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 idxEnd Sub
