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