When you do explain plan for the sql, do you see any ":Q" in the object_node
column?

Thanks Jared, Waleed and David for your replies.
It is not using PQO (but parallel_automatic_tuning is set to TRUE). Table has degree 1. Also tested with noparallel hint and no_merge hints, it is returning same wrong results.
DB is 8.1.7.4 and It is on Hp-Unix v11.
David : Inline view is returning 3 records and only one record satisfies the outer filter predicate.
I will do more research on metalink and will update you all if I find anything relevant.
Best Regards,
Prasad

Please respond to
oracle-l
Looks like a bug. If you provide some platform and version information someone may have an idea as to which bug.
Better yet, check on MetaLink for related bugs.
If it is a parallel query it could be bug 1759227

Hi,
One of our developer sent me this query that it is returning wrong results. Please see the following query.
select v.col1, v.row_eff_date, v.row_term_date
from
( -- Inline view begins
select a.col1
, trunc(a.col2) row_eff_date
, nvl(lead(trunc(a.col2)) over
(partition by a.col1, a.tblnm, a.clmnnm order by a.col2),to_date ('12/31/2999','mm/dd/yyyy')) row_term_date from table1 a
where a.tblnm = 'INPUT_TABLE' and a.clmnnm = 'INPUT_COL' and a.col1 = '10000151'
where a1.tblnm = 'INPUT_TABLE'
and a1.clmnnm = 'INPUT_COL'
and a1.col1 = '10000151'
and (a1.col1, a1.col2) IN
(select octl1.col1, min(octl1.col2)
from table1 octl1
where octl1.tblnm ='INPUT_TABLE'
and octl1.clmnnm ='INPUT_COL'
group by octl1.col1
)
trunc(v.row_eff_date) > to_date('03/14/2004','MM/DD/YYYY') OR trunc(v.row_term_date) = to_date('12/31/2999','MM/DD/YYYY') )
If I run inline view on its own, it returns 3 records.
COL1 ROW_EFF_DAT ROW_TERM_DA
------------ ----------- ----------- 10000151 01-jan-1900 13-dec-2002 10000151 13-dec-2002 23-jan-2003 10000151 23-jan-2003 31-dec-2999
If I run the entire sql, it suppose to return the following record.
COL1 ROW_EFF_DAT ROW_TERM_DA
------------ ----------- -----------
10000151 23-jan-2003 31-dec-2999
But, the query returns the following two records which is wrong.
COL1 ROW_EFF_DAT ROW_TERM_DA
------------ ----------- ----------- 10000151 13-dec-2002 23-jan-2003 10000151 23-jan-2003 31-dec-2999
Did anybody experience this before. I kind of remember that it is something to do with analytical function but I can not recall. For the purpose of testing, when I created a table out of inner sql and used that table in the inner query, it works fine. The DB is 8.1.7.4 on Hp-unix v11. I also opened a TAR and will update the status to the List.
Thanks in advance.
Best regards,
Prasad
