Update-data-set correct syntax

I ran the describe-dataset command line and got the output. Now, I want to use API to update- dataset.
What should be the correct syntax for these parameters? I am getting error especially about physical-table-map.

–aws-account-id
–data-set-id
–name
–physical-table-map
–import-mode

I think, make sure the DB table is exists on target.
