BOM递归CTE /输入数据以完成查询

Question

我做了递归cte查询以获取特定零件编号的材料清单，但我需要的是要问我哪个零件号需要BOM。它工作正常，如果我不能轻易查询不同的部件号，它就不起作用。

查询如下：

WITH BOM_CTE(COMPONENT, PARENT,QTY,LVL)

AS (SELECT i.fcomponent, i.fparent, i.fqty, 1 AS LVL

FROM dbo.inboms AS i INNER JOIN dbo.invcur ON i.fparent = dbo.invcur.fcpartno
AND i.fparentrev = dbo.invcur.fcpartrev INNER JOIN dbo.inmastx ON dbo.invcur.fcpartno
=dbo.inmastx.fpartno AND dbo.invcur.fcpartrev = dbo.inmastx.frev

WHERE(i.fparent = '124-5130')

UNION ALL

SELECT     i.fcomponent, i.fparent, i.fqty, BOM_CTE_1.LVL + 1 AS INC_LVL

FROM dbo.inboms AS i INNER JOIN BOM_CTE AS BOM_CTE_1 ON i.fparent=BOM_CTE_1.COMPONENT)



SELECT     B.PARENT, B.COMPONENT, B.QTY, B.LVL
FROM         BOM_CTE AS B LEFT OUTER JOIN
                        BOM_CTE AS C ON B.PARENT = C.COMPONENT
 GROUP BY B.PARENT, B.COMPONENT, B.QTY, B.LVL
 ORDER BY B.LVL

正如您所看到的，CTE第一部分中的WHERE子句将给出结果，但是这个查询不能用Excel在图形上表示，因此我不能使用参数来请求部件号。

关于如何实现这一目标的任何想法？
