Executing a query from visual basic via an ADO connection to MS Access' linked tables causes an error:

"Data provider failed while executing a provider command"

Windows 2000
Access 2002 developer
Microsoft Data Access Components

How to repeat:
Create an MS Access 2002 database.
Add a linked table to a MySQL table.
Add some code:


Dim myconn as ADODB.connection, myset as ADODB.recordset, sqlstr as string

Set myconn = New ADODB.connection

With myconn
 .ConnectionString = CurrentProject.AccessConnection
 .CursorLocation = adUseClient ' I've tried adUseServer as well
End With

Set myset = New ADODB.Recordset

With myset
 .ActiveConnection = myconn
 .LockType = adLockReadOnly
End With

myset.Open "select * from some_linked_table"


Run the code. The last line will throw an error.

This problem *only* exists when connecting via ADO to MS Access linked tables. If I use an ADO connection to MySQL directly, it works fine. Also, the above approach works with MyODBC-3.51.09.

I wasn't able for to repeat this issue with MS Access 2003 and
3.51.09/10-2 but instead I got different error message like
the connection can't be realized in this context. What it is
the MDAC version on your machine ?

We're using MDAC-2.8.
