我正在创建一个框架，用于从 MVC 应用程序启动和监视 SSIS 包。我的大部分工作都在工作，我正试图改进我的监视器功能，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，不允许我识别序列及其相关步骤。
我想做的是创建 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，并且与目前不同的是，只能在平面表中显示它，我应该能够将序列步骤放在里面一个序列，并为用户提供有关流程所在位置的更好反馈。
我将用于定义包的日志条目示例（我将使用以前运行的实例中的条目来获取定义）如下所示：

我之前已经创建了查询，该查询具有表中字段的父子关系，但为此我需要识别出现在同一 sourceid 的 PackageStart 和 PackageEnd 或 OnPreExecute 和 OnPostExecute 事件之间的所有记录。
这还需要过滤为仅使用特定的 executionid，以便您分析包的一个实例（很容易在给定的 sourceid 和 PackageEnd 事件的 id 列上使用最大值，您可以识别单个 executionid）。
关于如何在 SQL 语句中将这些拼凑在一起的任何想法，因为这现在有点超出我的知识范围？
