Question

Is it possible to write a PL/SQL query to identify a complete list of a stored procedures dependencies? I’m only interested in identifying other stored procedures and I’d prefer not to limit the depth of nesting that it gets too either. For example, if A calls B, which calls C, which calls D, I’d want B, C and D reported as dependencies for A.

On this page, you will find the following query which uses the PUBLIC_DEPENDENCY dictionary table:

 SELECT lvl      , u.object_id      , u.object_type      , LPAD (' ', lvl) || object_name obj    FROM ( SELECT LEVEL lvl, object_id             FROM SYS.public_dependency s          START WITH s.object_id =                       ( SELECT object_id                           FROM user_objects                          WHERE object_name = UPPER ('&OBJECT_NAME')                            AND object_type = UPPER ('&OBJECT_TYPE'))          CONNECT BY s.object_id = PRIOR referenced_object_id          GROUP BY LEVEL, object_id) tree       , user_objects u   WHERE tree.object_id = u.object_id ORDER BY lvl /
