SQL - display different data
Hi,
Here is the table for bug:
Attribute | Type | Modifier
---------------+---------+----------------------------------------------
bug_id | integer | not null default nextval('bug_pk_seq'::text)
group_id | integer | not null default '0'
status_id | integer | not null default '0'
priority | integer | not null default '0'
category_id | integer | not null default '0'
submitted_by | integer | not null default '0'
assigned_to | integer | not null default '0'
date | integer | not null default '0'
summary | text |
details | text |
close_date | integer |
bug_group_id | integer | not null default '0'
resolution_id | integer | not null default '0'
Indices: bug_group_id,
bug_groupid_assignedto_statusid,
bug_groupid_statusid,
bug_pkey
When I get to PostgreSQL , when I typed
"Select bug_id, group_id from bug order by id"
I would all id, and group_id from the bug table.
However, when I type
"Select * from bug where bug_id=166"
No rows are returned.
What puzzled me was able to see the bug_id (166) and group_id for bug_id (166) listed when I did
"Select id, group_id from bug order by id".
Any ideas of what's going on?
Thanks in advance.

This sounds to me like the bug_pkey index is corrupted. You might try
REINDEXing it. If that fixes it, better look for reasons why it got
corrupted (bad RAM or some such would be my first bet).

Tom,
Thanks for the info. After I did vacuum of that table, I was able to get the row return by this "Select * from bug where bug_id=166" statement. Another problem I have is that a block of records (consecutive records) are disappeared from my database probably because of the index is corrupted. Is there any other way that I get those records back without doing a restore?
Thanks.
Mary
