在此代码中查看包含来自不同系统的类似数据的2个工作表。第1列包含一个唯一的工作人员编号,因此可以匹配该人员,然后在工作表之间存在NiNo ws1.cell(,17) and ws2.cell(,24)
的差异,然后将该人员的某些值复制到第3张工作表。
然而,有18种不同的工作表都在考虑不同的标准,因此这段代码必须运行18次并且需要一段时间。任何想法我如何加快它的例子请
Sub NINODifferences()
Application.ScreenUpdating = False
Application.Calculation = xlCalculationManual
Dim ws1 As Worksheet, ws2 As Worksheet, ws3 As Worksheet, ws4 As Worksheet
Dim i As Long, j As Long, iCol As Long, iRow As Long
Set ws1 = ActiveWorkbook.Sheets("SheetA")
Set ws2 = ActiveWorkbook.Sheets("SheetB")
Set ws3 = ActiveWorkbook.Sheets("NINO Differences")
iRow = 2
iCol = 1
For i = 1 To ws1.Cells(ws1.Rows.Count, 1).End(xlUp).Row
For j = 1 To ws2.Cells(ws2.Rows.Count, 1).End(xlUp).Row
If Trim(ws1.Cells(i, 1).Value2) = Trim(ws2.Cells(j, 1).Value2) Then
If Trim(ws1.Cells(i, 17).Value2) <> Trim(ws2.Cells(j, 24).Value2) Then
ws3.Cells(iRow, iCol).Value2 = ws1.Cells(i, 1).Value2
iCol = iCol + 1
ws3.Cells(iRow, iCol).Value2 = ws1.Cells(i, 2).Value2
iCol = iCol + 1
ws3.Cells(iRow, iCol).Value2 = ws1.Cells(i, 3).Value2
iCol = iCol + 1
ws3.Cells(iRow, iCol).Value2 = ws1.Cells(i, 17).Value2
iCol = iCol + 1
ws3.Cells(iRow, iCol).Value2 = ws2.Cells(j, 24).Value2
iCol = 1
iRow = iRow + 1
Else
End If
Else
End If
Next j
Next i
Set ws1 = Nothing
Set ws2 = Nothing
Set ws3 = Nothing
End Sub
尝试重写您的代码(这将是一项艰巨的工作),尝试执行以下操作:
Sub TestMe()
Dim firstArr As Variant
Dim secondArr As Variant
Dim cnt As Long
firstArr = Application.Transpose(Range("A1:A20"))
secondArr = Application.Transpose(Range("B1:B20"))
'Read the corresponding cells and save them to an array
'Here instead of reading I am generating them
For cnt = LBound(firstArr) To UBound(firstArr)
firstArr(cnt) = cnt
secondArr(cnt) = cnt * 3
Cells(cnt, 1) = firstArr(cnt)
Cells(cnt, 2) = secondArr(cnt)
Next cnt
'Make all the calculations until you receive an array with the results
For cnt = LBound(firstArr) To UBound(secondArr)
firstArr(cnt) = firstArr(cnt) + secondArr(cnt)
Next cnt
'Write this array to the worksheet
For cnt = LBound(firstArr) To UBound(secondArr)
Cells(cnt, 3) = firstArr(cnt)
Next cnt
End Sub
如果你设法做到这一点,表现奖金会很明显。作为一个小的(不需要的)建议 - 不要使用这一行,有些人认为这是一个坏习惯:
Application.Calculation = xlCalculationManual
根据Vityata所讨论的精神(重写代码以使用数组)而不完全确定您的数据是什么样的,您可以使用以下内容:
Sub NINODifferences()
Dim ws1 As Variant, ws2 As Variant, ws3 As Variant
Dim i As Long, j As Long
ws1 = ActiveWorkbook.Sheets("SheetA").UsedRange
ws2 = ActiveWorkbook.Sheets("SheetB").UsedRange
ReDim ws3(4, 0)
For i = 1 To UBound(ws1)
For j = 1 To UBound(ws2)
If Trim(ws1(i, 1)) = Trim(ws2(j, 1)) Then
If Trim(ws1(i, 17)) <> Trim(ws2(j, 24)) Then
ReDim Preserve ws3(4, count)
ws3(0, count) = ws1(i, 1)
ws3(1, count) = ws1(i, 2)
ws3(2, count) = ws1(i, 3)
ws3(3, count) = ws1(i, 17)
ws3(4, count) = ws2(i, 24)
count = count + 1
End If
End If
Next j
Next i
Call PasteArray(transposeArray(ws3), ActiveWorkbook.Sheets("NINO Differences").[A1])
Set ws1 = Nothing
Set ws2 = Nothing
End Sub
Sub PasteArray(data As Variant, rng As Range)
rng.Resize(UBound(data, 1) + 1, UBound(data, 2) + 1) = data
End Sub
Function transposeArray(data)
If IsEmpty(data) Then Exit Function
ReDim r(UBound(data, 2), UBound(data))
For i = LBound(r) To UBound(r)
For j = LBound(r, 2) To UBound(r, 2)
r(i, j) = data(j, i)
Next j
Next i
transposeArray = r
End Function
