    For example, in the following statement, the condition "b>0" is

    * PROBLEM DESCRIPTION:                                         *
    * IBM solidDB server can shut down abnormally when a query     *
    * that has a redundant WHERE condition is executed.            *
    *                                                              *
    * For example, in the following statement, the condition "b>0" *
    * is redundant:                                                *
    * SELECT * FROM a WHERE (b >0) AND (b IN (1,2))                *
    *                                                              *
    * This problem was caused because all data structures were not *
    * correctly initialized.                                       *
    ****************************************************************
    * RECOMMENDATION:                                              *
    * Upgrade to IBM solidDB 6.5 Interim Fix 6.                    *
    ****************************************************************

  • Fix is included in IBM solidDB 6.5 Interim Fix 6. Queries with
    redundant WHERE queries can now be executed.
