Question

我使用了以下查询

SELECT 
    a.cluster_cd,
    (SELECT
         Sum(BALANCE_AREA) 
     FROM 
         AGRI.plantation_TRAN p 
     WHERE 
         p.plot_cluster_cd = a.cluster_cd 
         AND trunc(a.agreement_date) = trunc(sysdate) 
         AND a.PLOT_NO = p.PLOT_NO 
         AND a.SEASON_CD = p.SEASON_CD 
         AND (a.SEASON_CD = 10)) as Today,
   (SELECT
        Sum(BALANCE_AREA) 
    FROM 
        AGRI.plantation_TRAN p 
    WHERE 
        p.plot_cluster_cd = a.cluster_cd 
        AND trunc(a.agreement_date) BETWEEN to_date('2014-10-24','YYYY-MM-DD') AND trunc(sysdate) 
        AND a.PLOT_NO = p.PLOT_NO 
        AND a.SEASON_CD = p.SEASON_CD 
        AND (a.SEASON_CD=10)) as Todate
FROM
    AGRI.agreement_TRAN a

我得到了

cluster_cd       Today      Todate
 1               0.8         3.5
 1               2.6         8.2
 2               8.3         9.5
 3               0.2         2.6
 2               6.1         9.1
 3               9.8        11.0

但我需要的是

今天和todate字段应该总结为不同的cluster_cd，如

 Cluster_CD        Today      Todate
   1                123         456
   2                125         789
   3                 45         458
   4                456         789

应该在唯一的cluster_cd

上进行求和

Answer 1

你可以试试这个：

Select cluster_cd,sum(today),sum(Todate) from(

SELECT a.cluster_cd,
(select Sum(BALANCE_AREA) 
FROM AGRI.plantation_TRAN p 
where p.plot_cluster_cd=a.cluster_cd and trunc(a.agreement_date)=trunc(sysdate) and a.PLOT_NO =         p.PLOT_NO AND a.SEASON_CD = p.SEASON_CD AND (a.SEASON_CD=10)) as Today,

(select Sum(BALANCE_AREA) 
FROM AGRI.plantation_TRAN p 
where p.plot_cluster_cd=a.cluster_cd and trunc(a.agreement_date) between to_date('2014-10-
24','YYYY-MM-DD') and trunc(sysdate) and a.PLOT_NO = p.PLOT_NO AND a.SEASON_CD = p.SEASON_CD AND      (a.SEASON_CD=10)) as Todate

from AGRI.agreement_TRAN a)t

group by cluster_cd

Answer 2

此查询可能有所帮助：

SELECT a.cluster_cd,
       sum(case when a.agreement_date >= trunc(sysdate) then nvl(BALANCE_AREA, 0) else 0 end) as Today,
       sum(case when a.agreement_date < trunc(sysdate) then nvl(BALANCE_AREA, 0) else 0 end) as Todate
FROM AGRI.agreement_TRAN a
     LEFT JOIN AGRI.plantation_TRAN p
     ON (p.plot_cluster_cd = a.cluster_cd
         and a.PLOT_NO = p.PLOT_NO 
         and a.SEASON_CD = p.SEASON_CD
        )
WHERE a.agreement_date between to_date('2014-10-24000000','YYYY-MM-DDHH24MISS') 
                           and trunc(sysdate)+1-1/24/60/60
  AND a.SEASON_CD=10
GROUP BY a.cluster_cd;

Oracle子查询从多个表中检索数据？
