SQL 递归 CTE 'where-used'/BOM 爆炸第 2 部分

嗨，这是从另一篇文章继续的，

SQL Recursive CTE 'where-used' / BOM explosion

最初的要求已得到解答，但我意识到我现在还有另一个最终要求。我在“1”之后拥有的数据(即描述等)希望对每个级别重复，以便描述正确地识别正确的父项。我尝试在最终选择中再次添加列，但它只是重复了级别 1 中的项目。如何做到这一点？

* 更新 * 我真的很难让测试数据/查询看起来像我想要的那样。我想让这些项目通过 bomid 相互关联。输出看起来像 img。

BOM和BOMVERSION之间的关系是一个项目在BOM表中有多个BOMID，每个bomID在BOMVERSION中都有对应的记录，通过BOMID您可以从BOMVERSION中获得不同的ITEMID。该 itemID 本身可以存在于具有多个 BOMID 的 BOM 表中。我知道这很令人困惑，并且很难用测试数据来证明。这就是为什么我很高兴获得赏金。

*更新*根据我所了解到的，我已经重做了查询/测试数据。我无法让它完全执行我想要的操作，因此可能需要调整或添加查询/数据。我会输出我所期望的。基本上，当 BOM.ItemID 通过 BOMID 链接到 BV.ItemID 时，我希望 BV.ItemID 移动到下一个级别，然后如果该 BOM.ItemID 链接到另一个 BV.ItemID 则将该项目移动到下一个级别等等。以及与关卡中的项目相关的所有其他信息。
