Question

Suppose I have two Oracle databases. We’ll call them database A and database B.

Now suppose I have a table in database A that’s defined like this:

CREATE TABLE foo
(
    foo_id INT PRIMARY KEY,
    some_text VARCHAR2(10),
    other_table_id INT

    CONSTRAINT some_fk_constraint
        FOREIGN KEY (other_table_id)
        REFERENCES other_table(other_table_id)
)

…is there any easy way to create this same table in database B with the same primary key and same foreign key, but without any data? It would be ideal if there were a pure SQL method so I can do this in Python with cx_Oracle, but I can launch a shell script if need be.

DBMS_METADATA sounds like the package you’re looking for

select dbms_metadata.get_ddl('TABLE','DEPT','SCOTT') from dual;

Then you could run it with EXECUTE IMMEDIATE
