imagine first table s_dept with
id = primary key
name = foreign key
region = foreign key
second table dept_1
id= primary key
name = varchar2
region=varchar2
so dept_1 fills s_dept with name and region
So i know that some parts of oracle dictionary show the constraint into tables. I would like to see the constraint of s_dept linked with dept_1

try this query
select u1.constraint_name,u1.constraint_type,u2.table_name
from user_constraints u1,
user_constraints u2
where u1.table_name='EMP'
and u2.constraint_name=u1.r_constraint_name
and u1.constraint_type='R'
also use the user_cons_columns
