如何从 MS access 2007 中的特定表中选择索引

Question

我想选择索引列表并将其放入 viusal basic 的数据表中，并且 iam 使用 oledb 连接到 2002-2003 数据库格式 (.mdb)

喜欢，

Dim con as new oledb.oledbconnection 
Dim conAdapter as oledb.oledbDataAdabter
Dim Table as new datatable

conn.ConnectionString = "Provider=Microsoft.jet.OLEDB.4.0; Data Source='MY DATABESE LOCATION';"
conn = New OleDb.OleDbDataAdapter("SELECT * FROM 'what i want to select table1 indexes'", conn)
connAdabter.fill(Table)

谢谢

OleDbConnection 有一个方法可以返回有关表、索引等的 SCHEMA 信息...

 Dim connectionString = "Provider=Microsoft.jet.OLEDB.4.0; Data Source='MY DATABESE LOCATION';"
 Using con as new oledb.oledbconnection(connectionString)
    con.Open()
    Dim indexes = con.GetSchema("Indexes").Select("TABLE_NAME = 'yourTableNameHere'").CopyToDataTable()
    For Each row in indexes.Rows
        Console.WriteLine(row("INDEX_NAME"))
        Console.WriteLine(row("COLUMN_NAME"))
        Console.WriteLine(row("PRIMARY_KEY"))
    Next

End Using
