Hi,
I need to build a transaction using AR, I wrote :
        public int DeleteFunc()
        {
             TransactionScope DelTran = new TransactionScope();
            int res = 0;
            try
            {
                 //INSERT THE ROW INTO USERS
                 string DataGridInsertCommand = "INSERT INTO USERS SELECT * "
                                                + "FROM USERS "
                                                + "WHERE USERS .USERS_ID = 1" ;
                Database DataGriddb = DatabaseFactory.CreateDatabase("connection");
                DataGriddb.ExecuteNonQuery(CommandType.Text, DataGridInsertCommand);

                //DELETE THE ROW FROM USERS
                string DataGridDeleteCommand = "DELETE FROM USERS "
                                             + "WHERE USERS.USERS _ID = 1" ;

                Database DataGriddb1 = DatabaseFactory.CreateDatabase("connection");
                res = DataGriddb1.ExecuteNonQuery(CommandType.Text, DataGridDeleteCommand);

                DelTran.VoteCommit();
            }
            catch (Exception ex)
            {
                DelTran.VoteRollBack();
            }
            return res;
        }

But the rollBack doesn't works.
Whats wrong?

1) Is the TransactionScope necessary?

2) Are you distributing transactions across different system types?

3) Seems like all you need is an IDbTransaction.

Hi Bob,
What i didn't found is how to implement the :
IDbTransaction transaction = connection.BeginTransaction();

as i wrote, i use :
Database DataGriddb = DatabaseFactory.CreateDatabase("connection");
and the "connection" define (at the global.asax) like that :
try
        {
            configPath = ConfigurationManager.AppSettings["configPath"];
            source = new XmlConfigurationSource(configPath);
            ActiveRecordStarter.Initialize(typeof(USERS).Assembly, source);
        }

So, how can i implement that connection at the  
IDbTransaction transaction = connection.BeginTransaction();

Thanks
