SQL 递归 CTE 'where-used' / BOM 展开第 2 部分
SQL Recursive CTE 'where-used' / BOM explosion part 2
嗨，这是从另一个post，
最初的要求已得到回答，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，想要为每个级别重复，以便描述正确地标识正确的父项。我尝试在最后的 select 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 data/query 看起来像我想要的那样。我想让项目通过 bomid 相互关联。输出看起来像 img.
BOM和BOMVERSION之间的关系是一个item在BOM中有多个BOMID table每个bomID在BOMVERSION中都有对应的记录，通过BOMID可以得到与BOMVERSION不同的ITEMID。该 itemID 本身可以存在于具有多个 BOMID 的 BOM table 中。我知道这很令人困惑，而且很难用测试数据来证明。这就是为什么我很乐意悬赏。
* 更新 * 根据我所学，我重做了 query/test 数据。我无法让它完全按照我的意愿行事，因此 query/data 可能需要调整或添加。我会输出我所期待的。基本上当 BOM.ItemID 通过 BOMID 链接到 BV.ItemID 时，我希望 BV.ItemID 被移动到下一个级别，然后如果 BOM.ItemID 链接到另一个 BV.ItemID 移动那个项目到下一个级别等等，以及与级别中的项目相关的所有其他信息。

pivot (max(item) for t.level in ([0], [1], [2], [3], [4], [5], [6], [7])) p
如果您想使用更多的列来旋转，试试这个：
select p.MainItem, p.BVName
, p.Level0_ParentItem, p.Level0_ParentItemName
, p.Level1_ParentItem, p.Level1_ParentItemName
, p.Level2_ParentItem, p.Level2_ParentItemName

from (
select u.MainItem, u.BVName, 'Level'+convert(varchar(30), u.level)+'_'+u.col col, u.value
from (select t.MainItem, t.BVName, t.level, convert(nvarchar(max),t.ParentItem) ParentItem, convert(nvarchar(max),t.ParentItemName) ParentItemName from tree t) t /*Convert all columns to the desired, but the same type*/
unpivot (value for col in (ParentItem, ParentItemName /*and the other columns You want use*/)) u) src
pivot (max(src.value)
for src.col in (
Level0_ParentItem, Level0_ParentItemName
, Level1_ParentItem, Level1_ParentItemName

, Level3_ParentItem, Level3_ParentItemName
, Level4_ParentItem, Level4_ParentItemName
, Level5_ParentItem, Level5_ParentItemName
, Level6_ParentItem, Level6_ParentItemName
, Level7_ParentItem, Level7_ParentItemName
)) p
在 unpivot 语句中，我为 pivot 语句创建了新列。

如果您想使用更多的列来旋转，试试这个：

from (

from (select t.MainItem, t.BVName, t.level, convert(nvarchar(max),t.ParentItem) ParentItem, convert(nvarchar(max),t.ParentItemName) ParentItemName from tree t) t /*Convert all columns to the desired, but the same type*/
unpivot (value for col in (ParentItem, ParentItemName /*and the other columns You want use*/)) u) src
pivot (max(src.value)
for src.col in (

, Level5_ParentItem, Level5_ParentItemName

在 unpivot 语句中，我为 pivot 语句创建了新列。 此解决方案的更多内容：SQL Server Pivot Table with multiple column aggregates
