declare @n int,

@s-2 varchar(1000)

set @n=10

set @s-2 ='select min(your_field) from your_table where your_field in

(select top ' + convert(varchar(10,@n) + ' your_field from your_table order by...

An other solution is:

declare @n int

select min(your_field) from your_table where your_field in

(select top @n your_field from your_table order by your_field desc)

For me is more elegant.
