存储过程中的top+变量(downmoon)

存储过程中的TOP后跟一个变量会如何？

Create   proc  getWorkPlan2 ( @intCounter   int , @lngUserID   int ) as select   Top   5  lngWorkID,strWorkName,strExecHumanName,strBeginDate from  worklist  where  lngExecHumanID =   @lngUserID order   by  lngWorkID  desc

现在想将这里的Top　5 改为变量· Top @intCounter 如下

ALTER   proc  getWorkPlan2 ( @intCounter   int , @lngUserID   int ) as  　 ) exec 　sp_executesql ( ' select Top  ' + convert ( varchar ( 10 ), @intCounter ) + '  lngWorkID,strWorkName,strExecHumanName,strBeginDate from worklist where lngExecHumanID=  ' + convert ( varchar ( 10 ), @lngUserID )  + '  order by lngWorkID desc  ' 老是提示　在关键字 'convert' 附近有语法错误。 OK! 于是改为 ALTER   proc  getWorkPlan2 ( @intCounter   int , @lngUserID   int ) as declare   @strCounter   varchar ( 10 ) set   @strCounter = convert ( varchar ( 10 ), @intCounter ) declare   @strUserID   varchar ( 10 ) set   @strUserID = convert ( varchar ( 10 ), @lngUserID ) exec 　sp_executesql ( ' select Top  ' + @strCounter + '  lngWorkID,strWorkName,strExecHumanName,strBeginDate from worklist where lngExecHumanID=  ' + @strUserID   + '  order by lngWorkID desc  ' )

 后来，经saucer(思归)大哥提醒，发现可以用以下语句实现(sql2005/2008)： 

Alter   proc  getWorkPlan2
(
@intCounter   int
, @lngUserID   int
)
as
set   rowcount   @intCounter
select   lngWorkID,strWorkName,strExecHumanName,strBeginDate
from  worklist  where  lngExecHumanID =   @lngUserID
order   by  lngWorkID  desc
