You can merge the results of two or more queries, tables, and SELECT statements in a single UNION operation. The following example demonstrates how you can use the UNION operation to append two tables:

 Sub AppendTables()
 
 Dim db As Database
 Dim Results As Recordset
 Dim i As Integer
 
   'Open the dBASE IV database
   Set db = OpenDatabase("c:\my documents", False, False, "dBASE IV;")
 
   'Create a recordset that is a union of the January table
   'and the February Table
   Set Results = _
 
      db.OpenRecordset("Select * from January" & _
        "UNION Select * from February")
 
   'Return the column headers to the first row of Sheet1
 
    For i = 0 To Results.Fields.Count - 1
      Sheets("Sheet1").Range("A1").Offset(, i) = Results.Fields(i).Name
    Next
 
   'Return the recordset results to Sheet1
   Sheets("Sheet1").Range("a2").CopyFromRecordset Results
 
   db.Close
 
 End Sub
				

If the January and February tables used in the AppendTables macro appear as in the following tables

   January.DBF                         February.DBF
   ------------------------            ------------------------
   DATE      QTY     AMOUNT            DATE      QTY     AMOUNT
   1/3/95     1      66.99             2/6/95     6      44.91
   1/5/95     6      59.11             2/9/95     7      19.13
   1/8/95     4       2.80             2/10/95    2      20.56
   1/8/95     3      11.12             2/10/95    3      69.94
   1/9/95     2      49.71             2/11/95    8      71.67
   1/15/95    3      59.76             2/19/95    1      93.61
   1/23/95    7      93.32             2/24/95    4      57.76
   1/23/95    8      90.96             2/26/95    3      98.13
				

the results returned to Sheet1 using the macro are as follows

   DATE      QTY     AMOUNT
   1/3/95     1      66.99
   1/5/95     6      59.11
   1/8/95     4       2.80
   1/8/95     3      11.12
   1/9/95     2      49.71
   1/15/95    3      59.76
   1/23/95    7      93.32
   1/23/95    8      90.96
   2/6/95     6      44.91
   2/9/95     7      19.13

   2/26/95    3      98.13
				

To use the Data Access Object commands in a Microsoft Excel Visual Basic for Applications macro, the DAO library must be referenced. To reference the DAO library use the following steps:

1. Activate the module sheet containing the macro.
2. On the Tools menu, click References.
3. In Microsoft Excel 97, select the Microsoft DAO 3.5 Object Library check box or in Microsoft Excel version 7.0, select the Microsoft DAO 3.0 Object Library check box, and then click OK.
