Jamie, after thinking about this, I don't think we should worry about the specifics of the characters that we use, as long as we can agree on what gets entered into a PD message box, the specific instance of the external ('sqlite', 'psql', etc.) can handle the conversion to what the specific database uses.

From what I have seen on this thread, is it right that the '?' syntax does NOT have an identifier following it? I think it would be very helpful if we use identifiers in the SQL if only to make the binding to the proper datatypes easier, as per my last email.
