我希望将所有演出票数与所有演出的总收入相比较。我已设法计算预订的票数，但其完整查询无效并给我错误。
示例结果将遵循以下示例：
`tickets booked = 9
total revenue of the performance = xxx$
total revenue of all the performances = xxx$
我正在使用的查询是：
SET @performancerevenue = '50 Shades of Grey';
select distinct P.perName as Performance,
(select COUNT(ticketBooked) from bookings as B
inner join performances as P on
B.perID = p.perID where perName = @performancerevenue) as
[Number of Ticket Booked ],
CAST(AVG((T.ticketPrice*left(B.totalCost,1))) over() as decimal(6,2)) as[Total Revenue from the performance (£)],
CAST(AVG(convert(decimal(5,2),(left(PY.totalAmount,1)))) over() as decimal(5,2)) as [Total revenue]
from performances as P
inner join tickets as T
on T.perID = P.perID
inner join bookings as B
on T.bookingID = B.bookingID
inner join payments as PY
where P.perName = @performancerevenue

我一直在努力让结果在过去4小时内正常工作，但它只是给我错误我会非常感谢你的帮助:(
感谢
答案 0 :(得分：0)
在我看来，您可以通过以下方式获得所需的结果：
SELECT DISTINCT
P.perName as [Perf],
SUM(B.ticketBooked) OVER(PARTITION BY P.perName) as [BookedTickets],
SUM(B.totalCost) OVER(PARTITION BY P.perName) as [PerfRevenue],
SUM(B.totalCost) OVER() as [TotalRevenue]
from bookings as B
inner join performances as P on B.perID = p.perID
此查询的结果如下：
------------------------------------------------------------
Perf BookedTickets PerfRevenue TotalRevenue
------------------+---------------+------------+------------
50 Shades of Grey 15 196.00 238.00
Paddington 4 42.00 238.00
您可以为此表添加任何外部查询以进行其他过滤和计算。
