Using Parameter with Select Top @TopNum

For a query like this:
Select Top 1000 Names from People order by Age

Is there a way I can pass the number that I want to show, in as a Parameter.
Select Top @TopNum Names from People order by Age
doesn't work.


you can use a stored procedure with parameter ..

create stored procedure SP_Name ... @TopNum Paramater
declare @sql nvarchar(max) = ''
set @sql = 'select top '+@TopNum + ' Names from People Order by Age '

to execute stored procedure ..
exec SP_Name (500)

You can directly use a variable. Note that the parentheses around the value is the correct syntax, you should always use them, even with a literal number, such as ... TOP (50) ...:

Declare @TopNum int
Set @TopNum = 1000

Select Top (@TopNum) Names from People order by Age
