Select TOP or GROUP BY ranked data from nested SQL query - sql

Question

I have a table with events and results and query like this:
SELECT T2.EventDate, T2.EventPlace, T2.Par1,
T2.Par2, T2.Result, T2.ResultEventDate_sum
FROM
(SELECT TOP 15 EventDate, EventPlace, Par1, Par2,
Result, SUM(Result) OVER (PARTITION BY EventDate) AS ResultEventDate_SUM
FROM
(SELECT EventDate, EventPlace, Par1, Par2, Result,
ROW_NUMBER() OVER (PARTITION BY EventDate ORDER BY Result DESC) AS EventDate_rank
FROM MainTable
WHERE AND CAST(UserNb AS int) = 103
AND Col1 = 'X' AND Result > 0 AND Col2 LIKE '%Y%'
AND Par1 > 500 AND Par1 <= 700) ranked
WHERE EventDate_rank <= 5 ORDER BY ResultEventDate_sum DESC) T2
The results I get:
EventDate EventPlace Par1 Par2 Result ResultEventDate_SUM
2019-05-26 PLACE nb 1 508 604 51.20 278.11
2019-05-26 PLACE nb 1 508 571 51.68 278.11
2019-05-26 PLACE nb 1 508 249 56.38 278.11
2019-05-26 PLACE nb 1 508 42 59.40 278.11
2019-05-26 PLACE nb 1 508 39 59.45 278.11
2019-06-09 PLACE nb 3 508 449 50.95 217.05
2019-06-09 PLACE nb 3 508 259 54.79 217.05
2019-06-09 PLACE nb 3 508 254 54.89 217.05
2019-06-09 PLACE nb 3 508 178 56.42 217.05
2019-06-16 PLACE nb 4 508 372 51.49 169.56
2019-06-16 PLACE nb 4 508 66 58.51 169.56
2019-06-16 PLACE nb 4 508 20 59.56 169.56
2019-06-02 PLACE nb 2 508 533 50.19 107.46
2019-06-02 PLACE nb 2 508 149 57.27 107.46
I need to get list of best (highest) sum of max 5 result from each event, but take only 3 best events. So I put SELECT TOP 15 (3 events by 5 results) and the query results is ok when there is a 5 results by each event. But if there is less then 5 results for each event I get also records from 4 event. How to modify query to be sure there will be only 3 events no matter how many results are for each one? In this example cut last 2 records (1 event with the smallest result 107.46). Is there a way to achieve this by simplify query without adding another code?
I tried to put COUNT(*) in the first line, but it counts the same like col resulteventdate, so I cannot use it as condition. Also If I added for ex. EXISTS, the statement is too big and take to much time.
Expected results is a table with only 3 events with best ResultEventDate_sum:
EventDate EventPlace Par1 Par2 Result ResultEventDate_SUM
2019-05-26 PLACE nb 1 508 604 51.20 278.11
2019-05-26 PLACE nb 1 508 571 51.68 278.11
2019-05-26 PLACE nb 1 508 249 56.38 278.11
2019-05-26 PLACE nb 1 508 42 59.40 278.11
2019-05-26 PLACE nb 1 508 39 59.45 278.11
2019-06-09 PLACE nb 3 508 449 50.95 217.05
2019-06-09 PLACE nb 3 508 259 54.79 217.05
2019-06-09 PLACE nb 3 508 254 54.89 217.05
2019-06-09 PLACE nb 3 508 178 56.42 217.05
2019-06-16 PLACE nb 4 508 372 51.49 169.56
2019-06-16 PLACE nb 4 508 66 58.51 169.56
2019-06-16 PLACE nb 4 508 20 59.56 169.56
Thanks in advance for any tips.
UPDATE after tests:
Thanks to all of you. I tested your propositions in the query and Dense_Rank do the job correctly and quite fast. Helped me a lot.

Answer 1

You need to use one more window function i.e. Dense_Rank.
This may help you get required output.
select EventDate,EventPlace,Par1,Par2,Result,ResultEventDate_sum from(
SELECT T2.EventDate, T2.EventPlace, T2.Par1,
T2.Par2, T2.Result, T2.ResultEventDate_sum ,
DENSE_RANK()over(order by ResultEventDate_sum,T2.EventDate desc)rnk
FROM
(SELECT EventDate, EventPlace, Par1, Par2,
Result, SUM(Result) OVER (PARTITION BY EventDate) AS ResultEventDate_SUM
FROM
(SELECT EventDate, EventPlace, Par1, Par2, Result,
ROW_NUMBER() OVER (PARTITION BY EventDate ORDER BY Result DESC) AS
EventDate_rank
FROM MainTable
WHERE AND CAST(UserNb AS int) = 103
AND Col1 = 'X' AND Result > 0 AND Col2 LIKE '%Y%'
AND Par1 > 500 AND Par1 <= 700) ranked
WHERE EventDate_rank <= 5 ) T2
)T1
WHERE RNK<=3

Answer 2

In this following query, I have considered EventPlace as Event_ID. This query will return TOP 3 Event (Based on SUM of Result per Event) Details (TOP 5 Rows for each Event)
SELECT * FROM
(
SELECT *, ROW_NUMBER() OVER(PARTITION BY EventPlace ORDER BY EventPlace,Result DESC) RN
FROM your_table
WHERE EventPlace IN
(
-- You can set any number based on
-- How many event details you wants to see
SELECT TOP 3 EventPlace
FROM
(
SELECT *, ROW_NUMBER() OVER(PARTITION BY EventPlace ORDER BY EventPlace,Result DESC) RN
FROM your_table
)A
-- You can set any number based on
-- How many row's result you want to SUM for checking
WHERE RN <= 5
GROUP BY EventPlace
ORDER BY SUM(Result) DESC
)
)B
WHERE RN <= 5
