用于多个条件的 Excel VBA 嵌套案例函数

Question

我有一个 sql 查询并想在 Excel VBA 中进行复制。我在使用多个 case 语句时遇到问题

示例列

column(a) - segment_nbr

column(b) - ltv 

segment_nbr ltv 

1   2.1526521   
4   3.01348283  
1   1.49385324  
1   1.84731871  
1   1.29541322  
1   0.55659018  
2   2.33690417  
1   1.34068404  
2   1.54078719  
1   0.74087837  
3   1.93278303  
1   1.38347042  
4   1.64194326  

我想构建一个函数来复制以下嵌套 if /case 公式的示例：

=if(and($A1=1,$B1<=0.9),100.01,IF(and($A1=1,$B1<=2.0),201.01,IF(and($A1=1,$B1<=3.0),-23.26,IF(and($A1=2,$B1<=0.9),-99.98,IF(and($A1=3,$B1<=1.3),199.98, IF(and($A1=4,$B1<=0.44),-32.43,IF(and($A1=4,$B1<=1.6),160.9,"" )))

我尝试了以下但没有工作：它没有使用 segment_nb 参数。

有什么想法可以纠正吗？

Function ltv_w(segment_nbr, ltv )

Select Case ltv 
    Case Is <= 0.9 And segment_nbr = 1
        ltv_w = 100.01
    Case Is <= 2.0 And segment_nbr = 1
        ltv_w = 201.01
    Case Is <= 3.0 And segment_nbr = 1
        ltv_w = -23.26
    Case Is <= 0.9 And segment_nbr = 2
        ltv_w = -99.98
    Case Is <= 1.3 And segment_nbr = 3
        ltv_w = 199.98
    Case Is <= 0.44 And segment_nbr = 4
        ltv_w = -32.43
    Case Is <= 1.6 And segment_nbr = 4
        ltv_w = 160.9

End Select

End Function

Answer 1

首先 - 更改检查顺序。
在第一个案例级别检查segment_nbr，然后在第二个级别检查ltv。

Function ltv_w(segment_nbr, ltv)

    Select Case segment_nbr
        Case 1
            Select Case ltv
                Case Is <= 0.9: ltv_w = 100.01
                Case Is <= 2#:  ltv_w = 201.01
                Case Is <= 3#:  ltv_w = -23.26
            End Select

        Case 2
        Case 3
        Case 4
    End Select
End Function

小心Case Is <= 序列。

再一次...... 永远不要比较双打的平等。
所以像<= 3#这样的条件需要转换成Not > 3#。

Answer 2

使用Select Case ltv，只检查ltv的值，不像使用If并添加And，它忽略了第二个条件。

你可以稍微“欺骗”Select Case，你可以使用Select Case True，然后在下面嵌套修改你的代码：

Case ltv <= 0.9 And segment_nbr = 1

试试下面的代码：

Function ltv_w(segment_nbr, ltv)

Select Case True
    Case ltv <= 0.9 And segment_nbr = 1
        ltv_w = 100.01
    Case ltv <= 2# And segment_nbr = 1
        ltv_w = 201.01
    Case ltv <= 3# And segment_nbr = 1
        ltv_w = -23.26
    Case ltv <= 0.9 And segment_nbr = 2
        ltv_w = -99.98
    Case ltv <= 1.3 And segment_nbr = 3
        ltv_w = 199.98
    Case ltv <= 0.44 And segment_nbr = 4
        ltv_w = -32.43
    Case ltv <= 1.6 And segment_nbr = 4
        ltv_w = 160.9
End Select

End Function

根据我的理解，你也可以用 if else 语句来实现这个东西，检查下面的代码它根据你的 excel 公式修改。

''''
Function ltv_w(segment_nbr, ltv)

Select Case segment_nbr
    Case Is = 1

    Select Case ltv
    Case Is <= 0.9
    ltv_w = -99.98

    Case Is <= 2#
    ltv_w = 201.01

    Case Is <= 3#
    ltv_w = -23.26

    Case Else
    ltv_w = ""

    End Select

    Case Is = 2

    Select Case ltv
    Case Is <= 0.9
    ltv_w = -99.98

    Case Else
    ltv_w = ""

    End Select

    Case Is = 3

    Select Case ltv
    Case Is <= 1.3
    ltv_w = 199.98

    Case Else
    ltv_w = ""

    End Select

    Case Is = 4

    Select Case ltv
    Case Is <= 0.44
    ltv_w = -32.43

    Case Is <= 1.6
    ltv_w = 160.9

    Case Else
    ltv_w = ""

    End Select

Case Else
ltv_w = ""

End Select
End Function
