Restore-SqlDatabase cmdlet中的RelocateFile属性的问题

Question

我尝试使用Restore-SqlDatabase cmdlet还原数据库.我需要重新定位文件,但我得到以下错误

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代码看起来像这样

$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

Answer 1

对于解决方案#1,您需要在实例化重定位文件以使用正确的程序集时指定程序集限定名称.

$RelocateData = New-Object 'Microsoft.SqlServer.Management.Smo.RelocateFile, Microsoft.SqlServer.SmoExtended, Version=11.0.0.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91' -ArgumentList "MyDB_Data", "c:\data\MySQLServerMyDB.mdf"
$RelocateLog = New-Object 'Microsoft.SqlServer.Management.Smo.RelocateFile, Microsoft.SqlServer.SmoExtended, Version=11.0.0.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91' -ArgumentList "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

希望能帮助到你 !

您可以通过与版本无关的方式执行此操作:

$sqlServerSnapinVersion = (Get-Command Restore-SqlDatabase).ImplementingType.Assembly.GetName().Version.ToString()
$assemblySqlServerSmoExtendedFullName = "Microsoft.SqlServer.SmoExtended, Version=$sqlServerSnapinVersion, Culture=neutral, PublicKeyToken=89845dcd8080cc91"

$RelocateData = New-Object "Microsoft.SqlServer.Management.Smo.RelocateFile, $assemblySqlServerSmoExtendedFullName"('MyDB_Data', 'c:\data\MySQLServerMyDB.mdf')
$RelocateLog = New-Object "Microsoft.SqlServer.Management.Smo.RelocateFile, $assemblySqlServerSmoExtendedFullName"('MyDB_Log', 'c:\data\MySQLServerMyDB.ldf')
$myarr=@($RelocateData,$RelocateLog)
Restore-SqlDatabase -ServerInstance DEV\DEMO -Database "test" -BackupFile $backupfile -RelocateFile $myarr

这看起来与您加载的SMO版本和Restore-SqlDatabase期望的版本不同.这里可能有两种方法......

1. 确保版本匹配.
2. 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.它是以这种形式未经测试的,并且有一些变量,例如$ ServerName,它们被认为是可用的,但它应该足以让你前进.

    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);

使用@Linhares 解决方案，但 Snapin 程序集的版本 15.0.0.0 与引用的 Microsoft.SqlServer.SmoExtended 版本 15.100.0.0 不匹配。

因此调整了这一行以直接从引用的程序集中获取版本。

$sqlServerSnapinVersion = ((Get-Command Restore-SqlDatabase).ImplementingType.Assembly.GetReferencedAssemblies() | ? { $_.Name -eq "Microsoft.SqlServer.SmoExtended" }).Version.ToString()
