存储过程中的top+变量

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。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 '
)

OK!

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
