MS SQL-多个运行总计，每个总计基于不同的GROUP BY

Question

Need to generate the 2 running total columns which are each based on a different group-by. I would PREFER that the solution use the OUTER APPLY method like the one below, except modified to run multiple running totals/sums on different group bys/columns. See image for example of desired result

SELECT t1.LicenseNumber, t1.IncidentDate, t1.TicketAmount, 
  RunningTotal = SUM(t2.TicketAmount)
FROM dbo.SpeedingTickets AS t1
OUTER APPLY
(
  SELECT TicketAmount 
    FROM dbo.SpeedingTickets 
    WHERE LicenseNumber = t1.LicenseNumber
    AND IncidentDate <= t1.IncidentDate
) AS t2
GROUP BY t1.LicenseNumber, t1.IncidentDate, t1.TicketAmount
ORDER BY t1.LicenseNumber, t1.IncidentDate;

Answer 1

Use outer apply twice:

Here is how you get one running total:

SELECT st.*, r1.RunningTotal
FROM dbo.SpeedingTickets st OUTER APPLY
     (SELECT SUM(st2.TicketAmount) as RunningTotal
      FROM dbo.SpeedingTickets st2
      WHERE st2.LicenseNumber = st.LicenseNumber AND
            st2.IncidentDate <= st.IncidentDate
     ) r1
ORDER BY st.LicenseNumber, st.IncidentDate;

For two, you just add another OUTER APPLY . Your question doesn't specify what the second aggregation is, and the linked picture has no relevance to the description in the question.

Notes:

• The aggregation goes in the subquery, not in the outer query.
• Use table abbreviations for table aliases. Such consistency makes it easier to follow the query.
• When using correlated subqueries, always use qualified column names for all columns.
