Question

我有一个带有以下SqlDataSource的网格视图：

<asp:SqlDataSource ID="SqlDataSource1" runat="server" 
            ConnectionString="<%$ ConnectionStrings:ConnString%>" 
            SelectCommand="SELECT IDC, DESCPREVIEW, ADESCPREVIEW, DESC, ADESC, DATETOs, Active, HAVEIMG FROM CONTENT ORDER BY IDC DESC "
            UpdateCommand="[SP_UPDATE_CONTENT]" 
            UpdateCommandType="StoredProcedure">
            <UpdateParameters>
                <asp:Parameter Name="IDC" Type="Int32" />
               <asp:Parameter Name="DESCPREVIEW" Type="String" />
                <asp:Parameter Name="DESC" Type="String" />
                <asp:Parameter Name="DATETOs" Type="String" />
                <asp:Parameter Name="active" Type="Boolean" />
            </UpdateParameters>
</asp:SqlDataSource>

存储过程定义了以下参数：

alter PROCEDURE [dbo].[SP_UPDATE_CONTENT]

@IDC AS INT,
@DESCPREVIEW AS NVARCHAR(800),
@DESC  AS NVARCHAR(1500),
@DATETOs AS VARCHAR(10),
@active as bit

我在更新时遇到以下错误：

虽然这些是完全相同的参数

这里可能出现什么问题？

Answer 1

解决了问题。

显然，Update Command将SelectCommand中的所有Selected字段视为参数。

所以我将selectCommand最小化到所需的字段数。

 SelectCommand="SELECT IDC, DESCPREVIEW, DESC, DATETOs, Active FROM CONTENT ORDER BY IDC DESC "

过程或函数x指定了太多参数
