Anda dapat menggunakan connect by on user_dependencies untuk sebagian besar kasus.
Menentukan dependensi
Contoh yang berfungsi untuk setiap pengguna Oracle sejak PUBLIC telah diberikan akses pilih pada ketergantungan_pengguna:
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
Contoh keluaran
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
Skenario kompleks
Untuk skenario kompleks, saya merasa perlu menggunakan tampilan sendiri secara langsung di kamus data. Lakukan ini hanya jika Anda tahu apa yang Anda lakukan dan versi RDBMS apa yang ingin Anda dukung! Misalnya, versi model data memperkenalkan perubahan besar dalam kamus data.
Contoh:
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.
