Excel AddNew QueryTable '1004' problem

H

Holly

Hi guys. I'm a newbie so please forgive this - but I don't know what
else to do. This spreadsheet is from hell.
I have been having such a problem with automating this excel
spreadsheet. The users wanted to update a field in an oracle table
from this spreadsheet. The problem is either with the refresh or the
loop, but it will only (intermittently) update the first record (if I
comment out the refresh background query) and skip the rest, or if I
leave refresh on or set it to false, then it gives me the dreaded
'1004' error.

I know parameter queries are tricky with oracle/microsoft OLE DB for
Oracle. But I don't see a reason why this should blow up like it
does. With the .Refresh, it goes straight to the error handler with
the prompt and the '1004' error.

Has anyone had this problem? If anyone has, could you help this
newb? I'm desperate.

I attached the spaghetti code below. I inherited this learning
opportunity. I'm sure you all know what that's like. It's fun. I
apologize for the following:

In case anyone else has a problem - I think we've figured it out.
The OLEDB driver has an issue with the refresh statement, and we
changed the connection to an ODBC connection.
We also had a "timing" issue with the database, so we put in some
waits after the refresh background query statements, and then a cancel
refresh to get around the problem.
