See if the table was created using parallel slaves.
The last time I had such issue was with 9.2.0.4 (or 3) when PX and hash
joins broke when used together, when I disabled any one of them, everything
worked fine.
If disabling parallelism doesn't help then I'd set
optimizer_features_enabled to lower value and tried again.
And of course there's this Oracle's unbreakable site called metalink. As
you're on 10.2 and can produce a test case, you should get this bug fixed
alright..
Tanel.
As there seem to a few people using 10.2 (10.2.0.2 on Solaris 9 in my case) I thought I'd share a scary issue with you all.
Odd in the example below is a reasonably complex view that has been working fine in 10.1 for quite a while.
MP409SH2> select count(*) from odd;
COUNT(*) ---------------- 67311
Elapsed: 00:01:15.56 MP409SH2> create table very_odd as select * from odd;
Table created.
Elapsed: 00:07:34.00 MP409SH2> select count(*) from very_odd;
COUNT(*) ---------------- 1371016
Elapsed: 00:00:01.84
This is a 100% genuine case where the select statement returns the wrong (substantially) number of rows. In 10.1 the view returns the correct 67311 rows. There doesn't seem to be any pattern or reason for the error and I only noticed it because I had the 10.1 results to hand. I'll be raising a tar as soon as Metalink sorts itself out but I thought I'd share this as I'm not sure I can 100% trust the results of any select statement on 10.2
Cheers,
Ian .
