Re: Convert 2 foreign key values within the same SELECT - Mailing list pgsql-general
Does this work?
SELECT l.me_id AS me,
l.you_id AS you,
a.l AS left,
a.aspect,
a.r AS right,
l.id AS link_id,
c.comment,
concat(m.first_name, ' ', m.surname) AS me_name,
concat(y.first_name, ' ', y.surname) AS you_name
FROM aspects a,
links_aspects la,
links l,
syn_comments c
JOIN users m ON l.me = m.id
JOIN users y on l.you = y.id
WHERE (a.r = 'Venus' AND a.l = 'Venus')
AND a.type = 'synastry'
AND la.aspect_id = a.id
AND la.id = c.links_aspects_id
AND la.link_id = l.id;
SELECT l.me_id AS me,
l.you_id AS you,
a.l AS left,
a.aspect,
a.r AS right,
l.id AS link_id,
c.comment,
concat(m.first_name, ' ', m.surname) AS me_name,
concat(y.first_name, ' ', y.surname) AS you_name
FROM aspects a,
links_aspects la,
links l,
syn_comments c
JOIN users m ON l.me = m.id
JOIN users y on l.you = y.id
WHERE (a.r = 'Venus' AND a.l = 'Venus')
AND a.type = 'synastry'
AND la.aspect_id = a.id
AND la.id = c.links_aspects_id
AND la.link_id = l.id;

..... however, l.me_id and l.you_id are foreign keys referencing a users table from which I would like to retrieve concat(u.first_name, ' ', u.surname) AS name for l.me_id and l.you_id. It seems simple but I can't think of a JOIN which will do the trick.
