What if the syntax was something like -

CREATE TABLE tabname (
     ...
     ...
  ) PARTITION BY
  HASH(expr)
| RANGE(expr)
| LIST(expr)
[PARTITIONS num_partitions] /* will apply to HASH only for now*/
[PARTITION partition_name CHECK(...) [USING TABLESPACE tblspcname],
  PARTITION partition_name CHECK(...) [USING TABLESPACE tblspcname]
  ...
];


And (if we use the ALTER TABLE to add partitions)

ALTER TABLE tabname
ADD PARTITION partition_name CHECK(...)
[USING TABLESPACE tblspcname];


We could as well drop the USING part.

Regards,
Nikhils
