“不是单组分组功能”

Question

Hi I am trying to get the below logic working. but it says Not a single-group by function.. not sure why..I want to get records that are in both table and add the revenue of each to accumulate total revenue in the first select.

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

• The a inline view is missing the GROUP BY clause
• the final GROUP BY shouldn't contain TOTAL_REVENUE

A dummy example (datetypes certainly don't match, but never mind that):

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.

Query which returns something ; is it correct? No idea.

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  /
