Question

我正在使用SQL Server 2016为Microsoft BI项目实施devops管道，主要使用VSTS和PowerShell。对于SSIS的发布流程，我使用integration services assembly所述的here。

我遇到问题让Remove method from the assembly正常工作。我希望开发人员能够在SSDT中的XML文件中定义变量，并且发布PowerShell脚本以删除变量（如果它存在（并且XML中的值不同）。然后将使用新值重新创建（我可以看到单个变量上没有alter方法）。

这是一个代码示例，它简化了我想要做的事情：

$FolderName = "VariablesTest1"
$EnvironmentName = "Development"

# Load the IntegrationServices Assembly
[System.Reflection.Assembly]::LoadWithPartialName("Microsoft.SqlServer.Management.IntegrationServices") | Out-Null;

# Store the IntegrationServices Assembly namespace
$ISNamespace = "Microsoft.SqlServer.Management.IntegrationServices"

# Create a connection to the server
$sqlConnectionString = "Data Source=localhost;Initial Catalog=master;Integrated Security=SSPI;"
$sqlConnection = New-Object System.Data.SqlClient.SqlConnection $sqlConnectionString

# Create the Integration Services object
$integrationServices = New-Object $ISNamespace".IntegrationServices" $sqlConnection

$catalog = $integrationServices.Catalogs["SSISDB"]
$folder = $integrationServices.Catalogs["SSISDB"].Folders[$FolderName]

# Creates the folder
$folder = New-Object $ISNamespace".CatalogFolder" ($catalog, $FolderName, "Folder description")
      $folder.Create()

$environment = $folder.Environments[$EnvironmentName]

# Creates the Environment
$environment = New-Object $ISNamespace".EnvironmentInfo" ($folder, $EnvironmentName, "Description")
    $environment.Create()

# Add the variable to the environment
$environment.Variables.Add("Variable2", "String", "MyValue", $false, "This is my variable")
$environment.Alter()

# Print the variable to make sure it exists
Write-Host $environment.Variables.Name

# Delete the variable
$environment.Variables.Remove("Variable2")

这将在Integration Services目录中创建所需的对象，并应创建，然后删除变量，但不会。变量已创建但未删除。

我是在错误的地方调用remove方法还是其他的？

Answer 1

在您删除后，您似乎错过了额外的$ environment.Alter（）！

# Delete the variable
$environment.Variables.Remove("Variable2")
$environment.Alter()

使用PowerShell删除SSIS变量
