hi,
thats the first time I am a bit confused by a query not working.
I have this table:
gullevek=# \d test
Table "public.test"
Column | Type | Modifiers
---------+-------------------+--------------------------------------------------------
test_id | integer | not null default
nextval('test_test_id_seq'::regclass)
email_a | character varying |
email_b | character varying |
Indexes:
"test_pkey" PRIMARY KEY, btree (test_id)
with this content:
gullevek=# select * from test;
test_id | email_a | email_b
---------+---------------+-------------
2 | test@xxxxxxxx | bar@xxxxxxx
1 | foo@xxxxxxx |
(2 rows)
if I do this select:
select * from (select test_id, email_a FROM test WHERE email_a =
'moo@xxxxxxx') as s, (select test_id, email_b from test where email_b =
'bar@xxxxxxx') as t;
I get no rows back. should it return something? subquery a doesn't
return one, because the email does not exist, b returns something.
how do I have to make the query so I get a result back and in one row?
