Krzysztof Wo¼nica (kw@b3.4it.pl) reports a bug with a severity of 2
The lower the number the more severe it is.
Short Description
strange select results
Long Description
I have created an view. When I select fields separately all looks ok but when I try to select 3 fields for concatention
(f1|| f2 || f3) the resul is empty when f3 is empty. I think it is not expected bahaviour.
Sample Code
the view:
SELECT person.id, person.sex, person.salutation, person.firstname, person.secondname, person.lastname, person.birthday,
person.number,person.nip, (SELECT ((((((((address.street || ' '::text) || btrim((address.building)::text, ' '::text))
||'/'::text) || btrim((address.apartament)::text, ' '::text)) || ', '::text) || address.city) || ', '::text) ||
(address.country)::text)FROM address WHERE (((address.personid = person.id) AND (((address.fromdate <
'2003-01-02'::date)OR (address.todate IS NULL)) AND ((address.todate > '2003-01-02'::date) OR (address.todate IS
NULL))))AND (address."primary" = 't'::bool)) LIMIT 1) AS address, (SELECT contact.howto FROM contact WHERE
(((contact.personid= person.id) AND ((contact."type" = 'cel'::bpchar) OR (contact."type" = 'pho'::bpchar))) AND
(((contact.fromdate< '2003-01-02'::date) OR (contact.fromdate IS NULL)) AND ((contact.todate > '2003-01-02'::date) OR
(contact.todateIS NULL)))) LIMIT 1) AS phone, (SELECT contact.howto FROM contact
WHERE (((contact.personid = person.id) AND (contact."type" = 'eml'::bpchar)) AND (((contact.fromdate <
'2003-01-02'::date)OR (contact.fromdate IS NULL)) AND ((contact.todate > '2003-01-02'::date) OR (contact.todate IS
NULL))))LIMIT 1) AS email FROM person;
