Extracting object usage from SELECT

Question

I thought I had a great idea by using "explain plan" to extract the different objects (tables, views, synonyms, stored procedures etc.) that a given SELECT statement is using. However, after some fidling around I've realized that "explain plan" doesn't deal with stored procedures at all.
Is there a way I can call a parser or something on the RDBMS side to get a list of involved objects? I don't need it nested - ie. I don't need to know that a stored procedure I'm calling calls another stored procedure etc; but I do need to know what tables, views, procedures are used in the SQL.
Is there a parser available that will allow me to extract this "metadata" ? I need to pass in a "dynamic" SQL - meaning not an existing Oracle object.
Does anyone have an idea on solving this?

Answer 1

If the statement is an object in the DB, then you're right on target. But it's not. It's SELECTs from client programs, like Java etc. I'm trying to document. I have the SQLs extracted, but I would like to document the object usage/dependences on external modules.
I may have to convert the statement into a stored procedure, check the dependencies and then drop the temporary object again. I was trying to avoid DDL though.
