Question

The issue here is suppose if i want to use two queries seperated by UNION, the query is as

             $query=(select a.name,a.age,b.country,b.state from a,b where a.aid=b.bid)  UNION (select a.name,a.age,c.profession,c.salary from a,c where a.anid=c.cid)

here the result would only show the first query’s result , Any way in which i could display the result of 2nd query also down to the result of first query using UNION. Expecting any help on this. Thanks

Answer 1

Are you after

(
  select a.name,a.age,b.country,b.state,null as profession,null as salary 
  from a,b
  where a.aid=b.bid
)  
UNION 
(
   select a.name,a.age,null,null,c.profession,c.salary
   from a,c
   where a.anid=c.cid
)

You will have null in the profession and salary columns from the first query and null in country and state columns in the second query
