--临时表的使用

转换字段，两种方法：

cast(num as int )

convert(int,num)
(select sum(cast (SquareNew as float)) as aa
from
(select 'SquareNew'=(
     case
     when ISNUMERIC ([Square])=0 then '0'
     when ISNUMERIC ([Square])>0 then [Square]
     end) from QueryMainList

)tb) as shoparea,

(select count(shopCode) from QueryMainList where RentStatus=2) as rendshop,
--总已租商铺面积
(select sum(cast (SquareNew as float)) as bb
from

     case
     when ISNUMERIC ([Square])=0 then '0'
     when ISNUMERIC ([Square])>0 then [Square]
     end) from QueryMainList

     when ISNUMERIC ([Square])>0 then [Square]
     end) from QueryMainList

)tb) as unrendshoparea,

--求百分比

--cast(cast(分子 *1.0*100/cast(cast(分母 as decimal(10,2)) as varchar(50)) +'%')
(select cast(cast((select count(shopCode) from QueryMainList where RentStatus=2) *1.0*100/cast(cast((select count(shopCode(select count(shopCode) from QueryMainList) as decimal(10,2)) as varchar(50)) +'%') as unrendpercent,

sum (distinct TotalAmount) as rendshopmoney from QueryMainList
--租赁开始日期条件
where RendStartDate between
--转换得到的日期格式：111:2012/8/27
CONVERT(varchar(100),
--获取本年的第一天日期
DATEADD(yy, DATEDIFF(yy,0,getdate()), 0) , 111

SELECT * FROM
(

SELECT
   *,
   ROW_NUMBER() OVER (ORDER BY totalshop DESC) AS RowIndex
   FROM @pt_tball
  ) tba
  WHERE RowIndex BETWEEN @pt_StartRowIndex AND @pt_EndRowIndex

--得到总数

SELECT @po_recordCount = COUNT(*)

--where Asset_ShopInfo.propertycode = @pi_PropertyCode
