The idea is this:

SQL

select 
 fa.facname
,f.bfid
,b.class
,b.examdate 
from 
bthfac f
inner join batch b on b.bthid = f.bthid
inner join facfeedback fb on fb.bfid=f.bfid
inner join faculty fa on fa.????=??.????
where 
 month(b.examdate)= '11' 
 and year(b.examdate)= '2012' 
 and fa.facname = 'MADHAVAN'

But be aware, that you select from faculty table without any join to the other tables. That look like a problem to me. But as I don't know the relations between the tables, I can not suggest you more. Of course, it might happen that you need something else than inner join, but that is more likely. When you select from a table without join or equivalent where condition you produce a Cartesian product - and it is unlikely that you need something like that in this situation.
