you'd have very limited usage options here, and certainly the ORM would be out
of the question. You could pretty much only use engine/connection.execute()
with a straight string.
you should inform the partner you're working with that it's a major security
hazard for the database to not accept bound parameter sets. Without them,
all applications are wide open for SQL injection attacks:
