Hello
Can I write a query where I receive a single result set from many
queries?
Something like this: SELECT (SELECT 1 AS t1, 2 AS t2), (SELECT 3 AS t3)
I tried exactly this but the error is: "ERROR: subquery must return
only one column"
But I don't see why it must have only one column.

postgres(at)test=# SELECT * from (SELECT 1 AS t1, 2 AS t2) as t, (SELECT 3
AS t3) as s;
t1 | t2 | t3
----+----+----
1 | 2 | 3

Thank you
