How to find the dependency information for views?

Question

Hi All,
There is reuirement where in we have to find the dependency information for all the tables which are used in particular view...along with remote database connections.. For this we have tried to use following query..
Select * from user_dependencies
start with name =’SAMPLE_VIEW’
connect by prior trim(referenced_name)=trim(name);
The view consists of three tables :
Create view sample_view as
select t1.col1,
T2.col2,
T3.col3,
From
Table1,
Table2@prd1,
Table3@prd2
Where
T1.col5=t2.col5
And T1.col5=t3.col5;
But the ouptut is :
name     Type     Reference_name     Reference_type     Reference_link_name
sample_view     View     Table1     Table     null
So what will be the magic query which will give the all the tables in the view sample_view??
Desired result:
name     Type     Reference_name     Reference_type     Reference_link_name
sample_view     View     Table1     Table     null
sample_view     View     Table2     Table     prd1
sample_view     View     Table3     Table     prd2
Thanks all in Advance!!

Thanks all for the help!!
So right now, inorder to find the dependency informations for views there is no direct query :(
As per the michaels post, i have developed some query ....just joining the table....which will give the source code of the object... :)
The query is :
select view_name,db_link,owner, substr(to_char(text),instr(to_char(text),'.',1,2),instr(to_char(db_link),'@')) as _Final_result_,
substr(to_char(text),instr(to_char(text),'.',1,2),20),text from (
select a.view_name,b.owner,a.db_link,dbms_metadata.get_ddl ('VIEW', a.view_name) text
from (
select view_name, db_link
  from (select view_name, dbms_metadata.get_ddl ('VIEW', view_name) text
          from user_views ),
       user_db_links
where upper (text) like '%@' || nvl (substr (db_link, 1, instr (db_link, '.') - 1), db_link) || '%' ) A,
all_views B
where
A.view_name=b.view_name
and b.view_name='VW_TESTING') The sampe view is :
create or replace view VW_TESTING
as select A.F_DRUG_SKEY,B.F_DRUG_ID
from dma_info.MORE_SOME_FTF_DRUG@info A,dms_prf.MORE_SOME_FTF_DRUG_FACTOR@info B
where a.F_DRUG_ID=b.F_DRUG_ID and
rownum<=5 The output of these query is :
Final_result
MORE_SOME_FTF_DRUG@info A,dms_prf.MORE_SOME_FTF_DRUG_FACTOR@info B where .F_DRUG_ID=b.F_DRUG_ID and rownum<=5 In short through source code, I am trying to find those object name which are preceding the "@' sign...please let me know if this can be workaround for finding the dependencies of objects in view... :(
Thanks!!
