So, does doing this actually create a new table in the DB? I tried this, and in my instance it failed, but I could see it trying to run a "create table" command. Is this the way it works? Is there no other way? The user I connect with will not have privileges to do this. >If you need to reflect an actual table in the DB, and you'd like to override >what columns are considered as part of the primary key within your >application, you specify >those columns explicitly as in >http://www.sqlalchemy.org/docs/05/metadata.html#overriding-reflected-columns. >> I can reflect a table as long as I connect as the table owner which as >> I stated before I will not be able to do.

FYI, using megrok.rdb you must include the class property __table_args__ as a dictionary i.e. Class ReflectedTable(megrok.rdb.Model): megrok.rdb.reflected() __table_args__ = {'schema':'someowner'}
