Question

我正在尝试从2个不同的工作表中加入2个单独的列来制作更长的列，然后我可以从中使用Vlookup。

Sheet 1中 A，B，C，D，E，F，G

Sheet 2中 A，B，C，D，E，F，G

我想从sheet1加入（联合）列B和从sheet2加入C，并找到新列表的Distinct值。我这个星期一直在研究这个问题。

您可以在Excel中使用ADO。

Dim cn As Object
Dim rs As Object
Dim strFile As String
Dim strCon As String
Dim strSQL As String
Dim s As String
Dim i As Integer, j As Integer

''This is not the best way to refer to the workbook
''you want, but it is very conveient for notes
''It is probably best to use the name of the workbook.

strFile = ActiveWorkbook.FullName

''Note that if HDR=No, F1,F2 etc are used for column names,
''if HDR=Yes, the names in the first row of the range
''can be used. 
''This is the Jet 4 connection string, you can get more
''here : http://www.connectionstrings.com/excel

strCon = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & strFile _
    & ";Extended Properties=""Excel 8.0;HDR=Yes;IMEX=1"";"

''Late binding, so no reference is needed

Set cn = CreateObject("ADODB.Connection")
Set rs = CreateObject("ADODB.Recordset")


cn.Open strCon

''A sample query
strSQL = "SELECT Distinct A, B C FROM ( " _
       & "SELECT A, B, C " _
       & "FROM [Sheet1$] " _
       & "UNION ALL " _
       & "SELECT A, B, C " _
       & "FROM [Sheet2$] ) As J "


''Open the recordset for more processing
''Cursor Type: 3, adOpenStatic
''Lock Type: 3, adLockOptimistic
''Not everything can be done with every cirsor type and 
''lock type. See http://www.w3schools.com/ado/met_rs_open.asp

rs.Open strSQL, cn, 3, 3

''Write out the data to an empty sheet (no headers)
Worksheets("Sheet3").Cells(2, 1).CopyFromRecordset rss
