SimpleCrud works using oracle driver but not odbc

[wegoodwin]

If I use the oracle driver with simplecrud to do an insert everything works fine. If I use an ODBC connection for oracle to do an insert with simplecrud it scrambles the parameters. For example

public class testclass
        {
            [Key]
            public int keycolumn { get; set; }
            public string c1 { get; set; }
            public string c2{ get; set; }
            public string c3{ get; set; }
            public string c4{ get; set; }
        }

public static IDbConnection getDBConnection()
        {
            return new OdbcConnection("Dsn=OraDev;Uid=system;Pwd=password;");

        }

public static void OracleODBCTest()
        {

            Dapper.SimpleCRUD.SetDialect(Dapper.SimpleCRUD.Dialect.Oracle);
            testclass tc = new testclass();
            tc.c1= "a";
            tc.c2= "b";
            tc.c3= "c";
            tc.c4= "d";

            using (var connection = getDBConnection())
            {
                connection.Insert(tc);
            }


        }

When I look in the database :

c1 = "b"
c2 = "c"
c3 = "d"
c4 = "a"

It like it's moving everything over by one or something.
