Is it possible to write out to a Stored Procedure in this format, where I am passing in a parameter of 10 or 20 etc so I can pull out the top 10 or 20:

Create Stored Procedure spsh_Test
(
@nText INT
)

Select
TOP @nText myField
FROM
myTable
GO

TOP doesn't accept a variable yet, it will in SQL 2005.

Until then, we can use rowcount.

SET ROWCOUNT @nText

SELECT myField FROM myTable

SET ROWCOUNT 0

I think top can accept variable if we use Dynamic SQL

Create Procedure Returntop (@topno integer)
as
Create table #t(i integer identity,n char(10))
insert into #t(n) values('test1')
insert into #t(n) values('test2')
insert into #t(n) values('test3')
insert into #t(n) values('test4')
insert into #t(n) values('test5')
insert into #t(n) values('test6')
insert into #t(n) values('test7')
insert into #t(n) values('test8')
insert into #t(n) values('test9')
insert into #t(n) values('test10')
Exec('select top '+@topno +' * from #t')

Run
ReturnTop 5 -- will return top 5
ReturnTop 7 -- will return top 7

Yes, but
1. That isn't top accepting a variable param, it's executing a string
2. It's silly, we've already solved that problem.
