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 BarFredNoYes
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 nullanswer | 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.
