從ASP頁運行插入查詢時出現“過程或函數指定了太多參數”錯誤

Question

我試圖使用ASP detailsview將變量傳遞給MSSQL存儲過程，然后將值插入到多個表中。 當我在SQL Management Studio中運行它時，存儲過程非常有效。 我將所有存儲過程的變量設置為參數，但是當我的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。

錯誤信息：

Answer 1

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

這是一個綁定字段，它將作為參數添加到存儲過程中，並且不屬於參數列表。 如果可能，嘗試將其轉換為TemplateField並使用Eval代替Bind 。

Answer 2

我想我在黑暗中拍攝，但這個領域是否會引發問題？

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

DataSource已count為參數，存儲過程也是如此。 countYtD字段不存在，所以我認為會自動添加，因為它是一個Bound Field。

Answer 3

是的，我在為gridview調用數據源的更新方法時遇到了同樣的錯誤。

數據源稱為存儲過程，用於對數據庫執行更新。

我用這種方式糾正了這個問題：

首先，確保在數據源中聲明所有SP參數，在SP中包含DataKeys。

其次，使用<%# Bind("some Field") %>要編輯的所有字段。 請勿綁定SELECT命令中的任何其他字段。 請改用EVAL() 。

第三， UPDATE參數的名稱必須匹配任何BIND()值的名稱。 AND ALL更新參數必須綁定到輸入控件（文本框等）。

調用Data Source Update()方法時，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，我有一個專欄。 它具有<ItemTemplate>和<EditItemTemplate>定義。 在<ItemTemplate> ，我Eval() SELECTED列Name，

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

在<EditTemplate> ，我聲明了一個<asp:textbox>控件，以從SELECT命令接收“FirstName”值的值。

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

在數據源UPDATE參數中，我定義了這個參數

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

現在，當頁面回發時，將解析頁面，並且將從控件中提供所有UPDATE參數的值，這些控件的值為BIND() ，其名稱與UPDATE參數相同。

參數名稱拼寫中的任何不匹配，或任何EXTRA BIND()的UPDATE參數中未包含的值都將引發“Too Many Parameters”錯誤。
