This error will be raised if an application created with Delphi Standard or Delphi Professional attempts to use any SQL Link driver (InterBase, Oracle, Informix, Sybase, MS-SQL). This error can also be raised if an application created with Delphi Standard attempts to use an ODBC driver. In order to create rograms that use Borland's SQL Links, you must have Delphi Client / Server and to use ODBC, you must have at least Delphi Professional.
