Excel Jet 访问查询，模拟 vlookup
Excel Jet Access Query, Emulate a vlookup
我正在尝试将以下逻辑合并到我的查询中，这有点像 2 个 vlookup，如果一个不可用，请使用下一个。
=IFERROR(VLOOKUP(D2,'Segmentation'!$A:$C,3,0),IFERROR(VLOOKUP(C2,'Segmentation'!$A:$C,3,0),""))
所以它应该首先查找列 D (unit2) 然后如果没有查找列 C(value)
这是我目前所拥有的，我已经尝试了 OR 加入：
SELECT DISTINCT A.[unit], B.[Hierarchy] FROM [Mapping$] as A
inner join [Segmentation$] as B
ON (A.[unit2] = B.[Number] OR
A.[Value] = B.[Number])
WHERE B.[Hierarchy] <> ''
Order By A.[unit] asc
也尝试过：
SELECT DISTINCT A.[unit], B.[Hierarchy] FROM [Mapping$] as A
inner join [Segmentation$] as B
ON Nz(A.[unit2], A.[Value])=B.[Number]
WHERE B.[Hierarchy] <> ''
Order By A.[unit] asc
