SQLA has no assumption that it would be creating tables. if you do call metadata.create_all(), which itself is optional, it actually checks for those tables already existing and will not affect them. You can "load" the definition of existing tables using Table(..., autoload=True), or create fully defined Table objects (or declarative mappings) that correspond to the existing schema. You can even leave out columns or tables you aren't concerned about. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
