I do not see a good way to pass variables to the backend's prepare statement. We had a longer discussion on this starting with the different syntax until I understood that you cannot prepare a statement like: select * from table where id=:id; until you already know the value of the variable id, i.e. the backend does not know a USING clause to specify the variables when executing the command. But then I may have missed something. It happened before. :-) Michael -- Michael Meskes Email: Michael@Fam-Meskes.De ICQ: 179140304, AIM: michaelmeskes, Jabber: meskes@jabber.org Go SF 49ers!
