SQL Query to return all the dependent objects

Question

Hi,
I have a question.
Suppose I am creating a table with a join on 10 other tables, views etc..
And there are nested sub-queries in the CREATE statement.
How can I get the list of all the dependent objects for that table without counting them manually.
I know, we can right click the table/view name and check the dependent objects in Toad or SQL Developer.
But, I want to know the SQL query for getting that information.
Thanks
Rajiv

Answer 1

well there is no way oracle would know what query was used when the table was created.
But here is one intuitive trick:
Step 1: Create a procedure that will have a cursor declared on the query you want to know what tables/views are used.
Step 2: Check USER_DEPENDENCIES to see what objects this procedure depends on
Let say you want to create TEST_A table using the following statement:
create table test_a
as
select *
from scott.emp,
     scott.dept;
  1  create or replace procedure test_temp
  2  as
  3  cursor test_cur is
  4             select *
  5             from scott.emp,
  6                  scott.dept;
  7  begin
  8     null;
  9* end;
