如下代码演示如何创建新的索引。索引针对表的两个列建立。
Sub CreateIndex()
Dim tbl As New Table
Dim idx As New ADOX.Index
Dim cat As New ADOX.Catalog
' 打开目录。
' 打开目录。
cat.ActiveConnection = _
"Provider=Microsoft.Jet.OLEDB.4.0;" & _
"Data Source=c:\Program Files\Microsoft Office\" & _
"Office\Samples\Northwind.mdb;"
' 定义表并将其追加到目录
tbl.Name = "MyTable"
tbl.Columns.Append "Column1", adInteger
tbl.Columns.Append "Column2", adInteger
tbl.Columns.Append "Column3", adVarWChar, 50
cat.Tables.Append tbl
' 定义多列索引
idx.Name = "multicolidx"
idx.Columns.Append "Column1"
idx.Columns.Append "Column2"
' 将索引追加到表上
tbl.Indexes.Append idx
End Sub
