Use U2 ODBC as 2.0 – Select this option to run U2 ODBC version 2.0. By default, ODBC runs in version 3.0. Sometimes, the SQL syntax generated by Crystal Reports or Microsoft SQL Server 2008 is not recognized by the UniVerse SQL engine. In those instances, users running Crystal Reports or Microsoft SQL Server 2008 will need to use U2 ODBC 2.0.
