从ASP页运行插入查询时出现"过程或函数指定了太多参数"错误

Question

我试图使用ASP detailsview将变量传递给MSSQL存储过程,然后将值插入到多个表中.当我在SQL Management Studio中运行它时,存储过程非常有效.我将所有存储过程的变量设置为参数,但是当我的ASP页面运行时,我仍然收到错误(下面).我的ASP代码和存储过程也包含在错误消息下面.

任何帮助将不胜感激.这个问题开始变得非常令人沮丧.

错误信息:

Answer 1

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

这是一个绑定字段,它将作为参数添加到存储过程中,并且不属于参数列表.试试,如果可能的话,将其转化为一个TemplateField和使用Eval代替Bind.

Answer 2

我想我在黑暗中拍摄,但这个领域是否会引发问题？

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

DataSource具有count参数,存储过程也是如此.该countYtD字段不存在,所以我认为会自动添加,因为它是一个绑定字段.
