Indexes Append Method Example (VB)

The following code demonstrates how to create a new index. The index is on two columns in the table.

' BeginCreateIndexVB
Sub Main()
    On Error GoTo CreateIndexError

    Dim tbl As New Table
    Dim idx As New ADOX.Index
    Dim cat As New ADOX.Catalog
    
    'Open the catalog.
    ' Open the Catalog.
    cat.ActiveConnection = "Provider='Microsoft.Jet.OLEDB.4.0';" & _
        "Data Source='c:\Program Files\Microsoft Office\" & _
        "Office\Samples\Northwind.mdb';"
    
    ' Define the table and append it to the catalog
    tbl.Name = "MyTable"
    tbl.Columns.Append "Column1", adInteger
    tbl.Columns.Append "Column2", adInteger
    tbl.Columns.Append "Column3", adVarWChar, 50
    cat.Tables.Append tbl
    Debug.Print "Table 'MyTable' is added."
    
    ' Define a multi-column index
    idx.Name = "multicolidx"
    idx.Columns.Append "Column1"
    idx.Columns.Append "Column2"
    
    ' Append the index to the table
    tbl.Indexes.Append idx
    Debug.Print "The index is appended to table 'MyTable'."
    
    'Delete the table as this is a demonstration
    cat.Tables.Delete tbl.Name
    Debug.Print "Table 'MyTable' is deleted."
    
    'Clean up
    Set cat.ActiveConnection = Nothing
    Set cat = Nothing
    Set tbl = Nothing
    Set idx = Nothing
    Exit Sub
    
CreateIndexError:
    Set cat = Nothing
    Set tbl = Nothing
    Set idx = Nothing
    
    If Err <> 0 Then
        MsgBox Err.Source & "-->" & Err.Description, , "Error"
    End If
End Sub
' EndCreateIndexVB
