我写的一个存储过程,怎么执行速度比在查询分析器的慢很多呀?

Question

而且在查询分析器里运行的语句就是存储过程里的内容,
只不过把@StubsDate定义了一个变量!大家快帮忙呀!!!!

Answer 1

to wangtiecheng(cappuccino) 我在事件探查器中监视,
就只显示 存储过程总执行的时间,166秒,没有显示存储过程里面的各语句的执行时间呀!!!!

Answer 2

在查询分析器中分别执行存储过程和SQL语句，查看执行计划

Answer 3

把菜单里那个
--->query----->show excution plan
选项打开.

Answer 4

to libin_ftsafe(子陌红尘) :
多谢了,用表变量是可以提高执行时间了,只不过还要40多秒的,奇怪了,
我把上面的存储过程分成两个,把临时表变成表只执行时间只要2秒了
奇怪了,有哪位大侠遇到过这种情况!我的存储过程如下CREATE procedure [pr_StubsA_1]
@StubsDate DatetimeASSET NOCOUNT ON--如果已有结存记录,则删除重新结存
if ((Select count(*) From StubsA Where Datediff(m,SDate,@StubsDate)=0)>0) 
  Delete From StubsA Where Datediff(m,SDate,@StubsDate)=0
--清空临时表
Truncate Table StubsTemp1
--CREATE TABLE #StubsTemp1 (GoodID INT PRIMARY KEY)
--添加上月结存表里的GoodID
Insert into StubsTemp1 Select GoodID From StubsA Where Datediff(m,SDate,@StubsDate)=1 and (SNum<>0)--添加当月入库的GoodID
Insert into StubsTemp1 Select Distinct GoodID From DetsAViewI Where Datediff(m,BDate,@StubsDate)=0 and StorID=1 and GoodID not in (Select GoodID From StubsTemp1)SET NOCOUNT OFF
GO
CREATE procedure [pr_StubsA_2]
@StubsDate DatetimeASSET NOCOUNT ONInsert into StubsA Select 
@StubsDate,GoodID,--上月库存
isnull((Select SNum From StubsA Where  Datediff(m,SDate,@StubsDate)=1 and StubsA.GoodID=StubsTemp1.GoodID),0) as LNum,
isnull((Select SWeight From StubsA Where  Datediff(m,SDate,@StubsDate)=1 and StubsA.GoodID=StubsTemp1.GoodID),0) as LWeight,
isnull((Select SMoney From StubsA Where  Datediff(m,SDate,@StubsDate)=1 and StubsA.GoodID=StubsTemp1.GoodID),0) as LMoney,
--当月正常入库(包括退库的方材)
(Select isnull(Sum(GNum*(case when typeid=1 then 1 else -1 end)),0) From DetsAViewI Where Datediff(m,BDate,@StubsDate)=0 and TypeID in (1,10) and DetsAViewI.GoodID=StubsTemp1.GoodID) as InNum,
(Select isnull(Sum(GWeight*(case when typeid=1 then 1 else -1 end)),0) From DetsAViewI Where Datediff(m,BDate,@StubsDate)=0 and  TypeID in (1,10) and DetsAViewI.GoodID=StubsTemp1.GoodID) as InWeight,
(Select isnull(Sum(GMoney*(case when typeid=1 then 1 else -1 end)),0) From DetsAViewI Where Datediff(m,BDate,@StubsDate)=0 and  TypeID in (1,10) and DetsAViewI.GoodID=StubsTemp1.GoodID) as InMoney,
--当月其他入库
(Select isnull(Sum(GNum),0) From DetsAViewI Where Datediff(m,BDate,@StubsDate)=0 and  TypeID=3 and DetsAViewI.GoodID=StubsTemp1.GoodID) as InNum1,
(Select isnull(Sum(GWeight),0) From DetsAViewI Where Datediff(m,BDate,@StubsDate)=0 and TypeID=3 and DetsAViewI.GoodID=StubsTemp1.GoodID) as InWeight1,
(Select isnull(Sum(GMoney),0) From DetsAViewI Where Datediff(m,BDate,@StubsDate)=0 and TypeID=3 and DetsAViewI.GoodID=StubsTemp1.GoodID) as InMoney1,
--当月正常出库
(Select isnull(Sum(GNum),0) From DetsAViewO Where Datediff(m,BDate,@StubsDate)=0 and TypeID=2 and DetsAViewO.GoodID=StubsTemp1.GoodID) as OutNum,
(Select isnull(Sum(GWeight),0) From DetsAViewO Where Datediff(m,BDate,@StubsDate)=0 and TypeID=2 and DetsAViewO.GoodID=StubsTemp1.GoodID) as OutWeight,
(Select isnull(Sum(GMoney),0) From DetsAViewO Where Datediff(m,BDate,@StubsDate)=0 and TypeID=2 and DetsAViewO.GoodID=StubsTemp1.GoodID) as OutMoney,
--当月其他出库
(Select isnull(Sum(GNum),0) From DetsAViewO Where Datediff(m,BDate,@StubsDate)=0 and TypeID=4 and DetsAViewO.GoodID=StubsTemp1.GoodID) as OutNum1,
(Select isnull(Sum(GWeight),0) From DetsAViewO Where Datediff(m,BDate,@StubsDate)=0 and TypeID=4 and DetsAViewO.GoodID=StubsTemp1.GoodID) as OutWeight1,
(Select isnull(Sum(GMoney),0) From DetsAViewO Where Datediff(m,BDate,@StubsDate)=0 and TypeID=4 and DetsAViewO.GoodID=StubsTemp1.GoodID) as OutMoney1,
--当月库存
0,0,0
From StubsTemp1 SET NOCOUNT OFF
GO然后在查询分析器里执行
exec pr_stubsa_1 '2006-3-1'
exec pr_stubsa_2 '2006-3-1'
只要2秒哪位大侠给解释一下?
