A table-specific disk I/O integrity checksum.

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

integrity_checking_level

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.
