用于存储过程的 SqlDataSource 的 QueryStringParameter

Question

我有一个SqlDataSource 并想根据查询字符串对其进行过滤。但是使用SelectParameters / QueryStringParameter，它似乎没有将值传递给存储过程。

数据源配置如下：

<asp:SqlDataSource runat="server" ID="sqlGetDetails"
     ConnectionString='<%$ ConnectionStrings:SqlDbConnectionString.ConnectionString %>'
     SelectCommand= "GetDetails" SelectCommandType="StoredProcedure">
     <asp:SelectParameters>
         <asp:QueryStringParameter Name="AppID" QueryStringField="AppID" DbType="String" Direction="Input" DefaultValue="" ConvertEmptyStringToNull="true"/>
     </asp:SelectParameters>
</asp:SqlDataSource>

失败并出现错误：

过程或函数“GetDetails”需要参数“@AppID”，但未提供该参数

存储过程是用这样的代码创建的：

CREATE PROCEDURE [dbo].[GetDetails]
    @AppID NCHAR(40)
AS
BEGIN
    SELECT * 
    FROM dbo.Details 
    WHERE dbo.Details.AppID = @AppID
END
GO

堆栈跟踪：

Answer 1

您的 SelectCommand 必须如下所示：

From:

SelectCommand= "GetDetails"

To:

SelectCommand= "GetDetails 12"

12 作为参数。

如果你能通过类似的东西，我从来没有尝试过

SelectCommand= "GetDetails AppID//Serve as the value".. Just think about it.
