If i understand correctly, you'd like a single Table object to "dynamically" change its schema based on which engine its used with. The only way to achieve something like this is to make a copy of the table against a different schema using table.tometadata(someothermetadata, schema='someschema'). Tables do not assume to be "associated" with any one engine, so your feature request of the Table automatically setting its "schema" to the default schema of some particular engine is not possible. If you'd like to achieve this yourself, create a Table function of your own: def Table(*args, **kw): kw['schema'] = "someschema" return sqlalchemy.schema.Table(*args, **kw) --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
