Excel VBA/SQL Union

Question

Я пытаюсь присоединиться к 2 отдельным столбцам из двух разных листов, чтобы создать более длинный столбец, из которого я могу использовать Vlookup.

Лист1 A, B, C, D, E, F, G

Sheet2 A, B, C, D, E, F, G

Я хочу присоединиться (союз) Колонны B от листа 1 и C от листа 2 вместе и найти отличительные значения нового списка. Я работаю над этим несколько недель.

Thanks

Вы можете использовать ADO с Excel.

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
