Wrong Result With Partitioned Table (Doc ID 1316789.1)

Last updated on FEBRUARY 03, 2019

Applies to:

Oracle Server - Enterprise Edition - Version: 10.2.0.1 to 11.1.0.7 - Release: 10.2 to 11.1
Information in this document applies to any platform.

Symptoms

While querying and using a partitioned table, then the wrong result occurs, for example:

1) Run query:

SQL> select trunc(sysdate-NNN,'dd'), to_date('01.11.2010','dd.mm.yyyy') from dual;

You should replace NNN with proper number so that query returns equal values,
for today it is 170

2) Query:

SQL> select * from cis_bonuses_tst cs where cs.subs_subs_id=21032611 and
cs.del_date is not null and cs.cgro_cgro_id=1 and
cs.del_date>=to_date('01.11.2010','dd.mm.yyyy');

return 26 rows.

3) Query:

SQL> select * from cis_bonuses_tst cs where cs.subs_subs_id=21032611 and
cs.del_date is not null and cs.cgro_cgro_id=1 and
cs.del_date>=trunc(sysdate-NNN,'dd');

return 0 rows (NNN - number from first step).
