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。
