ODBCDirect workspaces are not supported in Microsoft Office Access 2007. Use ADO if you want to access external data sources without using the Microsoft Access database engine.
Returns the Database object that corresponds to this connection (ODBCDirect workspaces only).
Syntax
expression.Database
expression A variable that represents a Connection object.
Remarks
On a Connection object, use the Database property to obtain a reference to a Database object that corresponds to the Connection. In DAO, a Connection object and its corresponding Database object are simply two different object variable references to the same object. The Database property of a Connection object and the Connection property of a Database object make it easier to change connections to an ODBC data source through the Microsoft Access database engine to use ODBCDirect.
Example
This example uses the Database property to show how code that used to access ODBC data through the Microsoft Access database engine can be converted to use ODBCDirect Connection objects.
The OldDatabaseCode procedure uses a Microsoft Access database engine-connected data source to access an ODBC database.
Visual Basic for Applications
Sub OldDatabaseCode()
Dim wrkMain As Workspace
Dim dbsPubs As Database
Dim prpLoop As Property
' Create a Workspace object.
Set wrkMain = CreateWorkspace("", "admin", "", dbUseJet)
' Open a Database object based on information in
' the connect string.
'Note: The DSN referenced below must be configured to
' use Microsoft Windows NT Authentication Mode to
' authorize user access to the Microsoft SQL Server.
Set dbsPubs = wrkMain.OpenDatabase("Publishers", _
dbDriverNoPrompt, False, _
"ODBC;DATABASE=pubs;DSN=Publishers")
' Enumerate the Properties collection of the Database
' object.
With dbsPubs
Debug.Print "Database properties for " & _
.Name & ":"
On Error Resume Next
For Each prpLoop In .Properties
If prpLoop.Name = "Connection" Then
' Property actually returns a Connection object.
Debug.Print " Connection[.Name] = " & _
.Connection.Name
Else
Debug.Print " " & prpLoop.Name & " = " & _
prpLoop
End If
Next prpLoop
On Error GoTo 0
End With
dbsPubs.Close
wrkMain.Close
End Sub
The NewDatabaseCode example opens a Connection object in an ODBCDirect workspace. It then assigns the Database property of the Connection object to an object variable with the same name as the data source in the old procedure. None of the subsequent code has to be changed as long as it doesn't use any features specific to Microsoft Access workspaces.
Visual Basic for Applications
Sub NewDatabaseCode()
Dim wrkMain As Workspace
Dim conPubs As Connection
Dim dbsPubs As Database
Dim prpLoop As Property
' Create ODBCDirect Workspace object instead of Microsoft
' Access Workspace object.
Set wrkMain = CreateWorkspace("", "admin", "", dbUseODBC)
' Open Connection object based on information in
' the connect string.
' Note: The DSN referenced below must be configured to
' use Microsoft Windows NT Authentication Mode to
' authorize user access to the Microsoft SQL Server.
Set conPubs = wrkMain.OpenConnection("Publishers", _
dbDriverNoPrompt, False, _
"ODBC;DATABASE=pubs;DSN=Publishers")
' Assign the Database property to the same object
' variable as in the old code.
Set dbsPubs = conPubs.Database
' Enumerate the Properties collection of the Database
' object. From this point on, the code is the same as the
' old example.
With dbsPubs
Debug.Print "Database properties for " & _
.Name & ":"
On Error Resume Next
For Each prpLoop In .Properties
If prpLoop.Name = "Connection" Then
' Property actually returns a Connection object.
Debug.Print " Connection[.Name] = " & _
.Connection.Name
Else
Debug.Print " " & prpLoop.Name & " = " & _
prpLoop
End If
Next prpLoop
