Well even without parse-into-a-named-statement they could be using PQexecParam for now. I'm talking with them trying to straighten this out. Is there anything technically hard in adding this functionality to libpq? It looks like it's just mechanically adding more entry points to existing code. Were you leaving this as a honey pot hoping it would attract new programmers? I'm looking at doing it now. The describe statement part could be much trickier but DBD::Pg doesn't really need that for basic functionality. It would be a useful feature for later though. I do wonder whether DBD::Pg is really best off using libpq. From what I'm reading now it seems the "read every record before returning" behaviour is rooted in the libpq interface. Ideally a program should be able to stream results and process them as they arrive. It looks like PQgetResult might be relevant but the documentation isn't clear whether each result returned is for an entire query in the original statement or if they can be partial result sets. -- greg ---------------------------(end of broadcast)--------------------------- TIP 4: Don't 'kill -9' the postmaster
