BUG: Problem Updating ADO Hierarchical Recordset When Join Tables Share Same Column Name

When updating an ActiveX Data Objects (ADO) recordset, an error occurs if the recordset, based on a SHAPE command, joins two tables where the primary key of one table has the same name as a column name of the other table. The following error appears: The preceding error occurs when you connect to Oracle through Microsoft ODBC for Oracle.

Microsoft has confirmed this to be a bug in the Microsoft products listed at the beginning of this article.

Steps to Reproduce Behavior

1. Start a new project in Visual Basic and choose Standard EXE. Form1 is created by default.
2. In the Visual Basic project, add a reference to the the Microsoft ActiveX Data Objects Library.
3. Double-click Form1. Copy and paste the following code into the Form_Load() event:

       Dim Sql As String
       Dim cn As New ADODB.Connection
       Dim rs As New ADODB.Recordset
       
       cn.Open "Provider=MSDataShape.1;Data Provider=MSDASQL;Driver={Microsoft ODBC for Oracle};UID=xxx;PWD=xxx;Server=MyServer;"
     
       On Error Resume Next
       cn.Execute "Drop Table A"
       cn.Execute "Drop Table B"
       On Error GoTo 0
       cn.Execute "Create Table A (APkID Number PRIMARY KEY, BPkID Number)"
       cn.Execute "Create Table B (BPkID Number PRIMARY KEY, BColumn Varchar2(5))"
       cn.Execute "Insert Into A (APkID) Values(1)"
       cn.Execute "Insert Into B (BPkID, BColumn) Values(1,'Mary')"
       
       Sql = "Shape {Select A.APkID, B.BPkID, B.BColumn From A,B Where A.APkID = B.bPkID}" & _
             " Append Calc(1) as Chapter"
       rs.Open Sql, cn, adOpenKeyset, adLockBatchOptimistic
       rs.Fields("BColumn").Value = "Test"
       rs.UpdateBatch  'Error occurs here
       rs.Close
       cn.Close
