Here are my 2 tables.
Review_master
id Rev_month Rev_year ...
1 JAN 2017
2 MAR 2017
4 FEB 2017
Review_det
Id Rev_id closed_date (MM/DD/YYYY)
1 1 01/01/2017
2 1 02/01/2017
3 1 01/17/2017
4 2 03/03/2017
5 2 04/03/2017
6 4 02/02/2017
6 4 02/05/2017
Now i need to find out number of reviews which are closed outside that month. Review id "1" is of Jan month, and from review details table review_detail_id 2 is closed on feb month, so it should be counted.
Final output:
Rev_Id #_Closed_outside_month
1 1
2 1
4 0
there two main points :
Inequality of literal value of MON for closed date and rev_month
rev_month != to_char(closed_date,'MON')
Combining two tables with outer join.
So, you can easily use the following :
select m.id "Rev_id", count(closed_date) "#_Closed_outside_month"
from Review_det d right outer join Review_master m on ( d.Rev_id = m.id )
and rev_month != to_char(closed_date,'MON')
group by m.id
order by m.id;
D e m o
Here's one option:

I'm trying to return the total number of sales for every month, every quarter, for the year 2016. I want to display annual sales on the first month row, and not on the other rows. Plus, I want to display the quarter sales on the first month of each quarter, and not on the others.
To further explain this, here's what I want to achieve:
MONTH MONTH_SALES QUARTER_SALES YEAR_SALES
1 2183 5917 12505
2 1712 - -
3 1972 - -
4 2230 6588 -
5 2250 - -
6 2108 - -
Here's my SQL query so far:
SELECT
Time.month,
SUM(Sales.sales) AS MONTH_SALES, -- display monthly sales.
CASE
WHEN MOD(Time.month, 3) = 1 THEN ( -- first month of quarter
SELECT
SUM(Sales.sales)
FROM
Sales,
Time
WHERE
Sales.Time_id = Time.Time_id
AND Time.year = 2016
GROUP BY
Time.quarter
FETCH FIRST 1 ROW ONLY
)
END AS QUARTER_SALES,
CASE
WHEN Time.month = 1 THEN ( -- display annual sales.
SELECT
SUM(Sales.sales)
FROM
Sales,
Time
WHERE
Sales.Time_id = Time.Time_id
AND Time.year = 2016
GROUP BY
Time.year
)
END AS YEAR_SALES
FROM
Sales,
Time
WHERE
Sales.Time_id = Time.Time_id
AND Time.year = 2016
GROUP BY
Time.month
ORDER BY
Time.month
I'm almost getting the desired output, but I'm getting the same duplicated 6588 value in quarter sales for the first and fourth month (because I'm fetching the first row that comes from first quarter).
MONTH MONTH_SALES QUARTER_SALES YEAR_SALES
1 2183 6588 12505
2 1712 - -
3 1972 - -
4 2230 6588 -
5 2250 - -
6 2108 - -
I even tried to put WHERE Time.quarter = ((Time.month * 4) / 12) but the month value from the outer query doesn't get passed in the subquery.
Unfortunately I don't have enough experience with CASE WHEN expressions to know how to pass the month row. Any tips would be awesome.
How about this?
Sample data:
SQL> with

21 select 7, 700 from dual union all
22 select 8, 800 from dual union all
23 select 9, 900 from dual
24 ),
Query begins here; it uses sum aggregate in its analytic form; partition by clause says what to compute. row_number, similarly, sorts rows in each quarter/year - it is later used in CASE expression to decide whether to show quarterly/yearly total or not.

I'm working with Oracle and I have a table with a column of type TIMESTAMP. I was wondering how can I extract the records from last 4 weeks of activity on the database, partitioned by week.
Following rows are inserted on week 1
kc 2 04-10-2021
vc 3 06-10-2021
vk 4 07-10-2021
Following rows are inserted on week2

Following rows are inserted on week3
vv 7 19-10-2021

ck 5 14-10-2021
vv 7 19-10-2021

One option is to use to_char function and its iw parameter:

Line #13: I intentionally used "one month" instead of "4 weeks" as I thought (maybe wrongly) that you, actually, want that (you know, "a month has 4 weeks" - not exactly, but close, sometimes not close enough).
If you want 4 weeks, what is that, then? Sysdate minus 28 days (as every week has 7 days)? Then you'd modify line #13 to
where datum >= trunc(sysdate - 4*7)
Or, maybe it is really the last 4 weeks:

last 3 months can be achieved with below where condition but how do i split the launch_date into weekly intervals

With the given data, answer should be team id 123
In your sample data, You have only given 21 days of data instead of 3 months.
You can find out the total number of weeks and their week starting date which can then be compared with your table data to check if an award is won by the team for each week as follows:

I guess that it is a calendar you need, i.e. a table which contains all dates involved. Otherwise, how can you display something that doesn't exist?
This is what you currently have (I'm using only the operation table; add another one yourself):

As there are no rows that belong to 02/06/2019, query can't return anything (you already know that).
Therefore, add a calendar. If you already have that table, fine - use it. If not, create one. It is a hierarchical query which adds level to a certain date. I'm using 01/06/2019 as the starting point, creating 5 days (note the connect by clause).

Probably a better option is to dynamically create a calendar so that it doesn't depend on any hardcoded values, but uses the min(date_operation) to max(date_operation) time span. Here we go:

For each id, I want to flag records for the next 3 days. For any record not within 3 days, it starts with 1 again.

1 Jan 3rd 0 (From Jan 1st, it is within 3 days)
1 Jan 5th 1 (From Jan 1st, it is NOT within 3 days. So flag as 1.
Any record with Jan 6th - Jan 8th will be set to 0)
1 Jan 6th 0 (From Jan 5th, it is within 3 days)
2 Jan 15th 1 (Starting record for id 2)
