存儲過程中使用臨時表

CREATE PROCEDURE [dbo].[usp_UserFriendsOrder]  
 @s varchar(MAX)  
as
--如果臨時表存在則先刪除
if exists(select * from dbo.sysobjects where object_id('tempdb.dbo.#temp') is not null)
 delete from #temp
else
  create table #temp(F_ID int,F_UserID char(36),F_FatherID int,F_Code varchar(18),F_UserName varchar(20),F_Phone varchar(11),F_CreateUser char(36),F_CreateDate datetime, F_State int,F_Uplevel varchar(8000),F_DownLevel varchar(8000),F_Level int)
  --執行存儲過程usp_TUserRelationByFID 放入臨時表
  insert into #temp exec usp_TUserRelationByFID @s
  --查詢臨時表
   -- select * from #temp 
BEGIN
 -- A.Currentcount 本月消費條數
 -- B.Lastcount    上月消費條數
declare  @sqlf_id varchar(MAX) 
set @sqlf_id='SELECT  ltrim(Convert(numeric(9,2),case when B.Lastcount=0 then 0 else A.Currentcount*100.0/B.Lastcount end))+''%'' As Percentage, A.Currentcount,B.Lastcount  FROM (SELECT      count(*) as Currentcount
