所以我写了下面的查询，但是我遇到了结果集的问题。我目前知道如何解决这个问题的唯一方法是创建MULTIPLE视图，并做几个左连接，但我怀疑这是效率最低的方法。我需要抓住一些行并将它们转换为列，我只是不知道该怎么做。
use TSTCO
GO
select job.MANUFACTUREORDER_I as MONumber, job.ENDDATE as DueDate, job.ITEMNMBR, item.ITEMDESC, MANUFACTUREORDPRI_I as MOPriority, bom.CPN_I,
item2.ITEMDESC
from WO010032 job
left join iv00101 item on job.ITEMNMBR=item.ITEMNMBR
left join BM010115 bom on bom.PPN_I = job.ITEMNMBR and bom.BOMNAME_I = job.BOMNAME_I
left join iv00101 item2 on bom.CPN_I = item2.ITEMNMBR
where MANUFACTUREORDER_I like '2007-13580'
and (item2.itemdesc like '10:%' or item2.itemdesc like '09:%' or item2.itemdesc like '101:%' or item2.itemdesc like '12:%' or item2.itemdesc like '13:%' or item2.itemdesc like '131:%' or item2.itemdesc like '14:%' or item2.itemdesc like '15:%' or item2.itemdesc like '16:%' or item2.itemdesc like '17:%' or item2.itemdesc like '18:%' or item2.itemdesc like '21:%' or item2.itemdesc like '22:%' or item2.itemdesc like '23:%' or item2.itemdesc like '24:%')
Order by item2.Itemdesc
我当前的结果集如下所示：
MONumber DueDate ITEMNMBR ITEMDESC MOPriority CPN_I ITEMDESC

我希望它看起来像：
MONumber DueDate ITEMNMBR ITEMDESC MOPriority FABRIC Graphic Panel A Panel B Panel C Neck Trim Flatlock Thread
------------------------------- ----------------------- ------------------------------- --------------------------------- ---------- --------------------------------- --------------------------------- -------------------- -------------------- -------------------- ------------------- --------------------------------

我不希望任何人为我做任何事情，但一些指导会非常感激。我认为Pivot可能是我需要开始的地方，但我不太确定。当我看一下PIVOT语法时，我不确定从哪里开始。从第一个代码块可以看出，列总是以某些数字开头，就像结构总是以“10：”开头。数字后面的文字是变化的部分，我需要返回。一些列最终会变成“NULL”也不值得，因为并非一切都会有颈部修剪等。
提前感谢您的帮助。
