我尝试使用asp创建一个简单的应用程序,我遇到了问题。
程序或功能' stored_pr'期望参数' @ name',这是 没提供。
我的存储过程:
using System;
using System.Data;
using System.Configuration;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;
using System.Data.SqlClient;
public partial class _Default : System.Web.UI.Page
{
DataSet ds = new DataSet();
SqlConnection con;
//Here we declare the parameter which we have to use in our application
SqlCommand cmd = new SqlCommand();
SqlParameter @name = new SqlParameter();
protected void Page_Load(object sender, EventArgs e)
{
}
protected void Button1_Click(object sender, EventArgs e)
{
con = new SqlConnection("server=(local); database=**;uid=DefaultAppPool;pwd=*****");
cmd.Parameters.Add("@name", SqlDbType.VarChar).Value = ((TextBox)this.Page.FindControl("Pole")).Text;
cmd = new SqlCommand("spq", con);
cmd.CommandType = CommandType.StoredProcedure;
con.Open();
cmd.ExecuteNonQuery();
con.Close();
}
}
我在ASP中的代码:
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1transitional.dtd">

<form id="form1" runat="server">
<div>
<asp:TextBox ID="Pole" runat="server"></asp:TextBox>
<asp:Button ID="Button1" runat="server" Text="Submit Record" OnClick="Button1_Click" />
</div>

错误!交换这两行:
cmd.Parameters.Add("@name", SqlDbType.VarChar).Value = ((TextBox)this.Page.FindControl("Pole")).Text;
cmd = new SqlCommand("spq", con);

您的问题很可能在于这两行,尽管代码中可能还有其他问题:
cmd.Parameters.Add("@name", SqlDbType.VarChar).Value = ((TextBox)this.Page.FindControl("Pole")).Text;
cmd = new SqlCommand("spq", con);
您基本上是在命令中添加一个参数,然后通过再次添加它来有效地清除它。交换2行,你应该克服这个错误。
