No, I did not see anything in object_node column. Here is the output. SQL >select distinct statement_id, object_node from plan_table; STATEMENT_ID OBJECT_NODE ------------------------------ --------------------------------------------------------------------- Wrong_results Thanks.

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.

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 Jared Prasada.Gunda@xxxxxxxxxxxxxxxx To: Sent by: oracle-l@xxxxxxxxxxxxx oracle-l-bounce@xxxxxxxxxxxxx cc: Subject: Query returning wrong results. 03/18/2004 11:31 AM Please respond to oracle-l 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' union all select a1.col1 , to_date('01/01/1900','mm/dd/yyyy') row_eff_date , trunc(a1.col2) row_term_date from table1 a1 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 ) -- Inline view ends. ) v where ( 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.
