问题描述
我尝试使用 Restore-SqlDatabase cmdlet 来恢复数据库.我需要重新定位文件,但出现以下错误
I trying to restore a database by using the Restore-SqlDatabase cmdlet. I need to relocate the files but I'm getting the following errror
Restore-SqlDatabase : Cannot bind parameter 'RelocateFile'. Cannot convert the
"Microsoft.SqlServer.Management.Smo.RelocateFile" value of type
"Microsoft.SqlServer.Management.Smo.RelocateFile" to type
"Microsoft.SqlServer.Management.Smo.RelocateFile".
At line:25 char:108
+ ... e -RelocateFil $RelocateData
+ ~~~~~~~~~~~~~
+ CategoryInfo : InvalidArgument: (:) [Restore-SqlDatabase], ParameterBindingException
+ FullyQualifiedErrorId CannotConvertArgumentNoMessage,Microsoft.SqlServer.Management.PowerShell.RestoreSqlDatabaseCommand
我的 powershell 代码如下
My powershell code look like this
$RelocateData = New-Object Microsoft.SqlServer.Management.Smo.RelocateFile("MyDB_Data", "c:\data\MySQLServerMyDB.mdf")
$RelocateLog = New-Object Microsoft.SqlServer.Management.Smo.RelocateFile("MyDB_Log", "c:\data\MySQLServerMyDB.ldf")
$file = New-Object Microsoft.SqlServer.Management.Smo.RelocateFile($RelocateData,$RelocateLog)
$myarr=@($RelocateData,$RelocateLog)
Restore-SqlDatabase -ServerInstance DEV\DEMO -Database "test" -BackupFile $backupfile -RelocateFile $myarr
推荐答案
这看起来像是您加载的 SMO 版本与 Restore-SqlDatabase 期望的版本不同.这里可能有两种方法......
This looks like a difference in the version of SMO that you have loaded and the one that Restore-SqlDatabase expects. There are probably two approaches here...
- 确保版本匹配.
- 使用 Microsoft.SqlServer.Management.Smo.Restore.SqlRestore 方法而不是 Restore-SqlDatabase cmdlet.
我从下面的一个更大的脚本中提取了相关的部分.它在这种形式中未经测试,并且有一些变量,例如 $ServerName,假定它们可用,但它应该足以让您继续前进.
I have extracted the relevant pieces from a larger script below. It is untested in this form and there are a few variables such as $ServerName which are assumed to be available but it should be enough to get you going.
if($useSqlServerAuthentication)
{
$passwordSecureString = ConvertTo-SecureString -String $password -AsPlainText -Force;
$serverConnection = new-object Microsoft.SqlServer.Management.Common.ServerConnection $ServerName, $UserName, $passwordSecureString;
$server = new-object Microsoft.SqlServer.Management.Smo.Server $serverConnection;
}
else
{
$server = new-object Microsoft.SqlServer.Management.Smo.Server $ServerName;
}
$dataFolder = $server.Settings.DefaultFile;
$logFolder = $server.Settings.DefaultLog;
if ($dataFolder.Length -eq 0)
{
$dataFolder = $server.Information.MasterDBPath;
}
if ($logFolder.Length -eq 0)
{
$logFolder = $server.Information.MasterDBLogPath;
}
$backupDeviceItem = new-object Microsoft.SqlServer.Management.Smo.BackupDeviceItem $Path, 'File';
$restore = new-object 'Microsoft.SqlServer.Management.Smo.Restore';
$restore.Database = $DatabaseName;
$restore.Devices.Add($backupDeviceItem);
$dataFileNumber = 0;
foreach ($file in $restore.ReadFileList($server))
{
$relocateFile = new-object 'Microsoft.SqlServer.Management.Smo.RelocateFile';
$relocateFile.LogicalFileName = $file.LogicalName;
if ($file.Type -eq 'D'){
if($dataFileNumber -ge 1)
{
$suffix = "_$dataFileNumber";
}
else
{
$suffix = $null;
}
$relocateFile.PhysicalFileName = "$dataFolder\$DatabaseName$suffix.mdf";
$dataFileNumber ++;
}
else
{
$relocateFile.PhysicalFileName = "$logFolder\$DatabaseName.ldf";
}
$restore.RelocateFiles.Add($relocateFile) | out-null;
}
$restore.SqlRestore($server);
