Question

我有一個問題，從數據庫中獲得正確的「名稱」，結果是所有的「名稱」相同。我從相同的存儲過程中獲取信息。有沒有一種方法來指定我尋找的女巫名字？ ex。 Text='<%#Eval("tblBrand.Name") %>'獲取tblBrand中的名稱。但是這個劑量工作。

<asp:Label ID="lblProductName" runat="server" Text='<%#Eval("Name") %>' CssClass="productHead" /> 

<asp:Label ID="lblModelName" runat="server" Text='<%#Eval("Name") %>' CssClass="productHead" /> 

<asp:Label ID="lblSubCategoryName" runat="server" Text='<%#Eval("Name") %>' CssClass="productHead" /> 

<asp:Label ID="lblBrandName" runat="server" Text='<%#Eval("Name") %>' CssClass="productHead" /> 



SELECT 
    Product.ProductID, Product.Name, tblBrand.Name, SubCategory.Name, 
    tblModel.Name 
FROM   Product INNER JOIN 
         tblBrand ON Product.BrandID = tblBrand.BrandID INNER JOIN 
         tblModel ON Product.ModelID = tblModel.ModelID INNER JOIN 
         SubCategory ON Product.SubCategoryID = SubCategory.SubCategoryID 
WHERE  (Product.ProductID = @ProductID) 

Answer 1

通常我倒是別名字段查詢，然後引用別名：

<asp:Label ID="lblProductName" runat="server" Text='<%#Eval("ProductName") %>' CssClass="productHead" /> 

<asp:Label ID="lblModelName" runat="server" Text='<%#Eval("ModelName") %>' CssClass="productHead" /> 

<asp:Label ID="lblSubCategoryName" runat="server" Text='<%#Eval("SubCategoryName") %>' CssClass="productHead" /> 

<asp:Label ID="lblBrandName" runat="server" Text='<%#Eval("BrandName") %>' CssClass="productHead" /> 



SELECT  Product.ProductID, Product.Name ProductName, tblBrand.Name BrandName, SubCategory.Name SubCategoryName, tblModel.Name ModelName 
FROM Product INNER JOIN tblBrand ON Product.BrandID = tblBrand.BrandID INNER JOIN tblModel ON Product.ModelID = tblModel.ModelID INNER JOIN SubCategory ON Product.SubCategoryID = SubCategory.SubCategoryID WHERE (Product.ProductID = @ProductID)

將列別名，使數據契約明確無誤。

SELECT 
    Product.ProductID, 
    Product.Name AS ProductName, 
    tblBrand.Name AS BrandName, 
    SubCategory.Name AS SubCategoryName, 
    tblModel.Name AS ModelName 
....
