无法在查询结果中获得单个日期 [英] not able to get individual date in query result

问题描述

我的查询是:

SELECT   sauda_date,Scrip_Code,
SUM(CASE WHEN Buy_sell = 1 THEN Trade_Qty ELSE 0 END) AS BuyQty, 
SUM(CASE WHEN Buy_sell = 1 THEN Market_Rate ELSE 0 END) AS BuyRate, 
SUM(CASE WHEN Buy_sell = 1 THEN Trade_Qty * Market_Rate ELSE 0 END) 
AS BuyAmount,
SUM(CASE WHEN Buy_sell = 2 THEN Trade_Qty ELSE 0 END) AS SellQty, 
SUM(CASE WHEN Buy_sell = 2 THEN Market_Rate ELSE 0 END) AS SellRate,
(CASE WHEN SUM(CASE WHEN Buy_sell = 1 THEN Trade_Qty ELSE 0 END)
>SUM(CASE WHEN Buy_sell = 2 THEN Trade_Qty ELSE 0 END) 
THEN 'BF' ELSE 'BT' END ) as TradeType, 
SUM(CASE WHEN Buy_sell = 2 THEN Trade_Qty * Market_Rate ELSE 0 END) AS SellAmount, 
SUM(CASE WHEN Buy_sell = 1 THEN Trade_Qty ELSE 0 END)-
SUM(CASE WHEN Buy_sell = 2 THEN Trade_Qty ELSE 0 END) as NETQTY,
SUM(CASE WHEN Buy_sell = 1 THEN Trade_Qty * Market_Rate ELSE 0 END)-
SUM(CASE WHEN Buy_sell = 2 THEN Trade_Qty * Market_Rate ELSE 0 END)as NetAmt,
SUM(CASE WHEN Buy_sell = 2 THEN Trade_Qty * Market_Rate ELSE 0 END)-
SUM(CASE WHEN Buy_sell = 1 THEN Trade_Qty * Market_Rate ELSE 0 END) as PNLAmt 
FROM tradeFile where Inst_Type='FUTIDX' OR Inst_Type='FUTSTK' 
  and Sauda_Date between convert(datetime,'1 Mar 2013') 
  and convert(datetime,'4 Mar 2013') group by Scrip_Code,ExpiryDate,sauda_date

通过此查询，我得到的结果为:

正如我们在2013-03-11所看到的，有很多记录. 我想将它们的总和用于BuyQty，SellQty等列. 即按日期的总和记录为

As we can see at 2013-03-11 there are multple records. I wanted to have their sum for BuyQty,SellQty,etc columns. i.e. Datewise sum record as

sauda_date  scrip_code  BuyQty
2013-03-11   BANKNIFTY   150 [sum for this date]

我已经尝试过:

SELECT Scrip_Code,sauda_date,
SUM(CASE WHEN Buy_sell = 1 THEN Trade_Qty ELSE 0 END) AS BuyQty,
SUM(CASE WHEN Buy_sell = 1 THEN Market_Rate ELSE 0 END) AS BuyRate,
SUM(CASE WHEN Buy_sell = 1 THEN Trade_Qty * Market_Rate ELSE 0 END)
AS BuyAmount,
SUM(CASE WHEN Buy_sell = 2 THEN Trade_Qty ELSE 0 END) AS SellQty,
SUM(CASE WHEN Buy_sell = 2 THEN Market_Rate ELSE 0 END) AS SellRate,
(CASE WHEN SUM(CASE WHEN Buy_sell = 1 THEN Trade_Qty ELSE 0 END)>
SUM(CASE WHEN Buy_sell = 2 THEN Trade_Qty ELSE 0 END) THEN 'BF' ELSE 'BT' END ) 
as TradeType,
SUM(CASE WHEN Buy_sell = 2 THEN Trade_Qty * Market_Rate ELSE 0 END) AS SellAmount,
SUM(CASE WHEN Buy_sell = 1 THEN Trade_Qty ELSE 0 END)-
SUM(CASE WHEN Buy_sell = 2 THEN Trade_Qty ELSE 0 END) as NETQTY,
SUM(CASE WHEN Buy_sell = 1 THEN Trade_Qty * Market_Rate ELSE 0 END)-
SUM(CASE WHEN Buy_sell = 2 THEN Trade_Qty * Market_Rate ELSE 0 END)as NetAmt,
SUM(CASE WHEN Buy_sell = 2 THEN Trade_Qty * Market_Rate ELSE 0 END)-
SUM(CASE WHEN Buy_sell = 1 THEN Trade_Qty * Market_Rate ELSE 0 END) as PNLAmt 
FROM tradeFile where Inst_Type='FUTIDX' OR Inst_Type='FUTSTK' 
   and Sauda_Date between convert(datetime,'1 Mar 2013') 
   and convert(datetime,'10 Mar 2013') 
   group by Scrip_Code,convert(datetime,sauda_date) 
   order by convert(varchar(11),sauda_date)

但是我得到的结果是:

请帮助我.

推荐答案

将convert(datetime,sauda_date)更改为datediff(d,0,sauda_date)并按同一列分组

Change convert(datetime,sauda_date) to datediff(d,0,sauda_date) and group by the same column

即

SELECT   datediff(d,0,sauda_date) sauda_date,Scrip_Code,...
group by Scrip_Code,ExpiryDate,datediff(d,0,sauda_date);
