Range_min

Minimum value of the archive range column

Information is output as the data type in the archive range column. Information is only output if there is an archive file that corresponds to a chunk (the data is stored in the chunk) whose ID is output in the Chunk_ID column.

  • If the archive file name is output in the Archive_file_name column

    The minimum value of the corresponding archive file's archive range column is output.

  • If nothing is output in the Archive_file_name column

    The minimum value of the archive range columns in all archive files that correspond to chunks whose ID is output in the Chunk_ID column is output.

Range_min_raw

Minimum value (hexadecimal) of the archive range column

Information is output as hexadecimal-format binary data only when the data type in the archive range column is CHARACTER. Information is only output if there is an archive file that corresponds to a chunk (the data is stored in the chunk) whose ID is output in the Chunk_ID column.
