Question

我使用SQL Server SMO将.bak还原到新数据库，但无法正常工作。

sql server是2012，smo对象版本来自最新的sdk版本11.0

文件.bak是使用sql management studio 2012，相同的本地电脑，在同一个编码电脑上创建的。

我得到的错误信息是：

服务器'SERVER'的恢复失败。

我的代码出了什么问题？

string dbPath = Path.Combine(@"d:\my data", dbName + "_db" + ".mdf");
string logPath = Path.Combine(@"d:\my data", dbName + "_db" + "_Log.ldf");

Restore restore = new Restore();

BackupDeviceItem deviceItem = new BackupDeviceItem("d:\template.BAK", DeviceType.File);
restore.Devices.Add(deviceItem);
restore.Database = dbName + "_db";

RelocateFile relocateDataFile = new RelocateFile("Data", dbPath);
RelocateFile relocateLogFile = new RelocateFile("Log", logPath);

restore.RelocateFiles.Add(relocateDataFile);
restore.RelocateFiles.Add(relocateLogFile);

restore.Action = RestoreActionType.Database;
restore.ReplaceDatabase = true;
restore.SqlRestore(server);

更新：我放弃了SMO解决方案，并尝试了

 using (SqlConnection connection = new SqlConnection("Data Source=server;user id=sa;password=xxxxx;"))
        {

            using (SqlCommand command = new SqlCommand(@"RESTORE DATABASE beauty01 FROM DISK = 'd:\template.bak' WITH RECOVERY, MOVE 'beauty1' TO 'D:\MyData\beauty01_Data.mdf', MOVE 'beauty1_log' TO 'd:\Mydata\beauty01_Log.ldf', REPLACE", connection))
            {
                connection.Open();
                // Add the parameters for the SelectCommand.


                command.CommandType = CommandType.Text;
                command.ExecuteNonQuery();
            }

        }  >> work good.

谢谢大家。

我成功使用SMO来恢复数据库。我会分享我的代码。希望能帮助到你。这个解决方案有一点需要注意，它认为你只有一个主数据文件。获取匹配日志和数据文件非常棘手，并且可能在很多方面出错。无论如何，试着让我知道这有帮助。
