I have two tables,

SQL

student:
rollno | name
1      | Abc
2      | efg
3      | hij
4      | klm

attendance:
name | date       |statuss
Abc  | 10-10-2013 | A
efg  | 10-10-2013 | A
Abc  | 11-10-2013 | A
hij  | 25-10-2013 | A

my required output is:
some query with where condition as "where date between '10-09-2013' and '13-10-2013' "

SQL

rollno| name |count
1     | Abc  | 2
2     | efg  | 1
3     | hij  | 0
4     | klm  | 0

i tried using:

SQL

SELECT p.rollno,p.name,case when s.statuss='A' then COUNT(p.rollno) else '0' end as count from attendance s right outer join student p on s.rollno=p.rollno where s.date between '10-09-2013' and '13-10-2013' group by p.rollno,p.regno,p.name,s.statuss order by p.rollno

output is:
rollno| name |count
1     | Abc  | 2
2     | efg  | 1

i want the remaining values from the student table to also be appended,i tried many ways all are in vain,pls provide me a query which provides the output,
thanks in advance.
