Extract ddl for a table without its integrity contraints

dbms_metadata.set_transform_param(dbms_metadata.session_transform, 'REF_CONSTRAINTS', FALSE);

then extract the ddl using one of the methods above.
Finally, extract the constraint ddl and run it separately:

DBMS_METADATA.GET_DDL('REF_CONSTRAINT','<REF_CONS_NAME>');
