I think what Tom is saying is that you'll be able to set prepareThreshold to 1 in the driver (always use named server-side prepared statements) and the server will automagically do the right thing. Right now, the big problem is that only unnamed prepared statements include the "feature" of being able to consider parameters in the query plan (since unnamed statements are not reused, there's no sense in planning them before you have parameters). Other aspects of using prepared statements through the jdbc driver wouldn't change, but we should be able to forget about prepareThreshold (if I understand this correctly), which would be very nice. --- Maciek Sakrejda | System Architect | Truviso 1065 E.
