    you cannot compare the content of CHUCK_DATA directly, because the datatype is 'long'.
    But as a workaround, you can convert the content to a string and then work with that string e.g.:

    ...where substr(T_CHUNK:CHUNK_DATA,1,5) < '10000'

    with (1,5) means building a string starting with the first character and a string length of 5 characters.

    Hope that helps,
