Question

有没有办法从使用PowerShell的SSIS目录中的软件包中获取Package XML，但是没有下载和解压缩项目？我想在XML文档中搜索某些字符串。

Answer 1

我没有运气尝试此代码的纯对象模型版本，因为我得到了error

使用“1”参数调用“Serialize”的异常：“参数'sink.Action'无效。”

超！在尝试通过托管对象模型进入项目之后，我试图通过TSQL路由。我们只需要模拟对SSISDB.catalog.get_project的调用并将其传递给文件夹和项目名称

Function Get-ProjectsTsql
{
    param
    (
        [Microsoft.SqlServer.Management.IntegrationServices.CatalogFolder] $folder
    ,   [string] $serverName = "localhost\dev2016"
    )

    # we want to build an execute procedure call that looks like this
    # exec [SSISDB].[catalog].[get_project] @folder_name=N'FolderName',@project_name=N'ProjectName'

    $connectionString = [String]::Format("Data Source={0};Initial Catalog=msdb;Integrated Security=SSPI;", $serverName)
    $connection = New-Object System.Data.SqlClient.SqlConnection($connectionString)
    $integrationServices = New-Object Microsoft.SqlServer.Management.IntegrationServices.IntegrationServices($connection)
    # The one, the only SSISDB catalog
    $catalog = $integrationServices.Catalogs["SSISDB"]

    #Instance of ProjectInfo
    foreach ($proj in $folder.Projects)
    {
        $projName = $proj.Name
        $folderName = $folder.Name

        $zipOut = "C:\tmp\$projName.zip"

        $query = "exec [SSISDB].[catalog].[get_project] @folder_name=N'$folderName',@project_name=N'$projName'"
        # Write-Host $query

        $command = New-Object System.Data.SqlClient.SqlCommand
        $command.CommandText = $query
        $command.Connection = $connection
        $projectBinary = $command.ExecuteScalar()
        [System.IO.File]::WriteAllBytes($zipOut,$projectBinary)
    }
}

Function Get-CatalogFolders
{
    param
    (
        [string] $serverName = "localhost\dev2012"
    )

    $connectionString = [String]::Format("Data Source={0};Initial Catalog=msdb;Integrated Security=SSPI;", $serverName)

    $connection = New-Object System.Data.SqlClient.SqlConnection($connectionString)

    $integrationServices = New-Object Microsoft.SqlServer.Management.IntegrationServices.IntegrationServices($connection)
    # The one, the only SSISDB catalog
    $catalog = $integrationServices.Catalogs["SSISDB"]

    $catalogFolders = $catalog.Folders

    return $catalogFolders
}

$serverName = "localhost\dev2016"
# Identify all the folders on the server
foreach ($folder in Get-CatalogFolders $serverName)
{
    # Save out all the projects to their zip files
    Get-ProjectsTsql $folder $serverName
}

这是我用.zip扩展名保存的ispac（因为它只是一个zip）。要获取包xml，您需要解压缩文件，找到您的包并从那里开始

Answer 2

虽然该线程已有几个月的历史，但我认为以下方法直接回答了原始问题。我遇到了类似的情况，我需要从SSISDB中的包访问XML，以作为新包的模板。好吧，在将项目字节读入我的脚本后，

var projectBytes = ssisServer.Catalogs["SSISDB"].Folders[SSISFolderName].Projects[SSISProjectName].GetProjectBytes();

可以通过从项目字节创建内存存档来绕过下载/解压缩。通过遍历存档条目直到找到正确的包（如果知道文件的索引更容易），最后一步是将存档条目读入流并将其传递给package.LoadFromXML方法。

Stream stream = new MemoryStream(projectBytes);

ZipArchive za = new ZipArchive(stream);

foreach (ZipArchiveEntry zipEntry in za.Entries)
{
    if (zipEntry.FullName == SSISPackageName)
    {
         Package pkg = new Package();

         StreamReader sr = new StreamReader(zipEntry.Open());

         pkg.LoadFromXML(sr.ReadToEnd(), null);

         break;

    }

}

Answer 3

如果目标是读取包中的数据并直接获取xml，那么包的XML代码实际上是作为二进制数据存储在SSISDB.internal.object_versions table.ref的object_data列中。[ 1]

您可以使用 GetSqlBinary 方法检索此数据。我已经看到了一个用于检索SSRS rdl文件的示例。见参考文献[2]有关代码的完整示例。

    # New BinaryWriter; existing file will be overwritten. 
    $fs = New-Object System.IO.FileStream ($name), Create, Write; 
    $bw = New-Object System.IO.BinaryWriter($fs); 

    # Read of complete Blob with GetSqlBinary 
    $bt = $rd.GetSqlBinary(2).Value; 
    $bw.Write($bt, 0, $bt.Length); 
    $bw.Flush(); 
    $bw.Close(); 
    $fs.Close();
