我正在尝试学习如何使用CSHTML和.NET来做一个简单的数据库连接和查询输出到网站,但我有几个小时的问题,从我的连接字符串到实际查询我遇到了麻烦。请帮助我找到问题并使这个基本查询正常工作。
数据库= Microsft SQL Express
schema = id(int),user(nchar(10)),password(char(32))。
Web.Config的内容
<?xml version="1.0" encoding="utf-8"?>
<configuration>
<connectionStrings>
<add name="MyConnectionString"
connectionString="Data Source=LAPTOP\SQLEXPRESS;Initial Catalog=databasename;Integrated Security=False;User ID=sa;Password=password" />
</connectionStrings>
<system.web>
<compilation debug="true" targetFramework="4.0" />
</system.web>
</configuration>
以下是我在查询中失败的尝试。我试图使用w3学校http://www.w3schools.com/aspnet/webpages_database.asp中的例子无济于事。
ListProducts.cshtml的内容
@{
var connectionString = "Data Source=LAPTOP\\SQLEXPRESS;Initial Catalog=databasename; Integrated Security=True";
var providerName = "System.Data.SqlClient";
var db = Database.OpenConnectionString(connectionString, providerName);
var selectQueryString = "SELECT * from user";
}
<html>
<body>
<h1>Test</h1>
<table>
<tr>
<th>id</th>
<th>username</th>
<th>password</th>
</tr>
@foreach(var row in db.Query(selectQueryString))
{
<tr>
<td>@row.id</td>
<td>@row.user</td>
<td>@row.password</td>
</tr>
}
</table>
</body>
</html>
每次我跑步时都会收到此错误
Server Error in '/' Application.

猜测问题与数据库(初始目录)有关。
Data Source=LAPTOP\\SQLEXPRESS;Initial Catalog=databasename
您的数据库是否真的命名为“databasename”?

原来它一定与我的数据库有关。我有一个名为user的表,其中一列也称为user。我将表用户重命名为用户,更新了代码,现在一切正常!
