我有一个崩溃我的Excel的代码,它从一张纸上获取数据并将其从表格视图转换为垂直。我认为它很慢,因为它从数据库视图中获取超过45k行。
有没有人有任何优化此代码的提示?在next c
循环
此外,我尝试在excel 2010中运行此操作,得到overflow
错误,但通常2010年运行得更好,2013年速度缓慢或无响应。但是我想让它在2013年工作。

答案 0 :(得分:7)
对不起,但我不想分析您的代码,甚至出于某些原因也不想使用它...
首先,VBA编程中的一个常见错误是使用了未指定(未声明)的变量。这会导致多个问题,尤其是在程序员犯了拼写错误(键入错误)时,例如,他使用myvariable
代替了myvairable
。所以...
强烈建议使用Option Explicit statement,因为...如MSDN文档所述:
如果您未指定数据类型,则会分配
Variant
数据类型 默认情况下。(...)
Variant
类型的变量比大多数其他变量需要更多的内存资源(...)
如果模块包含
Option Explicit
语句,则会发生编译时错误 当Visual Basic遇到以前未声明的变量名时, 或拼写错误。
有关更多详细信息,请参见:
Wikipedia: Visual Basic for Applications
VBA: Declaring Variables
Runtime vs Compile time
Office Talk: Working with VBA in the 32-bit and 64-bit Versions of Office 2010
所有的第二个,当您尝试进行超出分配目标限制的分配时,会发生Overflow错误。该错误可能是Excel崩溃的原因。
第三个,您应该在上下文中使用代码。代码的非上下文使用可能是几个问题的原因,例如数据丢失。
想象一下:有2个打开的工作簿。他们两个都有相同的工作表集:Sheet1
,Sheet2
和Sheet3
。当您使用Sheets("Sheet1").Range("A1") = "whatever"
时,在活动工作簿中进行了更改,例如Workbook1
,但是您想在Workbook2
中进行更改。知道了吗?
顺便说一句:请注意,Sheet
与Worksheet
不同
Sheets与Worksheets
因此,使用上下文代码的正确方法是:
Dim srcWsh As Worksheet
Dim trgWsh As Worksheet
Set srcWsh = ThisWorkbook.Worksheets("Sheet1") 'you can use index too, see:
Set trgWsh = Workbooks("Workbook2").Worksheets(2)
trgWsh.Range("A1") = srcWsh.Range("A1")
'finally, you have to clean up
Set srcWsh = Nothing
Set trgWsh = Nothing
时必须使用相同的规则

关于反转(取消透视)数据的方法...
我确实使用了MSDN的示例:Using PIVOT and UNPIVOT,其中这些数据:
VendorID Emp1 Emp2 Emp3 Emp4 Emp5
1 4 3 5 4 4
2 4 1 5 5 5
3 4 3 5 4 4
4 4 2 5 5 4
5 5 1 5 5 5
必须“转换”为以下形式:
VendorID Employee Orders
----------- ----------- ------
1 Emp1 4
1 Emp2 3
1 Emp3 5
1 Emp4 4
1 Emp5 4
2 Emp1 4
2 Emp2 1
2 Emp3 5
2 Emp4 5
2 Emp5 5
...
我的代码:
Option Explicit
Sub Test()
UnpivotData ThisWorkbook.Worksheets("Arkusz1"), _
ThisWorkbook.Worksheets("Arkusz2"), _
"A1", "B1:F1"
End Sub
Sub UnpivotData(ByVal srcWsh As Worksheet, ByVal trgWsh As Worksheet, ByVal unpvtFor As String, ByVal pivotedColumns As String, _
Optional ByVal commonHeader As String = "Employee", Optional ByVal pvtValuesToCol As String = "Orders")
'declare variables
Dim lastrow As Long, r As Long, trgr As Long
Dim c As Long, cName As String
'on error go to error handler
On Error GoTo Err_UnpivotData
'find last row
lastrow = srcWsh.UsedRange.Rows.Count
'context!
With trgWsh
'clear
.Cells.Clear
'add headers
.Range("A1") = srcWsh.Range(unpvtFor)
.Range("B1") = commonHeader
.Range("C1") = pvtValuesToCol
'"convert" values
r = 1
trgr = 0
'loop through the collection of rows in srcWsh
Do While r < lastrow
'loop through the collection of pivoted columns in srcWsh
For c = 0 To srcWsh.Range(pivotedColumns).Columns.Count - 1
'unpivot value of 1. column
.Range("A2").Offset(RowOffset:=trgr, ColumnOffset:=0) = srcWsh.Range(unpvtFor).Offset(RowOffset:=r, ColumnOffset:=0)
'unpivot header
cName = srcWsh.Range(pivotedColumns).Columns(c + 1).Address
.Range("A2").Offset(RowOffset:=trgr, ColumnOffset:=1) = srcWsh.Range(cName).Rows(1)
'unpivot value
.Range("A2").Offset(RowOffset:=trgr, ColumnOffset:=2) = srcWsh.Range(unpvtFor).Offset(RowOffset:=r, ColumnOffset:=c + 1)
'increase target counter
trgr = trgr + 1
Next
'increase source counter
r = r + 1
Loop
End With
Exit_UnpivotData:
On Error Resume Next
'clean up
Exit Sub
Err_UnpivotData:
MsgBox Err.Description, vbExclamation, Err.Number
Resume Exit_UnpivotData
End Sub
随时根据您的需要进行更改...

我希望我已经详细解释了您的代码出了什么问题。
[EDIT]

答案 1 :(得分:0)
尝试一下:
