我正在创建一个框架，用于从MVC应用程序启动和监视SSIS包。我的大部分都在工作，我只是在尝试改进我的显示器功能，以便我可以在浏览器中显示包的表示。我已经能够创建一个能够唯一标识包的所有“源”组件的查询，但这只是一个平面表示，并且不允许我识别序列及其相关步骤，例如。
我希望能够创建一个SSIS日志表的分层查询，它将提供如下表示：
Package Start
Step 1
Sequence A
Step A1
Step A2
Sequence B
Step B1
Step B2
Step 2
Sequence C
Step C1
Step C2
Step C3
Step 4
Step 5
Package End
通过能够创建层次结构，我希望能够在浏览器中创建包的表示，并且与当前不同，只能在平面表中显示它，如结构，我应该能够放置序列中的序列步骤，并为用户提供有关过程所在位置的更好反馈。
我将用于定义包的日志条目示例（我将使用先前运行的实例中的条目来获取定义）如下所示：

我之前创建的查询在表中具有字段的父子关系，但为此我需要识别出在相同sourceid的PackageStart和PackageEnd或OnPreExecute和OnPostExecute事件之间出现的所有记录。 / p>
这还需要进行过滤以仅使用特定的executionid，以便分析包的一个实例（对于给定的sourceid，可以轻松地在id列上使用max，并且可以识别单个executionid的PackageEnd事件）。
关于如何在SQL语句中将其拼凑在一起的任何想法，因为现在这有点超出我的知识领域？
