    Description

      Today, we only have the option to checksum a table:

      CHECKSUM TABLE tbl_name [, tbl_name] ... [ QUICK | EXTENDED ]

      However, it would be useful to be able to specify a subset of data, especially a single partition.

      Additionally, it would be best if it would be possible to get a checksum of data in an un-partitioned table, then copy this data into a partitioned table, aggregate the checksum values of each partition, and get the same value as un-partitioned table.
