Parse Error - malformed SQL

Question

I am trying to debug a problem where a 'select * from' is being added to the sql statement a Visual Basic 6.0 application is sending to an Oracle 8.1.7 database. Any ideas what may be causing the problem?
The application SQL is:
SELECT max(work_order_id) AS WORK_ORDER_ID
FROM paint_workorder
WHERE work_order_id like '2003%'
Trace shows the following:
PARSING IN CURSOR #11
SELECT max(work_order_id) as WORK_ORDER_ID, paint_workorder.ROWID
FROM paint_workorder
WHERE work_order_id like :"SYS_B_0"
PARSE ERROR -- (extra select * from)
select * from SELECT max(work_order_id)AS WORK_ORDER_ID
FROM paint_workorder
WHERE work_order_id like :"SYS_B_0"
Somehow, a select * from is being added to the SQL statement being used by the appliciation.
System configuration is:
CLIENT:
Windows 2000 Professional Service Pack 3
Visual Basic 6.0
Oracle 8.1.7 client
ADO 2.7 & 2.8
Microsoft OLE DB provider
Server:
Oracle 8.1.7
Any help is appreciated.

Answer 1

Thanks for the reply. We started using the Oracle Provider and got past the malformed SQL problem; however, we are using some grids that started to complain about not having the Microsoft OLE DB.
We are now maintaining two connections to the database. One using the Oracle provider and one using the Microsoft provider. This is working in most areas; however we are still having problems managing two connections in the application.
At my development/QA site, I have 7 clients using the Microsoft provider connecting to the database with no problems. It is at the customer site where the problem occurs and I cannot reproduce it at the development site.
We ran tool which lists the dlls my application uses and we seem to be synched up in both locations.
Any ideas?
Thanks
