A table-specific disk I/O integrity checksum. Specifies the integrity checking level.

The checksum setting applies to primary data rows, fallback data rows, and all secondary index rows for the table.

If you do not specify a value, then the system assumes the system-wide default value for this table type. This is equivalent to specifying DEFAULT.

If you are changing the checksum for this table to the system-wide default value, then specify DEFAULT.

ON
Calculate checksums using the entire disk block. Sample 100% of the disk blocks to generate a checksum.
OFF
Disables checksum disk I/O integrity checks.
DEFAULT
The default setting is the current DBS Control checksum setting specified for this table type.
