vba 数组和 scripting.dictionary 中的 SUMIFS 更快

Question

我想使用 vba sumifs 数组和 scripting.dictionary 因为有十万条记录可能是最好的解决方案。 信息表“DBALL”是源，表“RECON”是结果。 我还在下面找到了 vba 代码，但它与结果不匹配。

信息公式表 "RECON" 列 B "In" = SUMIFS(DBALL:$A$2,$A$5:DBALL,$C$2,$C$5:RECON,$A2,DBALL!$B$2:$B$5,RECON !B$1)

信息公式表 "RECON" 列 c "Out" = SUMIFS(DBALL:$A$2,$A$5:DBALL,$C$2,$C$5:RECON,$A2,DBALL!$B$2:$B$5,RECON !C$1)

信息公式表“侦察”列 d“差异”= B2-C2

谢谢

正如评论中所说，使用 pivot 表可能是更好的解决方案。 电源 pivot。

如果您正在寻求 VBA 的解决方案并且想要使用字典，我可能会使用以下代码。

首先，您需要创建一个 class cVal来存储您所追求的值

Option Explicit

Public qtyIn As Double
Public qtyOut As Double

然后你可以使用下面的代码

Option Explicit

Sub useDict()

    Const COL_VAL = 1
    Const COL_INOUT = 2
    Const COL_COMBINE = 3
    Const GRO_IN = "IN"
    Const GRO_OUT = "OUT"

    Dim rg As Range, ws As Worksheet
    
    ' Get the range with the data
    Set ws = Worksheets("DBALL")
    Set rg = ws.Range("A1").CurrentRegion
    Set rg = rg.Offset(1, 0).Resize(rg.Rows.Count - 1)
        
    Dim vDat As Variant
    vDat = rg
    
    Dim dict As Object
    Set dict = CreateObject("Scripting.Dictionary")
    
    Dim Key As Variant, gro As Variant
    Dim i As Long, sngVal  As cVal
    For i = LBound(vDat, 1) To UBound(vDat, 1)
    
        ' Key of the dictionary
        Key = vDat(i, COL_COMBINE)
        ' trim the value and do not consider upper/lower case
        gro = UCase(Trim(vDat(i, COL_INOUT)))
                
        If dict.Exists(Key) Then
            ' just increase the "member" values of the already stored object
            Set sngVal = dict(Key)
            With sngVal
                If gro = GRO_IN Then
                    .qtyIn = .qtyIn + vDat(i, COL_VAL)
                End If
                If gro = GRO_OUT Then
                    .qtyOut = .qtyOut + vDat(i, COL_VAL)
                End If
            End With
        
        Else
            ' Create a new object which stores the summed values for "IN" resp "OUT"
            Set sngVal = New cVal
            With sngVal
                If gro = GRO_IN Then
                    .qtyIn = vDat(i, COL_VAL)
                End If
                If gro = GRO_OUT Then
                    .qtyOut = vDat(i, COL_VAL)
                End If
            End With
            dict.Add Key, sngVal

        End If
    
    Next i
    
    
    ' write Dictionary
    
    ' put the values of the dictionary in an array
    ' this is faster than writing each single line directly to the sheet
    ReDim vDat(1 To dict.Count, 1 To 4)
    i = 1
    For Each Key In dict.Keys
        vDat(i, 1) = Key
        vDat(i, 2) = dict(Key).qtyIn
        vDat(i, 3) = dict(Key).qtyOut
        vDat(i, 4) = Abs(dict(Key).qtyIn - dict(Key).qtyOut)
        i = i + 1
    Next Key
    
    'write Header
    Set rg = Worksheets("RECON").Range("A1")
    Set rg = rg.Resize(, 4)
    rg.Clear
    rg = Array("COMBINE", "In", "Out", "Diff")
        
    Set rg = Worksheets("RECON").Range("A2")
    Set rg = rg.Resize(dict.Count, 4)
    rg.Clear
    rg = vDat

End Sub

但我怀疑它是否比 Pivot 表更快
