sql - Window over query not retrieving what I need

We are trying to create a query to do an aggregation on the data below. This is a skinny table, with log data for operations happening in a set of equipment. The equipment is identified in the "ID" column. In this sample, there are two equipment. We need to total the column "Value" based on the label in column "Label_2". The aggregation starts from the latest "Ct-Primary" label, and ends when it finds the label 'Out Track'. So for equipment "C409EA83-A2C6-39F5-A8BC-C9E91BA7A756" it would start aggregating at Time "5/2/2023 14:30" and end at time "5/5/2023 6:00" and then again from time "5/9/2023 0:00" and ends at "5/11/2023 18:00." It would do the same for the rest of the equipment ID in the list.So the result I expect for this data sample would be:

ID   Total
C409EA83-A2C6-39F5-A8BC-C9E91BA7A756 153.00
97B398D7-9BBC-D036-1CC2-C828F0F22243 118.50

So far I have tried a few things with the over function, but that only picks by the ID and aggregates all the values in that ID. I tried adding an over by ID and one of the labels and it gives me the total value for "Ct-Primary" only but not the window I want to aggregate. Sample:

Syntax is in SQL Server as I dont have trino to test.

I have broken down it into two CTEs.

label CTE ranks the valid labels ct-primary,out track for each id.

label CTE outputs

select id,time,label_2,
    row_number() over (partition by id order by time) as rn
    from log   
    where label_2 in ('ct-primary', 'out track')

id	time	label_2	rank
97B398D7-9BBC-D036-1CC2-C828F0F22243	2023-05-02 21:00:00.000	Ct-Primary	1
97B398D7-9BBC-D036-1CC2-C828F0F22243	2023-05-09 00:00:00.000	Out Track	2
C409EA83-A2C6-39F5-A8BC-C9E91BA7A756	2023-05-02 12:45:00.000	Ct-Primary	1
C409EA83-A2C6-39F5-A8BC-C9E91BA7A756	2023-05-02 14:30:00.000	Ct-Primary	2
C409EA83-A2C6-39F5-A8BC-C9E91BA7A756	2023-05-05 06:00:00.000	Out Track	3
C409EA83-A2C6-39F5-A8BC-C9E91BA7A756	2023-05-09 00:00:00.000	Ct-Primary	4
C409EA83-A2C6-39F5-A8BC-C9E91BA7A756	2023-05-11 18:00:00.000	Out Track	5

Next is valid_pairs CTE which SELF JOINS where the label starts with latest ct-primary and ends with out track and there would be a difference of 1 in the rank between the consecutive records, so it would return something like this

id	start_time	end_time
97B398D7-9BBC-D036-1CC2-C828F0F22243	2023-05-02 21:00:00.000	2023-05-09 00:00:00.000
C409EA83-A2C6-39F5-A8BC-C9E91BA7A756	2023-05-02 14:30:00.000	2023-05-05 06:00:00.000
C409EA83-A2C6-39F5-A8BC-C9E91BA7A756	2023-05-09 00:00:00.000	2023-05-11 18:00:00.000

Finally the valid_pairs CTE is joined with the log table based on id and the time between valid pairs's start_time and end_time and calculate the aggregated value grouped by id

select  l.id,sum(l.value) as total
from log l
inner join valid_pairs vp
on l.id = vp.id and l.time between vp.start_time and vp.end_time
group by l.id

Final Query :

Demo Fiddle

with labels as (
    select id,time,label_2,
    row_number() over (partition by id order by time) as rank
    from log   
    where label_2 in ('ct-primary', 'out track')
),
valid_pairs as
(
    select  l1.id, l1.time as start_time, l2.time as end_time
    from labels l1
    inner join  labels l2 on l1.id = l2.id and l2.rank = l1.rank + 1
    where l1.label_2 = 'ct-primary' and l2.label_2 = 'out track'
)
select  l.id,sum(l.value) as total
from log l
inner join valid_pairs vp
on l.id = vp.id and l.time between vp.start_time and vp.end_time
group by l.id
order by  l.id;

Output

id	total
97B398D7-9BBC-D036-1CC2-C828F0F22243	118.5

You can generate a counter over the set by running backward so that every Out Track defines the start of a new block. Then within each block you seek the Ct-Primary labels in order to rope off the desired sub-block of values to keep. When looking in reverse you'll always be grabbing the first one and discarding the rest.

You do have to do an adjustment so that Ct-Primary will become the last row rather then the first row of the new sub-block. A lagged value or a window frame could handle this but I just used a simple case expression that checks whether the current label is Ct-Primary to deduct one.

In the end you just use those generated (sub)block numbers to filter out the rows you don't want:

with b1 as (
    select *,
        count(case when Label_2 = 'Out Track' then 1 end)
            over (partition by ID order by "Time" desc) as block1
    from T
), b2 as (
    select *,
        count(case when Label_2 = 'Ct-Primary' then 1 end)
            over (partition by ID, block1 order by "Time" desc)
            + case when Label_2 = 'Ct-Primary' then -1 else 0 end + 1 as block2
    from b1
)
select ID, sum(Value)
from b2
where block1 >= 1 and block2 = 1
group by ID;

https://dbfiddle.uk/fwlmAskB?hide=2

(This does assume there won't be multiple Out Track labels between successive Ct-Primary labels.)

If the values are all positive, here's another approach that uses running sums to derive the desired sum:

with b as (
    select *,
        count(case when Label_2 = 'Out Track' then 1 end)
            over (partition by ID order by "Time" desc) as blk,
        sum(Value)
            over (partition by ID order by "Time" desc) as rs
    from T
), s as (
    select ID,
        min(case when Label_2 = 'Ct-Primary' then rs end) - min(rs - value) as s
    from b
    where blk >= 1
    group by ID, blk
)
select ID, sum(s)
from s
group by ID;

I suggest use running sum (total) of value.

Id	Label_2	Value	runningTotal	groupValue
A	~~NU/ND~~	3	3
A	Ct-Primary	10	13
A	~~Safety Mtg~~	5	18
A	Out Track	22	40	(40-13+10)=37=(10+5+22)

In this solution, I like that only one sorting (or covering index (id,time)include(Label2,value)) is needed. All window functions use (partition by id order by time)

Subquery a calculate running sum.
Subquery b takes only rows with Label_2 in('Ct-Primary','Out Track') and calculate groupValue for rows with (Label_2='Out Track') as

(+) score (running sum) for current row (Label_2='Out Track')
(-) score of previous row (Label_2='Ct-Primary')
(+) value of previous row (Label_2='Ct-Primary')

See example

select id
  ,sum(groupValue)  tot
from(
  select *
    ,lag(Label_2)over(partition by id order by time)prevLabel_2
    ,score -lag(score,1,0)over(partition by id order by time)
     +lag(value,1,0)over(partition by id order by time)groupValue
  from(
     select * ,sum(value)over(partition by id order by time)score
     from log
  ) a
  where Label_2 in('Ct-Primary','Out Track')
)b
where Label_2='Out Track' and prevLabel_2='Ct-Primary'
group by id

Before filter where Label_2='Out Track' and prevLabel_2='Ct-Primary' and grouping

  select *
    ,lag(Label_2)over(partition by id order by time)prevLabel_2
    ,score -lag(score,1,0)over(partition by id order by time)
     +lag(value,1,0)over(partition by id order by time)groupValue
  from(
     select * ,sum(value)over(partition by id order by time)score
     from log
  ) a
  where Label_2 in('Ct-Primary','Out Track')
