Question

我正在使用MS Access数据库并尝试从C＃2.0获取完整数据。如何使用ADOX获取constriant名称（例如：Primarykey的名称而不是主键的字段名称）。

提前致谢马杜

SQL = "CREATE TABLE PKTEST1 (f1 INT PRIMARY KEY, f2 INT)"
cn.Execute SQL

Set cat.ActiveConnection = cn

'Check all indexes on the table for a primary key'
For Each idx In cat.Tables("PKTEST1").Indexes
        If idx.PrimaryKey = True Then
        Debug.Print "INDEX  NAME: " & idx.Name

        'Show all columns that make up the index'
        Debug.Print "consists of the following columns:"
        For i = 0 To idx.Columns.Count - 1
            Debug.Print idx.Columns(i).Name
        Next

    End If
