Join two sql queries side by side with no column common - sql

Question

I need to join the results of two queries horizontally.
Consider a query below which will return two rows:
Select *
from Salary
where sal > 10000
The result of the query above should be joined side by side with the result of the query below which will again return two rows.Or I need to just concatenate the two result sets:
Select 'xyz' from dual
union
Select 'abc' from dual
Please suggest how this can be done as I tried to do this with the query below but it returns a cartesian product:
Select *
from (Select *
from salary
where sal > 10000) TEMP1,
(Select 'xyz' from dual
union
Select 'abc' from dual) TEMP2

Answer 1

You can do that by joining on rownum like this:
SELECT *
FROM
(SELECT view_name, rownum AS r FROM all_views WHERE rownum <=10)
FULL OUTER JOIN (SELECT table_name, rownum AS r FROM all_tables WHERE rownum <=10) USING (r)
In your case this would look like (untested):
Select * from
(Select salary.*, rownum AS r from salary where sal>10000) TEMP1
FULL OUTER JOIN
(SELECT temp2.*, rownum r FROM
(Select 'xyz' from dual
union
Select 'abc' from dual) TEMP2)
USING (r)

Answer 2

you can introduce an artificial join column:
SELECT *
FROM (SELECT s.*, ROWNUM ID FROM Salary s WHERE sal > 10000) q1
JOIN (SELECT 'xyz' col1, 1 ID
FROM dual
UNION
SELECT 'abc' col1, 2 ID FROM dual) q2 ON q1.id = q2.id

Answer 3

Thank you very much for your help.
But what I need is a bit complicated. I have updated the previous query to be somewhat like below instead of simple query that I posted before (SELECT * FROM Salary WHERE sal > 10000):
SELECT name, sal, address
FROM (SELECT e1.name, s1.sal, s1.grade, s2.address FROM Emp e1, salary s1,
(Select empcode, address FROM Address WHERE empcode LIKE 'NY%') s2
WHERE e1.hiredate =201001
AND s1.sal>10000)
I know the above query does not make much of a relevance. However, this is similar to what I need actually. I am not posting the original one as that is very complicated but if this can be done for this query, then I will be able to replicate the same on the original one as well.
Thank you,
