Question

我有一个使用Azure数据工厂在Azure SQL数据库上提取数据，处理和泵送数据的过程。最后，SSAS表格模型使用来自Azure SQL的数据。到目前为止，使用Azure Data Factory v2自动化将数据泵送到Azure SQL的整个过程都是自动化的，但是我无法找到一种自动处理SSAS表格模型的方法。请让我知道是否有办法做到这一点。

我希望ADF v2以某种方式触发它，以便表格在新数据被泵入SQL后立即获取更新的数据。由于我无法使用ADF v2进行此操作，因此尝试使用Powershell。我在这里面临的障碍是，我需要传递两个凭据来处理表格 1. Azure SQL的SQL Server身份验证 2.一名模拟用户的Windows凭据我是Powershell的新手，在通过这两个凭据时遇到问题

Powershell脚本：-

$Transactional="Y", $Parallel="Y",$MaxParallel=2,$MaxCmdPerBatch=1, $PrintCmd="N",
