  {
    dLib = new DataLibrary("VillageMate", true);

    dtInsertData = dLib.GetDataTable("SELECT * FROM VillageMate_ESS  where LogID=(select  max(LogID) from [VillageMate_ESS])");//Select the last inserted row from table
    if (dtInsertData.Rows.Count > 0)
    {

       dLib = new DataLibrary("ESS", true);

       sqlQUERY = "INSERT INTO  [MSTR_Employee] (FirstName, NationalID, EmployeeCode,CreatedDateTime,RecordStatus) VALUES ('" + dtInsertData.Rows[0]["Name"].ToString() + " ' , '" + dtInsertData.Rows[0]["IDNumber"].ToString() + "' , '" + dtInsertData.Rows[0]["RFID"].ToString() + "' , '" + DateTime.Now.ToString() + "' , '" + true + "')";

       sqlQUERY += "INSERT INTO  [MSTR_Employee_Optional] (TNAEnrollID, CreatedDateTime,RecordStatus) VALUES ('" + dtInsertData.Rows[0]["RFID"].ToString() + "' , '" + DateTime.Now.ToString() + "' , '" + true + "')";

       int status = dLib.ExecuteNonQuery(sqlQUERY);

     catch (Exception ee)
      {
        WriteLogs.WriteErrorLogs(-1, 0, GetType().FullName + "." + MethodBase.GetCurrentMethod().Name, ee.ToString());

        dtInsertData = null;
      }
