Update Oracle from Datagridview

Question

Hi,

As my Subject title mentioned I'm trying to update an Oracle DB from the datagridview table.This is where I'm currently at now...

              //Establish Oracle DB connection.  

              int connectionCounter = 0;  

                bool boolUpdateData = true;  

                while (boolUpdateData && connectionCounter < 3)  

                {  

                    try  

                    {  

                        localConnection = new OracleConnection(localFunction.localConnectionString);  

                        localConnection.Open();  

                        boolUpdateData = false;  

                    }  

                    catch (Exception localException)  

                    {  

                        localFunction.WriteEventLog(localException.ToString(), "OPCAlarmConfig");  

                    }  

                    connectionCounter++;  

                }  

                //???

                OleDbDataAdapter da = new OleDbDataAdapter();  

                oleda.SelectCommand = cmd;  

                OleDbCommandBuilder cb = new OleDbCommandBuilder(da);  

                oleda.Fill(ds);  

                excelGridView.DataSource = ds.Tables[0];  

                oleda.Update(ds); 

I'm not very sure how am I supposed point to the Oracle table I want to update.

Thanks in advance for any help or advice offered.
