ordering problems ...

Hello everyone,

I have two tables :

question_response and question_response_answer.

There is a one to many relationship between the question_response and a
question_response_answer (schema below at the bottom).

When I execute :

select answer from question_response_answer qra, question_response qr
WHERE qr.response_id = qra.response_id AND qr.personal_id =
'XXYYTEST2' AND qr.module_code = 'TEST990' AND qr.assessment_id = 109
AND qr.question_id = 125 ;

I get :

answer
---------
Foo Bar
Fred
No
Yes

When I execute :

select * from question_response_answer;

I get :

response_id | answer
-------------+------------
148 | Yes
148 | No
148 | Fred
148 | Foo Bar

I'd like to know why the ordering has changed, and is there anything I can do make it the same as it is on the "select * from question_response_answer" "version" ?

Running Postgres 7.3.2 on Linux.

Schema :
Column | Type | Modifiers
---------------+----------------------+--------------------------------------------------------
response_id | integer | not null default
nextval('question_reponse_seq'::text)
question_id | integer |
personal_id | character varying(9) |
assessment_id | integer |
module_code | character varying(9) |
Indexes: question_response_pkey primary key btree (response_id),
question_response_question_id_key unique btree (question_id,
personal_id, assessment_id)

(there are foreign keys, but I've left them off)

tweektest=> \d question_response_answer;
Table "public.question_response_answer"
Column | Type | Modifiers
-------------+---------+-----------
response_id | integer | not null
answer | text | not null
Indexes: question_response_answer_pkey primary key btree (response_id,
answer)
Foreign Key constraints: $1 FOREIGN KEY (response_id) REFERENCES
question_response(response_id) ON UPDATE NO ACTION ON DELETE CASCADE

Thanks in advance,
David.
