Excel VBA / SQL联盟

我想join2个不同的工作表的2个独立的列，以使我可以使用Vlookup从更长的列。

Sheet1 A，B，C，D，E，F，G

Sheet2 A，B，C，D，E，F，G

我想将sheet1中的（联合）列B和sheet2中的C连接起来，find新列表的不同值。 我一直在为此工作数周。

谢谢

您可以使用Excel的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, BC 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.
