If you have invoked a database, you have the necessary privileges
    to use the START_SEGMENTED_STRING statement.

    Starts a stream of segmented string segments within a record
    stream. Retrieving records with segmented string fields requires
    a kind of "segment stream" within a record stream. This second
    stream is normally established by nesting a special segmented
    string FOR loop inside another FOR loop. However, in certain
    cases, you cannot or may not want to use FOR loops (as in
    Callable RDO programs).

    The START_SEGMENTED_STRING statement is similar to the START_
    STREAM statement: it starts a "stream" of string segments. You
    do not use a FETCH statement to retrieve each segment. The PRINT
    or GET statement retrieves the segment and advances the pointer
    to the next segment. At the end of the stream, Oracle Rdb returns an
    end-of-stream message, SEGSTR_EOF.

    To end the stream, use the END_SEGMENTED_STREAM statement.
