  • ****************************************************************
    * USERS AFFECTED: All DB2 10 for z/OS users of an SQL          *
    *                 statement with an IN list predicate, which   *
    *                 contains host variables mixed with string    *
    *                 constants.                                   *

    *                      DSNXGRDS DSNXRSIN OFFSET10D4 could      *
    *                      happen for an SQL statement with an IN  *

    *                      when parallelism is enabled.            *

    ****************************************************************
    ABEND0C4 RC00000010 at the location DSNXGRDS DSNXRSIN OFFSET10D4
    could happen for an SQL statement with an IN list predicate,
    which contains host variables mixed with string constants, when
    parallelism is enabled.
    
    An example is shown below:
    
    SELECT 1
    FROM T1
    WHERE T1.C1 IN ('Lit1', :HV1, 'Lit2');
    
    DB2 did not correctly process the aforementioned SQL statement,
    which caused the ABEND.
    
    The IN list predicate can be transformed from a few OR
    predicates, like C1 = 'Lit1' OR C1 = :HV1 OR C1 = 'Lit2' will
    be transformed into C1 IN ('Lit1', :HV1, 'Lit2').
    

Problem conclusion

  • DB2 has been modified to correctly process the aforementioned
    SQL statement, so there will be no the ABEND.
