The path to that, since I wanted this to work for Postgres GIS functions as well, is a new method is added to TypeEngine called something like "bind_converter()", MSBinary provides func.convert() from its bind_converter() method, and compiler.visit_bindparam() calls upon this method. A little bit of plumbing would need to exist such that MSBinary can determine exactly how the func.convert() arguments are passed. This is something that can be worked out as a patch to be reviewed, we should add a trac ticket for it. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
