我尝试使用SQL和SSIS中的组件从.NET应用程序启动ETL过程。除了创建一个调用存储过程的按钮（包括传入参数）之外，我对.NET应用程序没有任何影响。该应用程序需要SQL Server登录才能连接到数据库。
我遇到的问题是我无法使用SQL登录启动SSIS包（需要Windows登录），并且应用程序无法使用Windows登录（需要SQL登录）。我该如何围绕这个圆圈？
更多细节
该应用程序正在管理数十个仓库维度，每个维度都使用自己的ETL流程。代码的设计是将Table_ID传递给存储过程，该过程创建并启动SSIS执行以运行导入。然后，在SQL中完成ETL的其余部分。一个非常简化的动态SQL脚本看起来就像下面那样，动态SQL的输出显示在：

应该可以根据解释here代表其他用户或组运行脚本。很快解释它必须看起来像这样：
IMPERSONATE grant 答案 1 :(得分：1)
感谢您的回复。但是，在尝试实现它们时，我没有取得任何成功，特别是围绕脚本的SSIS元素。
我运行以下内容......
--[domain/windowsuser] has sysadmin server role, but no explicit user asigned to individual databases
USE [DataMart_ICT]
CREATE USER [domain/windowsuser] FOR LOGIN [domain/windowsuser]
ALTER ROLE [db_owner] ADD MEMBER [domain/windowsuser]
CREATE USER [DBF_App_Admin] FOR LOGIN [DBF_App_Admin]
ALTER ROLE [db_owner] ADD MEMBER [DBF_App_Admin]
GRANT IMPERSONATE ON USER::[domain/windowsuser] TO [DBF_App_Admin]
...尝试运行我之前介绍的代码的这个小节（导致问题的位）......
USE [DataMart_ICT]
GO
EXECUTE AS LOGIN = 'domain/windowsuser'
-----------------------------------------
DECLARE @execution_id bigint
DECLARE @SSISStatus int
EXEC [SSISDB].[catalog].[create_execution] @package_name = N'ActiveDirectoryUser_2001.dtsx',
@execution_id = @execution_id OUTPUT,
@folder_name = N'Trinity',
@project_name = N'DataMart_ICT',
@use32bitruntime = 'FALSE',
@reference_id = Null
EXEC [SSISDB].[catalog].[set_execution_parameter_value] @execution_id,
@object_type = 50,
@parameter_name = N'SYNCHRONIZED',
@parameter_value = 1
EXEC [SSISDB].[catalog].[start_execution] @execution_id
--Execution has failed if SSISDB status <> 7
SELECT @SSISStatus = [Status] FROM [SSISDB].[catalog].[executions] WHERE [execution_id] = @execution_id
USE [DataMart_ICT]
GO
REVERT
...并收到以下错误：
The current security context cannot be reverted. Please switch to the original database where 'Execute As' was called and try it again.
问题似乎与EXEC [SSISDB]。[目录]。[start_execution]有关。如果我注释掉这一行就行了。看看这个（MS Built and defined）程序，它已经包含了自己的EXECUTE AS和REVERT，我显然无法改变它。
如果我调用[msdb]。[dbo]。[sp_start_job]，我会遇到类似的问题，如果我要调用启动SSIS包的SQL作业，我将需要它。
