not sure what you mean - maybe

;with cte as
(
select dte = convert(datetime,'20100701')
union all
select dte = DATEADD(m,1,dte) from cte where dte < '20110301'
)
select dte, DATEPART(year,dte), DATENAME(mm,dte)
from cte

==========================================
Cursors are useful if you don't know sql.
SSIS can be used in a similar way.

I am trying to retrieve counts for each month from July till march. What is the syntax for that?

select convert(varchar(6),dte), count(*)
from tbl
where convert(varchar(6),dte) between '201007' and '201103'

or if you want to cater for zero counts

;with cte as
(
select dte = convert(datetime,'20100701')
union all
select dte = DATEADD(m,1,dte) from cte where dte < '20110301'
)
select cte.dte, sum(case when tbl.dte is null then 0 else 1 end)
from cte
left join tbl
on datediff(mm,tbl.dte,cte.dte) = 0
group by cte.dte
