वास्तविक क्वेरी:

select 
  label, 
  balls 
  from ( 
     SELECT  
       (DATEDIFF(d , '11/21/2013' , date) / 7) as week,

       LEFT(CONVERT(VARCHAR, (DateAdd(d, (DATEDIFF(d , '11/21/2013' , date) / 7)*7, '11/21/2013')), 120), 10) +    ' - ' +  
       LEFT(CONVERT(VARCHAR, (DateAdd(d, ((DATEDIFF(d , '11/21/2013' , date) / 7) + 1)*7 - 1, '11/21/2013')), 120), 10) as label, 
       SUM(Balls) as balls 
      FROM test 
      GROUP BY rollup((DATEDIFF(d , '11/21/2013' , date) / 7))
