Sql server 我需要链接表dbo.RMY_LEAD_TIME，并获取var项的.stocklevel和.LeadTime_天

我想我需要一个嵌套选择来捕获RMY_LEAD_TIME的信息。此功能将获取提前期天数或库存水平

我可以复制此跳过的函数。我写这篇文章是为了获取项目编号，现在我想修改它以从另一个表中获取相应的信息。物料编号与另一张表上的物料编号匹配

SET ANSI_NULLS OFF
GO
SET QUOTED_IDENTIFIER OFF
GO

CREATE FUNCTION [dbo].[udf_BuildPartNumber]
     (@storeNo varchar(5), @shipDate datetime, @carNo varchar(50))
RETURNS varchar(2000) 
AS
BEGIN
    DECLARE @items varchar(2000)

    SELECT 
        @items = ISNULL(@items + '^','') + im.ITEM_NUMBER
    FROM 
        dbo.TRANSFERS t
    LEFT OUTER JOIN 
        MatDump.dbo.ITM_MSTR im ON SUBSTRING(t.cic, 1,9) + '0' =  im.CIC  
    INNER JOIN 
        dbo.TRANSFER_CARS tc ON t.TRANSFER_ID = tc.TRANSFER_ID
    WHERE 
        t.date_shipped = @shipDate 
        AND t.TO_STORE_ID = @storeNo 
        AND tc.CAR_NUM = @carNo
    ORDER BY 
        t.SEQ_OR_ID_NUM 

    RETURN @items END

我调用这两个函数从RMY_LEAD_时间表返回Stocklevel和LeadTime。肖恩·兰格，谢谢你的建设性批评。当我试图完善我的问题时，我能够更好地自己做研究并得到答案。再次感谢。

这里有什么问题？似乎您有一个函数，出于某种原因您想更改它，但正如发布的消息所示，您在此处尝试执行的操作一点也不清楚。此函数返回ITEM_NUMBER，我需要使用ITEM_NUMBER在尚未使用的表上交叉引用Material_NUMBER。当我尝试编写新的select时，我得到一个错误嗯…我不知道你的表结构是什么样的，我甚至不知道你试图使用的是什么表，我不知道你得到的错误消息是什么。现在，你的问题就像把你的车带到修理厂，说你想对它进行改装，但没有提供任何你想要的细节。除非您能提供一些详细信息，否则我们无法提供帮助。表1 RMY\U交付周期有物料编号、库存级别。表2传输有CIC参考号、序列号或ID号、到存储号、发货日期、传输号、表3传输号、车有传输号、车号、表4 ITM主控器有项目号，该功能可以正确工作，只要给我汽车库存中每个项目的相应零件号。我想尝试获取该零件号，并从RMY_LEAD_TIME获得每个项目的重新进货水平。通过将@partNum与RMY_LEAD_TIME.MaterialNumber进行比较，我可以获得该项目的重新进货水平。
