Symptoms

On a partitioned database in a partitioned compressed table wrong values are seen:


SQL> select rowid, COL1
2 from securitydbo.T1
3 where COL1 =
4 (
5 select min(COL1)
6 from XYZ.T1
7* )

ROWID COL1
------------------ ------------------
AABBQHABKAAAOKtAAB -8.95E-116

SQL> select nvl(COL1,-999)
2 from XYZ.T1
3 where rowid='AABBQHABKAAAOKtAAB';

NVL(COL1,-999)
----------------------------
-999


or null is seen in not null column

It was detected that moving the data "fixes" the issue.
For example moving the partition or creating a table based on the partition.

 created a table t1 as select * from the partition.


SQL> select COL2, COL3
2 from XYZ.T1 h
3 where COL4 = 110766
4 and COL5 in (40)
5 order by COL2
6 /
