Sorry about terse nature of the website information. I need to repent and write better documentation. ADO is a strictly Microsoft animal. It seems that Microsoft invented ODBC, which was quickly recognized as such a great idea that everyone adopted it. So they had to invent something "better", and that was supposed to be ADO. As it happens, the most redeeming feature of ADO is that in runs in ODBC mode by default. That having been said, it is very powerful, and does have the ability to reach out to almost any form of tabular data. But it does so using COM calls, which are very proprietary. I have been worrying over the problem of how to read an ADO dataset from Linux for years. I was hoping that IronPython and Mono would provide the answer, but it turns out that ADO.NET also uses COM, and looses some of the power (like timely update of .rowcount) in the process. It does not even work well in a pure Windows environment. I have abandoned that code fork. The open source odbc products leave things to be desired, too, the largest being that they only work in ODBC mode and cannot switch to ADO mode when the connection string requires it. I have begun to think that eGenix is on to something with their "mxODBC connect" product: they use a connection server. Here's how it might be done: Somewhere, there would have to be a Windows box running an ADO connection server program. Perhaps it could be on the actual database server, perhaps not. A copy of adodbapi which notices that it is running where os.name != 'nt' would bring up a link to the connection server (using RPC?) which would do the actual data access and pass the results back. A simple server would be trivial to write. One which worked well under a heavy thread load might not be so easy, but my thinking is that a heavily used django server which made frequent use of an MSSQL database would already be running on a Windows box itself and would not need any connection server. If there is interest, I will start coding a prototype. -- You received this message because you are subscribed to the Google Groups "Django developers" group.
