Multi -Column Primary Key

As we know, the statement "Set rsPrimaryKeys = cn.OpenSchema(adSchemaPrimaryKeys)" retrives primary key columns defined in the catalog.

Here is my question:

For each of these tables, the primary key maybe consists of more than one column. How to tell the primary key is consist of a single column or multi-column?

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

To check whether the primary key consists of one or more column try the following code:

Set rs = cnn.OpenSchema(adSchemaPrimaryKeys)
Do Until rs.EOF
    If rs!TABLE_NAME = "Table_name" Then
      MsgBox rs.Fields("Column_Name") & "   " & rs.Fields("PK_Name")
    End If
