                                of byte   this sequence.
                                varying
    RDB$DESCRIPTION             list      Description provided for
                                of byte   this sequence.
                                varying
    RDB$START_VALUE             bigint    Starting value for the
                                          sequence.
    RDB$MINIMUM_SEQUENCE        bigint    Minimum value for the
                                          sequence.
    RDB$MAXIMUM_SEQUENCE        bigint    Maximum value for the
                                          sequence.
    RDB$NEXT_SEQUENCE_          bigint    Next value available for
    VALUE                                 use for the sequence.
                                          This column is a read
                                          only COMPUTED BY column.
                                          When the sequence is first
                                          defined this column returns
                                          NULL.
    RDB$INCREMENT_VALUE         integer   Increment value for the
                                          sequence. A positive
                                          value indicates an
                                          ascending sequence, and
                                          a negative value indicates
                                          a descending sequence.
    RDB$CACHE_SIZE              integer   Number of sequence numbers
                                          to allocate and hold in
                                          memory. If one (1), then
                                          NOCACHE was specified
                                          and the values will be
                                          allocated one at a time.

                                          this sequence object. This
                                          value is for internal use
                                          only.
