Script til at finde afhængigheder på flere niveauer af en pakke

Du kan bruge en connect by på user_dependencies i de fleste tilfælde.

Bestemmelse af afhængigheder

Eksempel, der fungerer for enhver Oracle-bruger, siden PUBLIC har fået udvalgt adgang på user_dependencies:

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

Eksempeloutput

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

Komplekse scenarier

For komplekse scenarier har jeg fundet det nødvendigt at bruge en egen visning direkte på dataordbogen. Gør kun dette, når du ved, hvad du laver, og hvilken RDBMS-version du vil understøtte! For eksempel introducerede datamodelversioner store ændringer i dataordbogen.

Eksempel:

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.
