Question

嗨，我正在尝试使以下逻辑正常工作。但它说不是按功能分组。.不知道为什么..我想获取两个表中的记录，然后将每个表的收入相加以在第一选择中累计总收入。

select ob_location_id, 
ib_location_id, 
vehicle_class, 
return_date,
RENTAL_DATE,
sum(revenue) as TotalRevenue
from
(select ob_location_id, 
ib_location_id, 
vehicle_class, 
return_date,
RENTAL_DATE,
SUM(DEMAND_TO_COME * BOARD_RATE) AS revenue
from PA_FCS_BLEND_FINAL) a 
Union all 
Select 
ob_location_id, 
ib_location_id, 
vehicle_class, 
return_date,
RENTAL_DATE,
sum(MATERIALIZED_BOH_REVENUE) as revenue
from PA_FCS_BLEND_BOH

group by 
ob_location_id, 
ib_location_id, 
vehicle_class, 
return_date,
RENTAL_DATE,
totalRevenue;

Answer 1

a内联视图缺少GROUP BY子句
最后的GROUP BY不应包含TOTAL_REVENUE

一个 dummy 示例（日期类型当然不匹配，但请不要在意）：

SQL> CREATE TABLE pa_fcs_blend_final
  2  (
  3     ob_location_id  NUMBER,
  4     ib_location_id  NUMBER,
  5     vehicle_class   NUMBER,
  6     return_date     NUMBER,
  7     rental_date     NUMBER,
  8     demand_to_come  NUMBER,
  9     board_rate      NUMBER
 10  );

Table created.

SQL> insert into pa_fcs_blend_final values
  2  (1, 2, 3, 4, 5, 6, 7);

1 row created.

SQL> CREATE TABLE pa_fcs_blend_boh
  2  (
  3     ob_location_id            NUMBER,
  4     ib_location_id            NUMBER,
  5     vehicle_class             NUMBER,
  6     return_date               NUMBER,
  7     rental_date               NUMBER,
  8     materialized_boh_revenue  NUMBER
  9  );

Table created.

SQL> insert into pa_fcs_blend_boh values
  2  (1, 2, 3, 4, 5, 6);

1 row created.

查询返回某物；这是对的吗？不知道。

SQL>   SELECT ob_location_id,
  2           ib_location_id,
  3           vehicle_class,
  4           return_date,
  5           rental_date,
  6           SUM (revenue) AS totalrevenue
  7      FROM (  SELECT ob_location_id,
  8                     ib_location_id,
  9                     vehicle_class,
 10                     return_date,
 11                     rental_date,
 12                     SUM (demand_to_come * board_rate) AS revenue
 13                FROM pa_fcs_blend_final
 14            GROUP BY ob_location_id,                         --> this is missing
 15                     ib_location_id,
 16                     vehicle_class,
 17                     return_date,
 18                     rental_date) a
 19  GROUP BY ob_location_id,
 20           ib_location_id,
 21           vehicle_class,
 22           return_date,
 23           rental_date
 24  UNION ALL
 25    SELECT ob_location_id,
 26           ib_location_id,
 27           vehicle_class,
 28           return_date,
 29           rental_date,
 30           SUM (materialized_boh_revenue) AS revenue
 31      FROM pa_fcs_blend_boh
 32  GROUP BY ob_location_id,
 33           ib_location_id,
 34           vehicle_class,
 35           return_date,
 36           rental_date  --> total_revenue (you had) shouldn't be here
 37  /
