Re: InstantDB: SQL query does not run


Hi Thomas,

One observation: this is a cartesian product, because there is no join
condition that links vrnt with any other table.  So it might be
generating a result set that is larger than what you intend.  If that
results in a ridiculously large result set, it could be overwhelming the
InstantDB engine.

Have you considered testing simpler queries with fewer tables until you
can build up the full 14-way join?
