How to report for all rows when joining? - sql

Question

I'd like to report for all batch_runs that meet where batch_run > 200833 and batch_id=100
If a BATCH_RUN does not have any batch_id = 100, then report 0.
select batch_id,
batch_run,
count(*) over (partition by batch_id,
batch_run
order by batch_run) as total_lot_count,
sum(lot_size) over (partition by batch_id,
batch_run) as total_lot_size,
row_number() over (partition by batch_id
order by batch_run) as line_number
from batch_jobs
-- inner join batches on batch_jobs.batch_run = batches.batch_run
-- left join batches on batch_jobs.batch_run = batches.batch_run
where batch_run > 200833
and batch_id = 100

BATCHES
--------------- ----------
BatchSequence Batch_run
--------------- ----------
1 200833
2 200911
3 200922
4 200933
5 201011
6 201022
7 201033
BATCH_RUNS
------------- ---------- ---------
Batch_id Batch_run Lot_size
------------- ---------- ---------
100 200933 10
100 200933 20
100 200933 30
100 201022 400
100 201022 500
Desired result:

Batch_Run Batch_id Lot_count Total_Lots Line_No
--------------- --------- ---------- ----- ---- -------
200911 0 1
200922 100 3 60 2
200933 0 3
201011 0 4
201022 100 2 900 5
201033 0 6

It's too bad that your post has inconsistencies with your SQL Fiddle. It makes it all a bit confusing. But I think that this is what you were looking for. And as you'll see, apart from row_number, analytic functions are not really needed.
select b.batch_run,
bj.batch_id,
count(bj.batch_run) as total_lot_count,
coalesce(sum(bj.lot_size), 0) as total_lot_size,
row_number() over (order by b.batch_sequence) as Line_No
from batches b
left join batch_jobs bj
on bj.batch_run = b.batch_run
and bj.batch_id = 100
where b.batch_run > 200833
group by b.batch_sequence, b.batch_run, bj.batch_id
order by Line_No
