Question

Answer 1

Union will fetch data by row not column,So If your are like me who is looking for fetching column data from two different table with no relation and without join.
In my case I am fetching state name and country name by id. Instead of writing two query you can do this way.

select 
   (
   select s.state_name from state s where s.state_id=3
   ) statename,
   (
   select c.description from country c where c.id=5
   ) countryname
   from dual;   

where dual is a dummy table with single column--anything just require table to view
