Errors after migration application to Apex 4.0

edited May 2, 2011 9:25PM in Oracle Application Express (MOSC) 2 commentsAnswered
I've recently set up a new server, and took the opportunity to upgrade to Apex 4.0

After migrating my application from my old server (Apex 3) where the app worked perfectly, I am now getting these errors: 

 ORA-06550: line 1, column 31: PL/SQL: ORA-00918: column ambiguously defined ORA-00918: column ambiguously defined ORA-06550: line 1, column 7: PL/SQL: SQL Statement ignored ORA-00918: column ambiguously defined

on almost all pages that have a query on them.  Of course, running the query stand-alone it works fine.

I'm not sure how to debug this.  Showing debug information doesn't show anything that seems to indicate the cause.

Can anyone offer suggestions on what to look for here?

Howdy, Stranger!
