I often mix up the SQL expression language with the use of an ORM session, and it is great that SQLAlchemy more than supports this.
But... what are the recommended ways to keep the session in sync with what you do with the SQL expression stuff? For example, with the ORM you can't really do a batch/bulk insert (that I know of), but you *can* mix in some SQL expression language to achieve it. Here is a complete example that shows this for the standard Users/Addresses example: http://pastebin.com/BArU6hci In there I do a semi-bulk insert of addresses using both the "ORM way" and the "SQL Expression Language way". With the former way, the inserted addresses are available *with their ids* without ever seeming to have a query emitted to get them. With the latter way (SQLEL) the ORM needed to emit a query to get the addresses (even when I don't ask for id), presumably to update it's identity map. Although the latter behaviour isn't really surprising, can the query be avoided somehow? Is there a way to manually update the session/identity-map with the info? In general, is there a better way to do what I'm doing? The example is obviously a simplified one... my actual use case is batch inserting thousands of records this way and I'd like to be able to keep the ORM and avoid the extra query if I could. -- You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
