问题
I am trying to convert the following excel formula to a Calculated Field in Access. Using Expressions or combination of a user defined expression with VBA code. any help appreciated! And appreciate any thoughts about data normalization, however this is not the issue. Thx
IF(SMALL(T319:V319,2)>6,SMALL(T319:V319,1),IF(SMALL(T319:V319,2)=0,LARGE(T319:V319,1),SMALL(T319:V319,2)
Cells T319 - V319 are fields in each record generated by a data query generated. call them A,B,C for this purpose.
回答1:
Suppose I presort the data so that from largest to smallest, the three values are represented by the letters I, J, and K. This means J is SMALL(T319:V319,2)
, K is SMALL(T319:V319,1)
and I is LARGE(T319:V319,1)
.
UPDATE: fixed the pseudocode and final section of the function. I misread the nested IFs of the Excel formula :P
The pseudo-code would be:
If J > 6 Then
return K
ElseIf J = 0 Then
return I
Else
return J
Are you sure this is what you want?
If so, you could make a VBA function as follows:
Public Function GetVal(A As Variant, B As Variant, C As Variant)
Dim I As Variant
Dim J As Variant
Dim K As Variant
'Sort the three values so A, B, C becomes sorted largest to smallest as I, J, K
If A > B Then
If A > C Then
I = A
If B > C Then
J = B
K = C
Else 'C > B
J = C
K = B
End If
Else 'C > A
I = C
J = A
K = B
End If
Else 'B > A
If B > C Then
I = B
If A > C Then
J = A
K = C
Else 'C > A
J = C
K = A
End If
Else 'C > B
I = C
J = B
K = A
End If
End If
'Use I, J, K to find the result
If J > 6 Then
GetVal = K
ElseIf J = 0 Then
GetVal = I
Else
GetVal = J
End If
End Function
