Greetings listers,

Ever worry about wrinkles, loss of hair, and bad breath?

Well, the following script can't help you with THAT, but it CAN show you a heirarchical list of objects that depend upon the given object! Just pass in &1=owner and &2=object name, and viola! No more changing objects without knowing what depends on them
(and might break). (The reason for the temp table is
that you can't do recursive self-join sql on complex views.) This can be a very useful script if you make production database changes.

prompt
prompt objects depending on &1. &2:
prompt

set termout off
set head off
set verify off

drop table depends;

create table depends as select * from
sys.dba_dependencies;

set termout on

select '*'||lpad(' ',level+3)||type||'
'||owner||'.'||name
from depends
connect by prior owner = referenced_owner and prior name = referenced_name
and prior type = referenced_type
start with referenced_owner = upper('&1') and referenced_name = upper('&2')
and owner is not null
/

good luck,

jack silvey
