Question

以下示例1，2我写了以下内容：

using System;
using System.Data.SqlClient;
using System.IO;
using Microsoft.SqlServer.Management.Smo;
using Microsoft.SqlServer.Management.Common;

namespace ScriptRunner
{
    class Program
    {
        static void Main(string[] args)
        {
            var script = File.ReadAllText("Test.sql");
            const string sqlConnectionString = @"Data Source=my\ds;
                    Initial Catalog=myic;
                    Connection Timeout=0;
                    Integrated Security=true";
            SqlConnection connection = null;
            Server server = null;
            try
            {
                connection = new SqlConnection(sqlConnectionString);
                server = new Server(new ServerConnection(connection));
                connection.Open();
                server.ConnectionContext.BeginTransaction();
                server.ConnectionContext.ExecuteNonQuery(script);
                server.ConnectionContext.CommitTransaction();
            }
            catch { server.ConnectionContext.RollBackTransaction(); }
            finally { connection?.Dispose(); }
        }
    }
}

除交易外，一切正常。该命令刚刚运行，如果有错误，之前的所有内容都已经在数据库中。如何使交易在这里工作？

[编辑] 当我更改代码以在SqlConnection级别打开事务时（here建议它，应该没有区别）：

    SqlTransaction transaction = null;
    try
    {
        connection = new SqlConnection(sqlConnectionString);
        server = new Server(new ServerConnection(connection));
        connection.Open();
        transaction = connection.BeginTransaction();
        server.ConnectionContext.ExecuteNonQuery(script);
        transaction.Commit();
    }

抛出InvalidOPexception：“当分配给命令的连接处于挂起的本地事务中时，ExecuteNonQuery要求命令具有事务。该命令的Transaction属性尚未初始化。” < / p>

但我没有看到可以访问命令对象的地方。

我遇到了同样的问题“ExecuteNonQuery需要命令进行交易......” 似乎如果为ServerConnection执行begin / commit事务，而不是为SqlConnection执行，那么一切正常。

...
SqlConnection connection = new SqlConnection(sqlConnectionString);
ServerConnection srvCon = new ServerConnection(connection);

try
{
     server = new Server(srvCon);

     srvCon.BeginTransaction();
     server.ConnectionContext.ExecuteNonQuery(script);
     srvCon.CommitTransaction();
}
catch
{
     srvCon.RollBackTransaction();
}
...
