Visual Basic Code Example

1. Insert a Visual Basic module into a new Microsoft Excel workbook.

2. Create a reference to the Microsoft DAO object library. In Microsoft 

   Excel 97 the DAO library will be version 3.5. In Microsoft Excel 7.0
   the DAO library will be version 3.0.
3. Type the following code into the module sheet: 

   ' This code assumes you have Microsoft Access 7.0 installed and have
   ' the Northwind.mdb sample database installed in the default
   ' location.

   Sub CreateRecordSet()

     Dim oldDbName As String
     Dim wspDefault As Workspace
     Dim dbsNorthwind As Database
     Dim strSQL As String
     Dim rstFromQuery As Recordset

     'Set the path to the database
     oldDbName = "C:\Msoffice\access\samples\Northwind.mdb"

     'Create a default workspace Object
     Set wspDefault = DBEngine.Workspaces(0)

     'Create a Database object
     Set dbsNorthwind = wspDefault.OpenDatabase(oldDbName)

     'The SQL statement
     strSQL = "SELECT Employees.LastName, Employees.FirstName, " & _
        "Employees.Country FROM Employees Employees " & _
        "WHERE (Employees.Country='USA')"

     'Create a Snapshot Type Recordset from the SQL query
     Set _
     rstFromQuery = dbsNorthwind.OpenRecordset(strSQL,dbOpenSnapshot)

     'Show the number of fields returned
     MsgBox "there are " & rstFromQuery.Fields.Count & _
     " fields that were returned"

     'Move to the last record in the recordset
     rstFromQuery.MoveLast

     'Show the number of records returned
     MsgBox "there are " & rstFromQuery.RecordCount & _
     " records that were returned"

  End Sub
