将唯一值填充到Excel中的VBA数组中

Question

任何人都可以向我提供VBA代码，该代码将从Excel工作表中获取范围（行或列）并使用唯一值填充列表/数组， 即：

table
table
chair
table
stool
stool
stool
chair

当宏运行时会创建一个类似的数组：

fur[0]=table
fur[1]=chair
fur[2]=stool

Answer 1

Sub GetUniqueAndCount()

    Dim d As Object, c As Range, k, tmp As String

    Set d = CreateObject("scripting.dictionary")
    For Each c In Selection
        tmp = Trim(c.Value)
        If Len(tmp) > 0 Then d(tmp) = d(tmp) + 1
    Next c

    For Each k In d.keys
        Debug.Print k, d(k)
    Next k

End Sub

Answer 2

在这种情况下，我总是使用这样的代码（只要确保你选择的分类不是搜索范围的一部分）

Dim tmp As String
Dim arr() As String

If Not Selection Is Nothing Then
   For Each cell In Selection
      If (cell <> "") And (InStr(tmp, cell) = 0) Then
        tmp = tmp & cell & "|"
      End If
   Next cell
End If

If Len(tmp) > 0 Then tmp = Left(tmp, Len(tmp) - 1)

arr = Split(tmp, "|")

Answer 3

将蒂姆的词典方法与下面的Jean_Francois的变体数组相结合。

您想要的数组位于objDict.keys

Sub A_Unique_B()
Dim X
Dim objDict As Object
Dim lngRow As Long

Set objDict = CreateObject("Scripting.Dictionary")
X = Application.Transpose(Range([a1], Cells(Rows.Count, "A").End(xlUp)))

For lngRow = 1 To UBound(X, 1)
    objDict(X(lngRow)) = 1
Next
Range("B1:B" & objDict.Count) = Application.Transpose(objDict.keys)
End Sub

Answer 4

这是老派的做法。

它将比循环遍历单元格（例如For Each cell In Selection）更快地执行，并且无论如何都是可靠的，只要你有一个矩形选择（即不是Ctrl-选择一堆随机单元格）。

Sub FindUnique()

    Dim varIn As Variant
    Dim varUnique As Variant
    Dim iInCol As Long
    Dim iInRow As Long
    Dim iUnique As Long
    Dim nUnique As Long
    Dim isUnique As Boolean

    varIn = Selection
    ReDim varUnique(1 To UBound(varIn, 1) * UBound(varIn, 2))

    nUnique = 0
    For iInRow = LBound(varIn, 1) To UBound(varIn, 1)
        For iInCol = LBound(varIn, 2) To UBound(varIn, 2)

            isUnique = True
            For iUnique = 1 To nUnique
                If varIn(iInRow, iInCol) = varUnique(iUnique) Then
                    isUnique = False
                    Exit For
                End If
            Next iUnique

            If isUnique = True Then
                nUnique = nUnique + 1
                varUnique(nUnique) = varIn(iInRow, iInCol)
            End If

        Next iInCol
    Next iInRow
    '// varUnique now contains only the unique values. 
    '// Trim off the empty elements:
    ReDim Preserve varUnique(1 To nUnique)
End Sub

Answer 5

好的，我终于做到了：

Sub CountUniqueRecords()
Dim Array() as variant, UniqueArray() as variant, UniqueNo as Integer,      
Dim i as integer, j as integer, k as integer

Redim UnquiArray(1)

k= Upbound(array)

For i = 1 To k
For j = 1 To UniqueNo + 1
  If Array(i) = UniqueArray(j) Then GoTo Nx
Next j
  UniqueNo = UniqueNo + 1
  ReDim Preserve UniqueArray(UniqueNo + 1)
  UniqueArray(UniqueNo) = Array(i)
Nx:
Next i

MsgBox UniqueNo

End Sub

Answer 6

此VBA函数在传递范围或2D数组源时返回不同值的数组

默认情况下，处理源的第一列，但您可以选择选择另一列。

我为此写了LinkedIn article。

MainActivity.Java

Answer 7

通过MS Excel 365功能UNIQUE()

为了丰富上述有效的解决方案，

Sub ExampleCall()
Dim rng As Range: Set rng = Sheet1.Range("A2:A11")   ' << change to your sheet's Code(Name)
Dim a: a = rng
a = getUniques(a)
arrInfo a
End Sub

Function getUniques(a, Optional ZeroBased As Boolean = True)
Dim tmp: tmp = Application.Transpose(WorksheetFunction.Unique(a))
If ZeroBased Then ReDim Preserve tmp(0 To UBound(tmp) - 1)
getUniques = tmp
End Function

Answer 8

老派的方法是我最喜欢的选择。谢谢。它确实很快。但我没有使用redim。这里虽然是我的真实世界的例子，我在列中找到每个唯一“密钥”的值，并将其移动到一个数组中（比如对于员工而言，值是每天工作的小时数）。然后，我将每个键及其最终值放入活动工作表上的总计区域。我已经对那些想要了解这里发生的事情的痛苦细节的人进行了广泛的评论。此代码完成了有限的错误检查。

