I have run into a performance issue that I can't find any
information on. There is a query that has a case statement in it. We
added indexes to the fields being referenced in the case statement, but
Oracle doesn't use the indexes. I added hints to the SQL to force it to
use the indexes, it still won't do it. I am wondering if the optimizer
realizes that the fields are being referenced, since they are inside the
case. It wants to do a full table scan each time. I can get it to use
an index on the same table, if I specify and index on a field outside of
the case.
Required information:
Oracle Version: 8.1.7.0.0
Platform: Sun Solaris 2.8
Thank you,
