子查询中Order By对外部查询排序的影响

Question

I have a query with sub-query getting data from other tables. Does the order by clause in sub-query also sorts the records of the outer query in the same order??

Query is of the form:

select p.email email, max(p.firstname) firstname,max(p.lastname) lastname  
from abc p, xyz c 
where p.companyid=c.companyid 
and  c.company!=''  
and locationid in (  
                   select locationid  
                   from mno tr   
                   where 1=1 
                   AND tr.inc in (7,8,9)  
                   AND tr.topic in( 'Callidus Cloud')  
                   AND tr.inc IS NOT NULL  
                   order by inc desc 
                  ) 
AND c.crange IN ('100-249','250-499','500-999','1000-4999'
                  ,'5000-9999','50000-100000','>100000') 
group by p.email limit 7 offset 0

Answer 1

What happens in sub query remains in sub query. It only returns the value you asked for.
