SQL Recursive CTE 'where-used' / BOM explosion part 2 - sql

Question

Hi this carries on from another post,
SQL Recursive CTE 'where-used' / BOM explosion
which the original requirement was answered however I have realised I now have another final requirement. The data that I have after '1' i.e. description etc., want to repeat for each level so the description correctly identifies with the correct parent item. I tried just adding the columns in again in the final select however it just repeated items from level 1. How can this be done?
* UPDATE * I'm really struggling to get the test data/query to look how i want. I want to get the items to relate to each other through bomid. Output to look like img.
The relationship between BOM and BOMVERSION is one item has many BOMID's in BOM table each bomID has a corresponding record in BOMVERSION which through BOMID you get a different ITEMID off of BOMVERSION. That itemID can exist itself in the BOM table with MULTIPLE BOMIDs. I know this is confusing and is very difficult to demonstrate with test data. That's why i'm happy to put on bounty.
* UPDATE * through what i've learnt i've redone the query/test data. I haven't been able to get it to do EXACTLY what i want so query/data may need to be tweaked or added. I'll output what i'm expecting. Basically when BOM.ItemID is linked to BV.ItemID through BOMID i would expect BV.ItemID to be moved into next level and then if THAT BOM.ItemID links to another BV.ItemID move that item to the next level etc. etc. along with all other info RELATED to item in level.

Answer 2

I think You need this type of pivoting:
select p.MainItem, p.BVName
, left(p.[0],charindex('|',p.[0])-1) Level0_ID, REPLACE(p.[0], left(p.[0],charindex('|',p.[0])),'') Level0_Decription
, left(p.[1],charindex('|',p.[1])-1) Level1_ID, REPLACE(p.[1], left(p.[1],charindex('|',p.[1])),'') Level1_Decription
, left(p.[2],charindex('|',p.[2])-1) Level2_ID, REPLACE(p.[2], left(p.[2],charindex('|',p.[2])),'') Level2_Decription
, left(p.[3],charindex('|',p.[3])-1) Level3_ID, REPLACE(p.[3], left(p.[3],charindex('|',p.[3])),'') Level3_Decription
, left(p.[4],charindex('|',p.[4])-1) Level4_ID, REPLACE(p.[4], left(p.[4],charindex('|',p.[4])),'') Level4_Decription
, left(p.[5],charindex('|',p.[5])-1) Level5_ID, REPLACE(p.[5], left(p.[5],charindex('|',p.[5])),'') Level5_Decription
, left(p.[6],charindex('|',p.[6])-1) Level6_ID, REPLACE(p.[6], left(p.[6],charindex('|',p.[6])),'') Level6_Decription
, left(p.[7],charindex('|',p.[7])-1) Level7_ID, REPLACE(p.[7], left(p.[7],charindex('|',p.[7])),'') Level7_Decription
from (select t.MainItem, t.BVName, t.level, convert(varchar(20),t.ParentItem)+'|'+t.ParentItemName item from tree t) t
pivot (max(item) for t.level in ([0], [1], [2], [3], [4], [5], [6], [7])) p
If You want use more column to pivot the try this:
select p.MainItem, p.BVName
, p.Level0_ParentItem, p.Level0_ParentItemName
, p.Level1_ParentItem, p.Level1_ParentItemName
, p.Level2_ParentItem, p.Level2_ParentItemName
, p.Level3_ParentItem, p.Level3_ParentItemName
, p.Level4_ParentItem, p.Level4_ParentItemName
, p.Level5_ParentItem, p.Level5_ParentItemName
, p.Level6_ParentItem, p.Level6_ParentItemName
, p.Level7_ParentItem, p.Level7_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
, Level2_ParentItem, Level2_ParentItemName
, Level3_ParentItem, Level3_ParentItemName
, Level4_ParentItem, Level4_ParentItemName
, Level5_ParentItem, Level5_ParentItemName
, Level6_ParentItem, Level6_ParentItemName
, Level7_ParentItem, Level7_ParentItemName
)) p
In the unpivot statement I make the new columns for the pivot statement.
