我使用SQL Server SMO一个.bak的恢复到一个新的数据库,但未能奏效。
SQL服务器2012和SMO对象版本是最新的SDK版本11.0
.bak的文件是使用SQL管理工作室2012年,同样的本地PC,在相同的编码PC以及创建。
该错误消息我得到的是:
还原失败的服务器“服务器”。
这有什么错我的代码?
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surrended SMO解决方案,并试图
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.
感谢所有。
我成功地使用SMO
来恢复数据库。 我会分享我的代码。 希望能帮助到你。 该解决方案有一点需要注意的是,它认为你只有一个主数据文件。 获取匹配了日志和数据文件是真正棘手和东西可以在许多方面会出问题。 无论如何尝试,让我知道这会有所帮助。
