Default Problem with clause Top in store procedure

Hi

I have this code

declare @count_rows int
declare @sql as varchar(8000)
set @count_rows = 2
set @sql = (select top 1 eff_dt from (select top 2 * from dbo.tabla where cod = 99 order by src_eff_dt) q order by eff_dt desc)
print 'value=' + @sql

result: value= Nov 29 2005 6:07 PM

but when I put parameters

declare @count_rows int
declare @sql as varchar(8000)
set @count_rows = 2
set @sql = (select top 1 eff_dt from (select top ' + (@count_rows) + * from dbo.tabla where cod = 99 order by src_eff_dt) q order by eff_dt desc)
print 'value=' + @sql

Could not find stored procedure, I would like confirm in this problem for SQL version 2000

Thanks a lot
Javier

You have mixed up a couple of concepts.

Since you are still using SQL Server 2000, you'll have to do something like:
Code:
CREATE PROC whatevername 
    @count_rows INT
AS
declare @sql as varchar(8000)
set @sql = 'select MAX(q.eff_dt) AS TheDt from '
         + ' (select top ' + @count_rows + ' from dbo.tabla where cod = 99 order by src_eff_dt) AS q'
EXEC ( @sql )
print 'value=' + @sql

thanks for your recommendation but I have problems with the type of data

Msg 245, Level 16, State 1, Procedure whatevername, Line 6
Syntax error converting the varchar value 'select MAX (q.eff_dt) AS TheDt from (select top' to a column of data type int.
