Somehow, after "user dfs.tmp", I was able to create view. But "describe" for view does not give much information. I was expecting "describe" command would give type definitions of fields " employee_id | full_name | first_name | last_name | position_id | position_title | store_id | depart ". But it does give a very generic field type.
