Hi
Jared,
Thanks for your response.
different results mean that number of records are different sometimes, and
sometimes the some of the quantities are not correct. Your help is really
appreciated.
Thanks,
Rajesh
Q: What does "different results" mean?
Different row count?
Completely different data?
Partially different data?
Some columns have incorrect value?
What about doing it without the parallel hints?
The tables aren't
so big that it
would take a long time to find out.
Jared

Riddle |
Hi All,
The
following query is giving different results in each run. I assure that no data
modified between consecutive runs -
INSERT /* append parallel (z,8) */
INTO some_table
(SELECT /*parallel (a,8)
*/
a.item,
a.loc,
SUM(a.qty_type_1),
SUM(a.qty_type_2)
FROM
(select
/*parallel (x,8) */
item,
loc,
qty_type_1,
to_number(NULL)
from
table_a x
UNION ALL
select /*parallel (y,8)
*/
item,
loc,
to_number(NULL),
qty_type_2
from
table_b y
) a
GROUP BY
a.item,
a.loc);
Additional info -
Number of records in table_a
and table_b is around 3M and 6M.
SQL> select * from
v$version;
