Hey Sheeri. Thanks again for the response. I do agree that this is a known problem with SQL Server. My problem is that I am using a Windows Visual Basic application to access a Linux based MySQL Server via MyODBC/Connector. There is no longer SQL Server in the loop. I believe this is a Microsoft Cursor Engine error that is being issued, and it just happens to be the same one that is associated with the SQL Server issue.
I have been able to reproduce my problem on many levels. I created 2 basic tables, created a view where "table1 left join table2". If, in Visual Basic, I call the view and order by a table1 field, I can update. If I order by a table2 field, I can no longer update and get the "Invalid Key Column for Updating or Refreshing" error. While the issue stems from the view definition in MySQL, the actual problem could be caused by Visual Basic, MyODBC or MySQL itself. I don't know what to try next. As always, any help is greatly appreciated. Thanks again, Travis Eland -----Original Message----- From: sheeri kritzer [mailto:[EMAIL PROTECTED] Sent: Fri 5/12/2006 10:01 AM To: Eland, Travis M.
