在Excel中使用VBA组合两个表

本文介绍了在Excel中使用VBA组合两个表的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

使用Excel VBA我希望能够将Excel中的两个表与一个公共密钥相结合。我建议ADODB作为一种方法，但可以使用任何其他更有效/优雅的方法。请参阅下面的一个最小的例子：

Using Excel VBA I would like to be able to combine two tables in excel with a common key. I have suggested ADODB as a method,but am open to any other more efficient/elegant methods. Please see below for a minimal example:

我有以下开始...

Sheet1

A B C 1 type year1 year2 2 aaa 100 110 3 bbb 220 240 4 ccc 304 200 5 ddd 20 30 6 eee 440 20

Sheet2

A B C 1 type year1 year2 2 bbb 10 76 3 ccc 44 39 4 ddd 50 29 5 eee 22 23 6 fff 45 55

并且想结合它，所以我有以下结果：

And would like to combine it so that I have the following as a result:

Sheet3

A B C D E 1 type year1 year2 year1 year2 2 aaa 100 110 0 0 3 bbb 220 240 10 76 4 ccc 304 200 44 39 5 ddd 20 30 50 29 6 eee 440 20 22 23 7 fff 0 0 45 55

做了一些谷歌搜索和SQL类型的外连接似乎很接近但不

Have done a bit of googling and SQL type outer joins seems close but not sure how to implement it.

以下是到目前为止试用和实现的代码...

Below is the code used to try and implement it so far...

Option Explicit Sub JoinTables() Dim cn As ADODB.Connection Set cn = New ADODB.Connection With cn .Provider = "Microsoft.Jet.OLEDB.4.0" .ConnectionString = "Data Source=" & ThisWorkbook.FullName & ";" & _ "Extended Properties=Excel 8.0;" .Open End With Dim rs As ADODB.Recordset Set rs = New ADODB.Recordset rs.Open "SELECT * FROM [Sheet1$] OUTER JOIN [Sheet2$] ON [Sheet1$].[type] = " & _ "[Sheet2$].[type]", cn With Worksheets("Sheet3") .Cells(2, 1).CopyFromRecordset rs End With rs.Close cn.Close End Sub

推荐答案

根据你是否在任何一张表上都有重复的值，我可以想到一些想法，而不是使用SQL。

Depending on whether or not you have duplicate values on either sheet, I could think of a few ideas, not using SQL though.

• 获取SourceSheet1和SourceSheet2 - 将它们设置为lastRow1& lastRow2
• 为每个工作表创建行代码。 s1Row，s2Row，tRow
• set tRow = 2对于TargetSheet的第一行
• 使用For循环遍历SourceSheet1的每一行。使用这样的东西
• 当代码的第一部分循环完成后，您将完成将SourceSheet1中的每个项目添加到TargetSheet上。那么你必须检查SourceSheet2中的值，看看是否有唯一的列表。
• 完成后，你应该只添加了你初始搜索中缺少的那些。然后targetSheet将按照SourceSheet1所有项目的顺序，然后从SourceSheet2的额外项目

• Get LastRow of SourceSheet1 & SourceSheet2 - Set them as variables lastRow1 & lastRow2
• Create a row ticker for each sheet. s1Row, s2Row, tRow
• set tRow = 2 For the TargetSheet's first line
• Use For loop to cycle through each row of SourceSheet1. Using something like this
• When the first part of code is done looping, you will be finished adding every item from SourceSheet1 onto the TargetSheet. Then you will have to check the values from SourceSheet2 to see if any were unique to that list.
• When that is done, you should have only added the ones that were missing from your initial search. Then the targetSheet will be in the order of SourceSheet1 All Items, then the extra items from SourceSheet2

SET VARIABLES

SET VARIABLES

Private Sub JoinLists() Dim rng As Range Dim typeName As String Dim matchCount As Integer Dim s1Row As Integer Dim s2Row As Integer Dim tRow As Integer Dim m As Integer Dim lastRow1 As Integer Dim lastRow2 As Integer Dim SourceSheet1 As String Dim SourceSheet2 As String Dim TargetSheet As String SourceSheet1 = "Source1" SourceSheet2 = "Source2" TargetSheet = "Target" tRow = 2 lastRow1 = Sheets(SourceSheet1).Range("A65536").End(xlUp).row lastRow2 = Sheets(SourceSheet2).Range("A65536").End(xlUp).row

第一阶段：复制从Sheet1到Target的每个条目，同时从Sheet2抓取匹配

PHASE ONE: Copying every entry from Sheet1 to Target, while grabbing matches from Sheet2

Set rng = Sheets(SourceSheet2).Range("A2:A" & lastRow2) For s1Row = 2 To lastRow1 typeName = Sheets(SourceSheet1).Cells(s1Row, 1) matchCount = Application.WorksheetFunction.CountIf(rng, typeName) 'Set the Row up on the TargetSheet. No matter if it's a match. Sheets(TargetSheet).Cells(tRow, 1) = typeName Sheets(TargetSheet).Cells(tRow, 2) = Sheets(SourceSheet1).Cells(s1Row, 2) Sheets(TargetSheet).Cells(tRow, 3) = Sheets(SourceSheet1).Cells(s1Row, 3) 'Check to see if there are any matches on SourceSheet2 If matchCount = 0 Then 'There are NO matches. Add Zeros to the extra columns Sheets(TargetSheet).Cells(tRow, 4) = 0 Sheets(TargetSheet).Cells(tRow, 5) = 0 Else 'Get first matching occurance on the SourceSheet2 m = Application.WorksheetFunction.Match(typeName, rng, 0) 'Get Absolute Row number of that match s2Row = m + 1 ' This takes into account the Header Row, as index 1 is Row 2 of the search Range 'Set the extra columns on TargetSheet to the Matches on SourceSheet2 Sheets(TargetSheet).Cells(tRow, 4) = Sheets(SourceSheet1).Cells(s2Row, 2) Sheets(TargetSheet).Cells(tRow, 5) = Sheets(SourceSheet1).Cells(s2Row, 3) End If tRow = tRow + 1 Next s1Row

第二步：检查SourceSheet2不在Sheet1上的条目

PHASE TWO: Checking SourceSheet2 for Entries NOT on Sheet1

Set rng = Sheets(SourceSheet1).Range("A2:A" & lastRow1) For s2Row = 2 To lastRow2 typeName = Sheets(SourceSheet2).Cells(s2Row, 1) matchCount = Application.WorksheetFunction.CountIf(rng, typeName) If matchCount = 0 Then 'There are NO matches. Add to Target Sheet Sheets(TargetSheet).Cells(tRow, 1) = typeName Sheets(TargetSheet).Cells(tRow, 2) = 0 Sheets(TargetSheet).Cells(tRow, 3) = 0 Sheets(TargetSheet).Cells(tRow, 4) = Sheets(SourceSheet2).Cells(s2Row, 2) Sheets(TargetSheet).Cells(tRow, 5) = Sheets(SourceSheet2).Cells(s2Row, 3) tRow = tRow + 1 'Not doing anything for the matches, because they were already added. End If Next s2Row End Sub
