SQL Server – use a parameter to select the top X of the result set

My query in my stored procedure looks something like:

select top 9 from my_table;

I’d like to edit the stored procedure to dynamically produce the limit from a parameter, however, this does not seem to be working:

ALTER PROCEDURE [dbo].[my_stored_procedure]
   @n INT(2)
AS
BEGIN

SELECT TOP @n from my_table;

Is this doable? Or do I have to do something like:

@n int(2),
@sql varchar(30)

@sql = 'select top ' + @n '* from my table';
exec(@sql);

Thanks.

You have to enclose the parameter in parenthesis like:

DECLARE @QQ INT = 10

SELECT  TOP (@QQ)
        *

FROM    Your_Table
