Could you zip up the database and send it to me (only if it zips to under
400K though). I'll try out the query and see if I can figure out what's
going on. Email is peter.hearty@lutris.com.

Subject: Re: InstantDB: SQL query does not run

shows

though a

complete

>table. No, I can't go on in the application with another query after the
bad

painted

simple

them
>are the same, the query works. If data are stored without redundancy, often

(really hope

server.
