How to reuse Cursor Number? - C# / Gupta sqlbase 9

How to reuse Cursor Number? - C# / Gupta sqlbase 9

How to reuse Cursor Number? - C# / Gupta sqlbase 9

I know I could handle this with a large sql command or SQL procedure, but I want to make a more robust process that can accurately report progress and support cancellation.

Unless I close the 2nd sqlbase connection after each row read from the first connection, it will assign a new cursor for the query within while(reader.read()) loop.
I've handled this in the code below, but disconnecting doesn't seem the right way to handle this.

Any tips?


     private void dostuff()
            bool bError = false;
            string sErrorMessages = "";
            int iCount = 0;
            int iTotal = 18000; //test value
            string sID = "";
            string sDts = "";
            string sGetID = "select id, DTS from tableA";
            string sGetMinDTS = "select min(DTS) from TableB where id = ";
            OleDbConnection conn1 = new OleDbConnection("Provider=SQLBaseOLEDB;Data Source=DBNAME;User ID=admin;Password=myPass;");
            OleDbConnection conn2 = new OleDbConnection("Provider=SQLBaseOLEDB;Data Source=DBNAME;User ID=admin;Password=myPass;");

                OleDbCommand commit = new OleDbCommand("commit", conn2);
                OleDbCommand comGetID = new OleDbCommand(sGetID, conn1);

                OleDbDataReader reader = comGetID.ExecuteReader();

                while (reader.Read())

                    progressBar1.Value = Convert.ToInt32(iCount * (100.0 / iTotal));

                    sID = reader[0].ToString();
                    sDts = reader[1].ToString();

                    OleDbCommand comGetMinID = new OleDbCommand(sGetMinDTS + sID, conn2);
                    OleDbDataReader reader2 = comGetMinID.ExecuteReader();
                    while (reader2.Read())
                        if (reader2[0].ToString().Length > 0)
                            if (Convert.ToDateTime(reader2[0].ToString()) < Convert.ToDateTime(sDts))
                                OleDbCommand upd = new OleDbCommand("update tableB set dts = " + reader2[0] + "where id = '" + sID + "'", conn2);

            catch (OleDbException e)

                sErrorMessages = "";
                for (int i = 0; i < e.Errors.Count; i++)
                    sErrorMessages +=
                                     "ErrCount# " + (i + 1) + "\n" +
                                     "Message: " + e.Errors[i].Message + "\n" +
                                     "NativeError: " + e.Errors[i].NativeError + "\n" +
                                     "Source: " + e.Errors[i].Source + "\n" +
                                     "SQLState: " + e.Errors[i].SQLState + "\n\n" + sGetID
                    bError = true;
