Psqlodbc driver couldn't use the library unless the library could handle multiple protocol. What the driver has suffered from is to get the fields' info of a query result or the parameters' info of a statement. The info is needed even before the execution of the statement(i.e it's only prepared). regards, Hiroshi Inoue http://www.geocities.jp/inocchichichi/psqlodbc/
