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.
do you want
1 | 2 | 3
or
1
2
3
as your result? the first is a join, the 2nd is a union.
