SA 0.7 generates events both at the ORM level and at the SQL level. See: http://www.sqlalchemy.org/docs/07/core/event.html http://www.sqlalchemy.org/docs/07/core/events.html For example, there is a 'before_execute' event which you could listen for, and look for INSERT clauses. If you can't upgrade to 0.7, you might be able to use a ConnectionProxy: http://www.sqlalchemy.org/docs/07/core/interfaces.html Hope that helps, Simon -- You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
