You can only specify this option for columns or column partitions of a column-partitioned table. Teradata Database applies autocompression for a physical row on a per container basis. For efficiency, the system may use the autocompression method chosen for the previous container, including not using autocompression, if that is more effective.

If you do not specify AUTO COMPRESS or NO AUTO COMPRESS, Teradata Database uses the value of the cost profile constant AutoCompressDefault to determine whether to default to autocompression or not. For more information about AutoCompressDefault, see SQL Request and Transaction Processing, B035-1142.

AUTO COMPRESS
Apply auto compression to values inserted into this column partition.
NO AUTO COMPRESS
Do not apply auto compression to values inserted into this column partition.
