如下代碼演示如何創建新的索引。索引針對表的兩個列建立。</p>
<pre>Sub CreateIndex() Dim tbl As New Table
Dim idx As New ADOX.Index
Dim cat As New ADOX.Catalog' 打開目錄。
' 打開目錄。
cat.ActiveConnection = _
"Provider=Microsoft.Jet.OLEDB.4.0;" & _
"Data Source=c:\Program Files\Microsoft Office\" & _
"Office\Samples\Northwind.mdb;" ' 定義表并將其追加到目錄
tbl.Name = "MyTable"
tbl.Columns.Append "Column1", adInteger
tbl.Columns.Append "Column2", adInteger
tbl.Columns.Append "Column3", adVarWChar, 50
cat.Tables.Append tbl ' 定義多列索引
idx.Name = "multicolidx"
idx.Columns.Append "Column1"
idx.Columns.Append "Column2" ' 將索引追加到表上
tbl.Indexes.Append idxEnd Sub
