我希望用户输入显示的所有数据(数据库中的列),填写并提交。我无法使用HTML.HiddenFor
元素自动生成Id和CompanyID。
System.Data.SqlClient.SqlException:列名或提供的值数与表定义不匹配..
型号:
namespace Project.Models
{
public class Contact
{
public int Id { get; set; }
public string FirstName { get; set; }
public string LastName { get; set; }
public string Email { get; set; }
public int Phone { get; set; }
public int CompanyID { get; set; }
}
}
查看:
@model Project.Contact
<h2>Create Contact</h2>
@using (Html.BeginForm("Create", "Home", FormMethod.Post))
{
<table>
<tr>
<th>First name</th>
<th>Last name</th>
<th>Email</th>
<th>Phone</th>
</tr>
<tr>
<td>@Html.HiddenFor(m => m.Id)</td>
<td></td>
<td>@Html.TextBoxFor(m => m.FirstName)</td>
<td>@Html.TextBoxFor(m => m.LastName)</td>
<td>@Html.TextBoxFor(m => m.Email)</td>
<td>@Html.TextBoxFor(m => m.Phone)</td>
<td>@Html.HiddenFor(m => m.CompanyID)</td>
</tr>
</table>
<br />
<input type="submit" name="btn" class="btn-primary" value="Create" />
}
控制器:
using Arbetsprov_Sublime___Andre_Kordasti.Models;
using System.Collections.Generic;
using System.Data.SqlClient;
using System.Web.Mvc;
namespace Arbetsprov_Sublime___Andre_Kordasti.Controllers
{
public class HomeController : Controller
{
public ActionResult Index()
{
return View();
}
[HttpGet]
public ActionResult Create()
{
return View();
}
[HttpPost]
public ActionResult Create(Contact model)
{
var connection = new SqlConnection(@"Data Source=.\SQLExpress;Initial Catalog=Sublime;Integrated Security=True");
connection.Open();
var command = new SqlCommand("INSERT INTO Contact Values('" + model.Id + "','" + model.FirstName + " " + model.LastName + "','" + model.Email + " " + model.Phone + "','" + model.CompanyID + "')", connection);
command.ExecuteNonQuery();
return View();
}
}
}
答案 0 :(得分:1)
var command = new SqlCommand("INSERT INTO Contact(Id,FirstName,LastName,Email,Phone,CompanyId) Values('" + model.Id + "','" + model.FirstName + " " + model.LastName + "','" + model.Email + " " + model.Phone + "','" + model.CompanyID + "')", connection);
command.ExecuteNonQuery();
如果有一个必须是autoGenerated的列,你必须告诉你给出哪些列的值,以便sql知道未提及的属性应该是autoGenerated

也许您的联系表“ID”列值转发器。例如:当前身份证已经有
var command = new SqlCommand("INSERT INTO Contact (Id, FirstName, LastName, Email , Phone, CompanyID) Values('" + model.Id + "','" + model.FirstName + " " + model.LastName + "','" + model.Email + " " + model.Phone + "','" + model.CompanyID + "')", connection);
command.ExecuteNonQuery();
或(如果你的表id列是自动递增的话)
var command = new SqlCommand("INSERT INTO Contact (FirstName, LastName, Email , Phone, CompanyID) Values('" + model.FirstName + " " + model.LastName + "','" + model.Email + " " + model.Phone + "','" + model.CompanyID + "')", connection);
command.ExecuteNonQuery();
答案 2 :(得分:0)
尝试不向其发送ID
var command = new SqlCommand("INSERT INTO Contact(FirstName,LastName,Email,Phone,CompanyId) Values("'"+ model.FirstName + "',' " + model.LastName + "','" + model.Email + "',' " + model.Phone + "','" + model.CompanyID + "')", connection);
command.ExecuteNonQuery();
如果它没有工作,请告诉我抛出的异常是相同的还是改变的。
您正在使用的查询中发送给我的评论中有一些comass缺失&#39;,&#39;。
当你说
时INSERT INTO tbl(Column1,Column2,Column3) values ('value1''value2'+','value3')
它会给你同样的错误,因为你提到了3列,但只提供了2个值。希望我清楚。
