Title: RE: Wrong Results Bug in Oracle 8.1.7.1

That's it.  The init.ora parameter, IGNORE_IN_INDEX  had been set to TRUE, but the indexes had not been rebuilt

We had a similar issue, although it always resulted in an ORA-600.  It was with descending indexes as defined in the Peopletools repository.  We had to set _IGNORE_DESC_IN_INDEX=TRUE (and _DB_FILE_NONCONTIG_MBLOCK_READ_COUNT=1 to comply with the Certification Requirements) and recreate the development databases.  For Production, PS Support gave the OK to recreate the indexes without having to redo the upgrade.

Accounts payable.  But this is not a Peoplesoft problem, but an Oracle one.  I tried the same query against another Peoplesoft instance, and it ran fine.  So there's something more than the view involved here.  It's in Oracle Support's court now.

I must be living right.  It's failing in development and working in production.
