John is correct. Parsing SQL is not much of a trick, especially if I can
do it in a bourne shell script. You need a database engine to carry out
the requests.

I have not discussed this with the author yet, but mbase(metalbase) is a
PD database ported to many platforms which would do the trick quite

All someone would have to do is to tokenize and parse the SQL code (shql
may help as an example), and call mbase routines to do the manipulation.

I am surprised no one has done this before. We have lots of PD editors,
and a few good spread sheets, but few if any PD databases.
