使用子选择外部的表进行SQL子选择查询

Question

I'm trying to retrieve the count the number of times that a teammate has beat his teammate based on DRIVERPOSITION , however i keep getting that invalid select-list in subselect i guess this is because i use the b and a table inside the subselect query?

Sample Data

RACEID  CONSTRUCTORID  DRIVERID  DRIVERPOSITION
970     4              826       3              
970     4              807       7
960     4              826       4              
960     4              807       7
970     3              820       10              
970     3              810       12
960     3              820       13              
960     3              810       11

DESIRED RESULT

RACEID  CONSTRUCTORID  DRIVERID  WINS
970     4              826       2              
970     4              807       0
960     3              820       1              
960     3              810       1

What i tried so far

SELECT 
(
SELECT COUNT(
CASE 
WHEN b.DRIVERPOSITION > a.DRIVERPOSITION THEN 1
ELSE 0 END
)
FROM QUALIFYING b 
WHERE RACEYEAR = to_char(NOW(), 'YYYY')
AND a.CONSTRUCTORID = b.CONSTRUCTORID
AND a.RACEID = b.RACEID
AND a.DRIVERID != b.DRIVERID
)
FROM QUALIFYING a
INNER JOIN RACES 
ON a.RACEID = RACES.RACEID
INNER JOIN DRIVERS
ON a.DRIVERID = DRIVERS.DRIVERID
INNER JOIN CONSTRUCTORS
ON a.CONSTRUCTORID = CONSTRUCTORS.CONSTRUCTORID
WHERE RACEYEAR = to_char(NOW(), 'YYYY');

I think this does what you want:

select raceid, constructorid, driverid,
       sum(case when seqnum = 1 then 1 else 0 end) as numwins
from (select d.*,
             row_number() over (partition by raceid, constructorid order by driverposition) as seqnum
      from data d
     ) d
group by raceid, constructorid;

However, I have no idea how this fits into your query. Your sample data refers to one table. Your query has multiple table references.