Sub GetActualTotals()
'
' GetActualTotals Macro
'
' This macro accumulates values for each unique employee from the active
' spreadsheet.
'
' History
' October 2016 - Version 1
'
' Invocation
' I created a button labeled "Get Totals" on the Active Sheet that invokes
' this macro.
'
Dim ResourceName As String
Dim TotalHours As Double
Dim TotalPercent As Double
Dim IsUnique As Boolean
Dim FirstRow, LastRow, LastColumn, LastResource, nUnique As Long
Dim CurResource, CurrentRow, i, j As Integer
Dim Resource(1000, 2) As Variant
Dim Rng, r As Range
'
' INITIALIZATIONS
'
' These are index numbers for the Resource array
'
Const RName = 0
Const TotHours = 1
Const TotPercent = 2
'
' Set the maximum number of resources we'll
' process.
'
Const ResourceLimit = 1000
'
' We are counting on there being no unintended data
' in the spreadsheet.
'
' It won't matter if the cells are empty though. It just
' may take longer to run the macro.
' But if there is data where this macro does not expect it,
' assume unpredictable results.
'
' There are some hardcoded values used.
' This macro just happens to expect the names to be in Column C (or 3).
'
' Get the last row in the spreadsheet:
'
LastRow = Cells.Find(What:="*", _
                After:=Range("C1"), _
                LookAt:=xlPart, _
                LookIn:=xlFormulas, _
                SearchOrder:=xlByRows, _
                SearchDirection:=xlPrevious, _
                MatchCase:=False).Row
'
'  Furthermore, this macro banks on the first actual name to be in C6.
'  so if the last row is row 65, the range we'll work with 
'  will evaluate to "C6:C65"
'
FirstRow = 6
Rng = "C" & FirstRow & ":C" & LastRow
Set r = Range(Rng)
'
' Initialize the resource array to be empty (even though we don't really
' need to but I'm old school).  
'

    Resource(CurResource, TotHours) = 0
    Resource(CurResource, TotPercent) = 0
Next CurResource
'
' Start the resource counter at 0.  The counter will represent the number of
' unique entries. 
'

'
' LET'S GO
'

' to process all the cells in the spreadsheet we are interested in

'
' Loop here for all unique entries. For any

' initialized in the second if statement.
'
    IsUnique = True
    For j = 1 To nUnique
'
' If the current row element has a resource name and is already
' in the resource array, then accumulate the totals for that
' Resource Name. We then have to set IsUnique to false and
' exit the for loop to make sure we don't populate
' a new array element in the next if statement.
'
        If r.Cells(i, 1).Value = Resource(j, RName) Then
            IsUnique = False

'
' If the resource name is unique then copy the initial
' values we find into the next resource array element.
' I ignore any null cells.   (If the cell has a blank you might
' want to add a Trim to the cell).   Not much error checking for 
' the numerical values either.
'
    If ((IsUnique) And (r.Cells(i, 1).Value <> "")) Then
        nUnique = nUnique + 1
        Resource(nUnique, RName) = r.Cells(i, 1).Value

    End If

' Done processing all rows
'
' (For readability) Set the last resource counter to the last value of
' nUnique.
' Set the current row to the first relative row in the range (r=the range).
'

'
' Populate the destination cells with the accumulated values for
' each unique resource name.
'
For CurResource = 1 To LastResource

    r.Cells(CurrentRow, 8).Value = Resource(CurResource, TotHours)
    r.Cells(CurrentRow, 9).Value = Resource(CurResource, TotPercent)

Next CurResource

Answer 9

还有一种方式......

Sub get_unique()
Dim unique_string As String
    lr = Sheets("data").Cells(Sheets("data").Rows.Count, 1).End(xlUp).Row
    Set range1 = Sheets("data").Range("A2:A" & lr)
    For Each cel In range1
       If Not InStr(output, cel.Value) > 0 Then
           unique_string = unique_string & cel.Value & ","
       End If
    Next
End Sub

Answer 10

下面的VBA脚本从单元格B5一直搜索到列B中的最后一个单元格……$ B $ 1048576。一旦找到，它们就会存储在数组（objDict）中。

Private Const SHT_MASTER = “MASTER”
Private Const SHT_INST_INDEX = “InstrumentIndex”

Sub UniqueList()
    Dim Xyber
    Dim objDict As Object
    Dim lngRow As Long

    Sheets(SHT_MASTER).Activate
    Xyber = Application.Transpose(Sheets(SHT_MASTER).Range([b5], Cells(Rows.count, “B”).End(xlUp)))
    Sheets(SHT_INST_INDEX).Activate
    Set objDict = CreateObject(“Scripting.Dictionary”)
    For lngRow = 1 To UBound(Xyber, 1)
    If Len(Xyber(lngRow)) > 0 Then objDict(Xyber(lngRow)) = 1
    Next
    Sheets(SHT_INST_INDEX).Range(“B1:B” & objDict.count) = Application.Transpose(objDict.keys)
End Sub

Answer 11

如果您不介意使用Variant数据类型，则可以使用内置工作表函数 Unique ，如图所示。

 UPDATE accounts_receivables SET balance = 
      ICASE (
       invoice_no = 3, 6,
       invoice_no = 4, 8,
       "balance" 
            )
      WHERE invoice_no IN (3,4)
