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.
