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
(
@intCounterint
,
@lngUserIDint)

as
select Top 5 lngWorkID,strWorkName,strExecHumanName,strBeginDate
from worklist where lngExecHumanID=@lngUserID
orderby lngWorkID desc

现在想将这里的Top 5 改为变量· Top @intCounter
如下

ALTER proc getWorkPlan2
(
@intCounterint
,
@lngUserIDint)
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

ALTERproc 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
