Notes on DEPTREE

January 5, 2012

After writing my own scripts to find either all parents or children of an object, I took a look at Oracle’s solution to find dependencies:

$ORACLE_HOME/rdbms/admin/utldtree.sql

It was actually written about 20 years ago, in 1991:
Rem rkooi 10/19/91 – Creation

Running the script, creates a number of objects:

OBJECT_AND_OBJECT_ID
----------------------------------------------------------------------------------------------------
PROCEDURE   SYS.DEPTREE_FILL    3304377
SEQUENCE   SYS.DEPTREE_SEQ    3304375
TABLE   SYS.DEPTREE_TEMPTAB    3304376
VIEW   SYS.DEPTREE    3304378
VIEW   SYS.IDEPTREE    3304379

7 rows selected.
