have this query where i can check what are the primary keys on remote table.

select column_name from all_cons_columns where table_name='EMPLOYEES' and owner='BRENDAN';
COLUMNS_NAME
*************************
EMPLOYEE_ID

Now Question is

1. When we do copy tables does that also copy Primary keys because when i run the same query after copying tables it does not show any rows e,g,

select column_name from all_cons_columns where table_name='EMPLOYEES_COPY' and owner='TEST'

2. When we do copy does that also copy constraints?

Any help will be really appreciated.
