我的代码如下:
               string sql1 = "SELECT CustomerName,SumMark,ChargeMoney FROM TblUserGas left join tblClient on TblUserGas.customerId=tblClient.Customerid where complete=0  " + sqlhou + " ORDER BY ChargeDate DESC";
                DataSet ds = new DataSet();
                SqlDataAdapter mycommand = new SqlDataAdapter(sql1, SqlConn);
                mycommand.Fill(ds, "TblUserGas");
                mycommand.Fill(ds, "tblClient");
      
                jjtrq.Report.Gasqian yongqituReport = new jjtrq.Report.Gasqian();
                yongqituReport.SetDataSource(ds.Tables["TblUserGas"].DefaultView);
                yongqituReport.SetDataSource(ds.Tables["tblClient"].DefaultView);
                crystalReportViewer1.ReportSource = yongqituReport;
                SqlConn.Close();显示结果如下:
CustomerName这个字段就是显示不出来,怎么回事呢?
