An application, orginally developed in C++ under VS 6.0 which inserts integers,varchar and binary large objects in a database (with SQLPrepare(), SQLBindParameter() and SQLExecute()). Originally the database was an Oracle 8.x and the application runs under Windows 2000 (via ODBC). Then we have tried a Postgres 8.x (on a server) and after changing the syntax of some statements, it worked. Now I have Windows XP Professional V.2002, SP 2 and .NET 1.1 and I get the error message: 'ERROR: type "lo" does not exist'. I´ve tried various Versions of the ProsgreSQL OBDC driver. All with the same result.
