「過程或函數具有太多的參數指定」錯誤時，從ASP頁運行插入查詢

Question

我想要使用ASP detailsview將變量傳遞給MSSQL存儲過程，然後將值插入到多個表。當我在SQL Management Studio中運行存儲過程時，存儲過程可以正常工作。我將所有存儲過程的變量設置爲參數，但當我的ASP頁面運行時，我仍然收到錯誤（下面）。我的ASP代碼和存儲過程也包含在錯誤消息的下面。

任何幫助將不勝感激。這個問題開始變得非常令人沮喪。

錯誤消息：

Answer 1

我想我是在黑暗中拍攝的，但是這個領域是否會造成問題？

<asp:BoundField DataField="countYtD" HeaderText="Count" 
     SortExpression="countYtD" /> 

數據源有count作爲參數，存儲過程也是這樣。 countYtD字段不存在，所以我認爲這將被自動添加，因爲它是一個綁定字段。

Answer 2

<asp:BoundField DataField="countYtD" HeaderText="Count" 
       SortExpression="countYtD" /> 

這被綁定的字段，它會被添加作爲參數傳遞給存儲過程，不屬於參數列表。如果可能，請嘗試將其轉換爲TemplateField，並使用Eval代替Bind。

Answer 3

是的，我在調用GridView的數據源更新方法時遇到同樣的錯誤。

數據源調用存儲過程來執行數據庫更新。

我糾正這個問題是這樣的：

首先，確保你聲明所有的SP參數中的數據源，包括在SP的DataKeys。

其次，要編輯的所有字段都使用<%# Bind("some Field") %>進行綁定。 不要綁定來自SELECT命令的任何其他字段。改爲使用EVAL()。

三，名稱UPDATE參數必須匹配任何BIND()值的名稱。 AND所有更新參數必須綁定到輸入控件（文本框等）。

當數據源Update()方法被調用時，它將解析回發數據並查找所有BIND()值。這些值必須與更新參數定義中定義的NAMES匹配。

例如，我有一個Column。它有一個<ItemTemplate>和<EditItemTemplate>的定義。在<ItemTemplate>，我​​所選列名稱，

<ItemTemplate> <%# Eval("LastName") %> </ItemTemplate> 

在<EditTemplate>，我宣佈一個<asp:textbox>控制接收來自SELECT命令中的「名字」值的值。

<EditItemTemplate> 
    <asp:TextBox ID="tbFirstName" runat="server" text='<%# Bind("FirstName") %>'></asp:textbox> 
</EditItemTemplate> 

在數據源更新PARAMATERS，我定義這個參數現在

<UpdateParameters> 
    <asp:parameter Name="FirstName" DbType="String" DefaultValue="" /> 
</UpdateParameters> 

，當頁面回，頁面會被解析併爲所有UPDATE PARAMATERS的值將提供來自其值爲BIND()且具有相同名稱UPDATE參數的控件。

任何參數名稱拼寫不匹配或任何額外的BIND()對於不包含在UPDATE參數中的值都會引發「太多參數」錯誤。
