  • Closed as program error.

Error description

  • An index scan on a data partitioned table may trap or return in
    correct results if there were no available partitions when the
    scan was started, but a partition becomes visible (via a SET
    INTEGRITY command) before the scan completes.
    
    If there are no visible partitions when a partitioned index scan
    is started, the scan is expected to return no rows on fetch.
    Due to an error, if a data partition becomes visible during the
    scan,
     we will attempt to retrieve data and the wrong rows may be
    returned, predicates may be ignored, data rows may be returned
    out of order, or other unexpected errors may occur.
    
    If the index scan is using an index on expression, the attempt
    to retrieve data may trap.
    

Local fix

  • Run SET INTEGRITY on newly attached partitions before detaching
    the last existing partition, or run SET INTEGRITY with the ALLOW
    NO ACCESS option.
