Primary Keys Issue on Remote Tables

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.

It woulddepend how you "copy". Export/Import will be default, though it has options not to. So how did you do the copy?

By doing
Create Table as select * from
[where 1 = 2 -- optional]
Now need to copy constraints but i cannot edit remote tables or i cannot apply Triggers or views on those tables. So any other way around

You can create a table, but you can't create triggers or constraints on it, or create views?

Sorry look like u took me wrong...
I can only view the contents of that schema and can make copies of his schema structure thats all.

No, and no.

hmmm....William you just said no and no...But can you give me idea how to do it..Help from any bosy will be really appreciated

Try

DBMS_METADATA.GET_DDL@remotedb(objecttype, name);

e.g.

DBMS_METADATA.GET_DDL@remotedb('TABLE','EMPLOYEES');

This is a function that you can use in either a plain SQL query or in PL/SQL. It will return the SQL to create the table, including constraints.
