RE: create a view with parallel hint

Tony,

You need to use global hints.  Check the Performance Tuning manual for
details; 10g version is at
http://download.oracle.com/docs/cd/B19306_01/server.102/b14211/hintsref.

Subject: create a view with parallel hint

Hi folks,

After some tuning I went back to the developer and recommended a new
super version, slightly changed and including a full and a parallel
hint.   The new query runs in 5 mins vs 68mins for the old, so a
result.

The problem I have is that query is generated by Crystal Reports.
Currently we don't know how we can include the hints in the report
(the developer is looking into this as I type).

To work around this problem I created a view that includes the hints,
and then changed the main query to use the query instead of the
original table.

Something like this....

create or replace view EVENT_T_parallel_historic as
select * /*+ full(eph) parallel(eph,8) */
from
EVENT_T partition (PARTITION_HISTORIC) eph;

then reference EVENT_T_parallel_historic in the main query.

But,... when I run the query, the hints are ignored.

Can hints be used within views in this manner, and/or am I doing
something wrong here?

Any pointers appreciated.

Cheers
Tony
