Parsing SQL takes real dedication. Especially if you want to be able
to go beyond just MySQL.
Are there any free libraries out there that are able to translate SQL
text (especially the DDL bit, where vendors go out of their way to be
non-standard) into a suitable abstract form for further processing?
Hmm, actually, now thinking of it, the MySQL dump format is along the
lines of Joe's example. Maybe it's possible to access the parsing of
that somehow and use it in a port program? I'm not familiar with the
code of MySQL, so this might be futile, but you never know.
