Is it possible to rewrite this SQL query so it returns one row having
the columns title and contentType, instead of two rows with the sname
column? I could write a stored procedure to lookup the title or
content-type based on the rec_id, but I would rather do it in a single
query if it's possible.
# SELECT rec_id, url, sname, sval FROM url, urlinfo
WHERE url.rec_id = 1821
AND url.rec_id = urlinfo.url_id
AND sname in('title','Content-Type');
rec_id | url | sname | sval
-------+--------------
+--------------------------------------------------------- 1821 | http://.../ | title | Architectural Research
Consultants, Incorporated Contact Information 1821 | http://.../ | Content-Type | text/html
(2 rows)
mnogosearch=> \d urlinfo Table "public.urlinfo" Column | Type | Modifiers
--------+---------+----------- url_id | integer | not null sname | text | not null sval | text | not null
Indexes: urlinfo_id btree (url_id)
