Script per trovare le dipendenze multilivello di un pacchetto

Puoi utilizzare una connessione tramite su user_dependencies per la maggior parte dei casi.

Determinazione delle dipendenze

Esempio che funziona per qualsiasi utente Oracle poiché a PUBLIC è stato concesso l'accesso selezionato su dipendenze_utente:

select name
,      type
,      prior name
,      prior type
from   user_dependencies
start 
with   name='BUBS#MUNT_EENHEDEN'
and    type='PACKAGE'
connect 
by     nocycle 
       name = prior referenced_name
and    type = prior referenced_type

Campione di output

Level 1: BUBS#MUNT_EENHEDEN   PACKAGE
Level 2: BUBS_MUNT_EENHEDEN_V VIEW    BUBS#MUNT_EENHEDEN    PACKAGE
Level 3: BUBS#VERTALINGEN     PACKAGE BUBS_MUNT_EENHEDEN_V  VIEW
Level 4: ITGEN_LANGUAGES_V    VIEW    BUBS#VERTALINGEN      PACKAGE

Scenari complessi

Per scenari complessi ho ritenuto necessario utilizzare una propria vista direttamente sul dizionario dei dati. Fallo solo quando sai cosa stai facendo e quale versione di RDBMS vuoi supportare! Ad esempio, le versioni del modello di dati hanno introdotto importanti modifiche nel dizionario dei dati.

Esempio:

create or replace force view itgen_object_tree_changes_r
as

-- View: itgen_object_tree_changes_r
--
-- Overview of dependencies between a master object and all objects used by it. It can be used to analyze the reason why a project version views must be recalculated.

-- Code (alias): ote_r

-- Category: Hardcoded.
--
-- Example:
--
-- The object 'X' is invalid, since 'Y' is invalid.
