The answer to this probably depends on exactly what your schema looks like, but based on what you've told us so far, I would probably try to create all the columns first, get them into a list or tuple, and then use "star args" to pass them into the Table constructor. Something like this: columns = [Column(name, type) for name, type in some_kind_of_iterable_generated_from_your_yaml] table = Table(theTableName, Metadata, *columns) though obviously that's a very rough example -- Kevin Horn -- You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
