If you set both TVSTEMPERATURE and BLOCKCOMPRESSION values for a query band, unless the table setting for BLOCKCOMPRESSION is NEVER, the result is:

  • BLOCKCOMPRESSION determines the compression if the table setting is MANUAL.
  • TVSTEMPERATURE determines the compression if the table setting is AUTOTEMP.

If the setting for BLOCKCOMPRESSION is ALWAYS, the table is always compressed.
