Question

我对gridview进行了过滤，该过滤基于project_id，date和vehicle_no

但我的查询未正确过滤。

问题是： -

如果我过滤今天的日期并检查，则记录不会显示和数据，这是完全正确的。
但如果过滤exact date，project_id和vehicle_no，则应显示一条记录。但它仍然没有显示任何记录。

以下是我对过滤的查询。

strquerry = "SELECT DISTINCT sv.mkey, vehicle_no, TO_CHAR (date_in, 'dd/MM/yyyy') || ' & ' || time_in vehicleindate_time, TO_CHAR (date_out, 'dd/MM/yyyy') || ' & ' " +
             "|| time_out vehicleoutdate_time, gate_no_in || ' & ' || gate_no_out ingate_outgateno, gd.good_type goods_type, net_weight netweight, TO_CHAR (challan_date, 'dd/MM/yyyy') " +
             "|| ' & ' || challan_no challandate_no,remark_in remarkin, NULL receipt_no, date_in FROM xxcus.xxgid_supinv sv, xxcus.xx_supinv_goodtype gd, " +
             "xxcus.xxacl_xxgid_user_mst ms WHERE (gd.good_type_code(+) = sv.good_type) AND " +
             "( sv.project_id = '" + cmbProjectName.SelectedValue + "' AND TO_CHAR (date_in, 'dd/MM/yyyy') = '" + txtExpCal.Value + "' OR vehicle_no = '" + ddlVehicleno.SelectedValue + "' ) ORDER BY date_in DESC, vehicle_no";

更新

调试后的真实查询

SELECT DISTINCT sv.mkey, vehicle_no,
               TO_CHAR (date_in, 'dd/MM/yyyy')
            || ' & '
            || time_in vehicleindate_time,
               TO_CHAR (date_out, 'dd/MM/yyyy')
            || ' & '
            || time_out vehicleoutdate_time,
            gate_no_in || ' & ' || gate_no_out ingate_outgateno,
            gd.good_type goods_type, net_weight netweight,
               TO_CHAR (challan_date, 'dd/MM/yyyy')
            || ' & '
            || challan_no challandate_no,
            remark_in remarkin, NULL receipt_no, date_in
       FROM xxcus.xxgid_supinv sv,
            xxcus.xx_supinv_goodtype gd,
            xxcus.xxacl_xxgid_user_mst ms
      WHERE (gd.good_type_code(+) = sv.good_type)
        AND (       sv.project_id = '1368'
                AND TO_CHAR (date_in, 'dd/MM/yyyy') = '19-09-2015'
             OR vehicle_no = '29'
            )
   ORDER BY date_in DESC, vehicle_no

Answer 1

问题是TO_CHAR (date_in, 'dd/MM/yyyy') = '19-09-2015'

您使用/分隔符转换日期，但参数中的日期具有-分隔符。

将其更改为TO_CHAR (date_in, 'dd-MM-yyyy')
