我正在尝试使用 C# 从我拥有的 sql 文件中恢复空白数据库的表。

这是代码：

namespace KezberProjectManager
{
    public partial class VisitClear : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {
            string sqlConnectionString = "Data Source=JOSH-PC\\SQLEXPRESS;Initial Catalog=KezBlu;Integrated Security=True;MultipleActiveResultSets=True";
            FileInfo file = new FileInfo(Path.Combine(
    HostingEnvironment.ApplicationPhysicalPath, 
    @"App_Data\kb.sql"));

            string script = file.OpenText().ReadToEnd();

            SqlConnection conn = new SqlConnection(sqlConnectionString);

            Server server = new Server(new ServerConnection(conn));

            server.ConnectionContext.ExecuteNonQuery(script);

        }
    }
}

这是脚本：

USE [KezBlu]

我在那里放了一些东西，因为数据库可能已经设置好了，在这种情况下我想要一个新的副本。

我得到：

An exception occurred while executing a Transact-SQL statement or batch.

我在做什么有什么问题吗？我从使用 SQL Server 生成脚本获得了脚本。

我只是想让它：

 1. Clear any tables, just empty the db.

2. Create the tables and foreign keys.

谢谢

它失败是因为当您将完整脚本作为简单字符串传递给 ExecuteNonQuery 时，无法识别 GO 字。但是，接受 StringCollection 对象的 ExecuteNonQuery的重载表示接受由 GO 分隔的脚本

我会这样尝试：（未测试）

StringCollection col = new StringCollection();
col.Add(script);
server.ConnectionContext.ExecuteNonQuery(col);

如果这不起作用，那么想到的唯一解决方法是

string goSplitter = new string[] { "\r\nGO\r\n" };
string[] cmdParts = script.Split(goSplitter, StringSplitOptions.RemoveEmptyEntries);
StringCollection col = new StringCollection();
col.AddRange(cmdParts);
server.ConnectionContext.ExecuteNonQuery(col);

更新 我已经使用您提供的代码对我的数据库测试了您脚本的一小部分，这与我对使用单个字符串的 ExecuteNonQuery文档的理解相反，它按预期工作。因此，整个脚本中可能存在一些语法错误或其他问题。我建议在 Sql Management Studio 控制台中对其进行测试

更新 2
现在我真的很好奇，所以我启动了 Reflector 来调查 ExecuteNonQuery 的代码，现在这个谜团已经解决了。这些是获取单个字符串的方法的第一个反编译行。

public int ExecuteNonQuery(string sqlCommand, ExecutionTypes executionType)
{
    int num6;
    this.CheckDisconnected();
    int statementsToReverse = 0;
    int num2 = 0;
    StringCollection strings = this.GetStatements(sqlCommand, executionType, ref statementsToReverse);
    ........

因此，单个字符串被传递给一个名为 GetStatements 的内部方法，该方法返回一个 StringCollection

Phil Haack 有一篇文章描述了他创建的一个库，该库允许您运行包含GO语句的 SQL 注释。

http://haacked.com/archive/2007/11/04/a-library-for-executing-sql-scripts-with-go-separators-and.aspx

您需要使用这样的库来运行您拥有的脚本。

然而，其他人已经声明 GO 是 SSMS 的一部分；是 sql 的一部分，所以如果你用 ; 结束每条语句的最后一行 而不是 go，它应该从您的代码内部执行。

您的 SQL 中有错误。我复制并粘贴了它，运行了两次（以创建表结构），我收到错误消息，例如

无法删除对象“dbo.Employee”，因为它被 FOREIGN KEY 约束引用。

您必须以正确的顺序删除表格。从具有引用的表开始...例如先删除 [EmployeGroupFilters] 然后 Employee 等。

祝你好运。

该脚本不是纯 SQL。GO 语句不是 SQL 语言的一部分，而是编辑器预处理器的一部分，用于分隔 SQL 批处理语句。您不能使用 SqlCommand 和 ExecuteNonQuery 方法执行此类脚本。

你需要的是 sqlcmd.exe http://msdn.microsoft.com/en-us/library/ms162773.aspx
