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
