存储过程中的top+变量(downmoon)sql

<!-- .lineBorderBlue1 { BORDER-TOP: #999999 1px groove; BORDER-BOTTOM: #999999 1px groove; BORDER-LEFT: #999999 1px groove; BORDER-RIGHT: #999999 1px groove; background-color:#efefef; } -->

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 ( ' selectTop ' + convert ( varchar ( 10 ), @intCounter ) + ' lngWorkID,strWorkName,strExecHumanName,strBeginDatefromworklistwherelngExecHumanID= ' + convert ( varchar ( 10 ), @lngUserID ) + ' orderbylngWorkIDdesc '

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 ( ' selectTop ' + @strCounter + ' lngWorkID,strWorkName,strExecHumanName,strBeginDatefromworklistwherelngExecHumanID= ' + @strUserID + ' orderbylngWorkIDdesc ' )

OK！

后来，经 saucer(思归) 大哥提醒，发现可以用以下语句实现(sql2005/sql2008)：

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
