嗨伙伴们,VBA宏崩溃Excel

我正在运行一个宏来删除包含特定值的整个行。该代码在小数据集上工作正常,但在当前版本(约22,000条记录)上,它一直崩溃Excel(2010)。代码如下。在将数据拆分成更小的块并一次又一次地运行宏之后,我不知道该怎么做。

赞赏任何帮助和下面的代码:

Sub CleanOcc() 

'Row counting 
Dim Firstrow As Long 
Dim Lastrow As Long 
Dim Lrow As Long 
Dim Lrow2 As Long 

With Sheets("Occ_Prep") 

    'Cleans the occ_prep sheet ready for upload (Column and value can be changed) 
    Sheets("Occ_Prep").Activate 

    'Set the first and last row to loop through 
    Firstrow = .UsedRange.Cells(1).Row 
    Lastrow = .UsedRange.Rows(.UsedRange.Rows.Count).Row 

    'We loop from Lastrow to Firstrow (bottom to top) 
    For Lrow2 = Lastrow To Firstrow Step -1 

     'We check the values in the A column in this example 
     With .Cells(Lrow2, "K") 


      If Not IsError(.Value) Then 

       If .Value = "0" Then .EntireRow.Delete 
       'This will delete each row with the Value "ron" 
       'in Column A, case sensitive. 

      End If 

     End With 

    Next Lrow2 

End With 



End Sub

Excel和真正大量的数据不会混合,它不是真的意味着数据库:\ – 2013-05-01 21:21:12

这是找到最后一个单元格的一种非常错误的方法。请参见[THIS](http://stackoverflow.com/questions/11169445/error-finding-last-used-cell-in-vba)另请参阅[THIS](http://social.msdn.microsoft.com/Forums/en-US/exceldev/thread/da7d1600-43bc-4e04-b2cc-8c4871349964)这里我使用'delrange'对象来删除相关的行。只需修改它以适应您的需求。 – 2013-05-01 21:41:00

另一种方式。使用自动过滤器在'0'上过滤Col K,然后删除相关的行。参见[THIS](http://stackoverflow.com/questions/11631363/how-to-copy-a-line-in-excel-using-a-specific-word-and-pasting-to-another-excel-s )这显示了如何使用过滤的范围。只需修改它即可删除您的范围 – 2013-05-01 21:43:41

同意亚洲时报Siddharth评论自动筛选的路要走。这应该快很多。

Option Explicit 
Sub delrows() 
    Dim ws As Worksheet 
    Dim LR As Long 
    Dim rng As Range, frng As Range 

    Application.ScreenUpdating = False 

    Set ws = Sheets("dataset") '<-- Change this to name of your worksheet 
    With ws 
     LR = .Range("A" & Rows.Count).End(xlUp).Row 
     .AutoFilterMode = False 
     Set rng = .Range("A1:C" & LR) '<-- Assuming K is the last column 
     rng.AutoFilter 3, "0" '<-- 11 referes to Column K 
     Set frng = rng.Offset(1, 0).SpecialCells(xlCellTypeVisible) '<-- Don't delete the header 
     frng.EntireRow.Delete 
     .AutoFilterMode = False 
    End With 

    Application.ScreenUpdating = True 
End Sub 

编辑:我刚在〜5秒钟内清理了20000行(3列)的数据。显然这取决于有多少比赛。
