced in the sub-select. Thus, SQLCODE4742 RC1 will
    be issued.  PI29102 will fix this problem.
