SQL Table and column Parser for stored procedures

Question

Is there an application , which can parse a given set of stored procedures (SQL Server 2000) and gets all tables and associated columns that are being used in it. The stored procedure can have tables from different databases.

Output should be like TableA columnA columnC columnD

TableB columnE columnF columnG

I have written an small application using Database Edition GDR Any one interested can refer to http://tsqlparsergdr.codeplex.com

Not a concrete solution - but a line of thought.

Considered sysdepends as a potential solution - but it is notoriously unreliable at containing all the dependent object information.

but how about something Lex/Yacc derived? There are a few commercial parsers e.g.

Not looked for open-source implementation but I think I would look for that route. Here's how I started my search:

BNF syntax for ANSI SQL can be found here:

With a lex implementation of choice, this seems a relatively straight forward engineering problem from here. (albeit with some heavylifting if you want to support MS SQL extensions)
