I do not think parsing the from clause would be all that easy since you have to allow for encountering terms like inner join, right outer join, etc... then what about dynamic SQL where portions of the SQL statement are going to be held in variables? You may also have to deal with commented out sections of source.
I would be interested in getting a copy of a routine that can automatically extract SQL from stored code even if it had no ability to deal with dynamic SQL (since no well written system should use more than a few dynamic SQL statements).
