How do I edit the code that calculates the value for the four weeks of the month for all months with pl/sql? - sql

I divided the month into four weeks and printed the amount for each week. How do I set this up with a loop for 12 months?
declare
cursor c is
select varis_tar, tutar
from muhasebe.doviz_takip
where trunc(varis_tar) BETWEEN TO_DATE('01/10/2021', 'DD/MM/YYYY') AND
TO_DATE('31/10/2021', 'DD/MM/YYYY')
group by varis_tar,tutar;
tutar1 number(13,2):=0;
tutar2 number(13,2):=0;
tutar3 number(13,2):=0;
tutar4 number(13,2):=0;
begin
for r in c loop
if r.varis_tar between TO_DATE('01/10/2021', 'DD/MM/YYYY') AND
TO_DATE('07/10/2021', 'DD/MM/YYYY') then
tutar1:=(r.tutar)+tutar1;
--message(r.tutar);
elsif r.varis_tar between TO_DATE('07/10/2021', 'DD/MM/YYYY') AND
TO_DATE('14/10/2021', 'DD/MM/YYYY') then
tutar2:=(r.tutar)+tutar2;
--message(r.tutar);
elsif r.varis_tar between TO_DATE('14/10/2021', 'DD/MM/YYYY') AND
TO_DATE('21/10/2021', 'DD/MM/YYYY') then
tutar3:=(r.tutar)+tutar3;
--message(r.tutar);
elsif r.varis_tar between TO_DATE('21/10/2021', 'DD/MM/YYYY') AND
TO_DATE('31/10/2021', 'DD/MM/YYYY') then
tutar4:=(r.tutar)+tutar4;
--message(r.tutar);
end if;
end loop;
I tried to get the dates the same way for all the months. I tried that, but it worked wrong.
where trunc(varis_tar) BETWEEN TO_DATE('1', 'DD') AND
TO_DATE('31', 'DD')
if r.varis_tar between TO_DATE('1', 'DD') AND
TO_DATE('07', 'DD') then
elsif r.varis_tar between TO_DATE('7', 'DD') AND
TO_DATE('14', 'DD') then
elsif r.varis_tar between TO_DATE('14', 'DD') AND
TO_DATE('21', 'DD') then
elsif r.varis_tar between TO_DATE('21', 'DD') AND
TO_DATE('31', 'DD') then


I don't know if I'am understanding it correctly but:
try if extract(day from varis_tar) between 1 and 7
or more complex
l_week := to_char(varis_tar,'W'); --week number
if l_week = 1 then --first week
elsif l_week = 2 etc...


Your code has several issues:
date in Oracle is actually a datetime, so between will not count any time after the midnight of the upper boundary.
you count the midnight of the week's end twice: in current week and in the next week (between includes both boundaries).
you do not need any PL/SQL and especially a cursor loop, because it occupy resources during calculation outside of SQL context.
Use datetime format to calculate weeks, because it is easy to read and understand. Then group by corresponding components.

How to resample pandas to hydrologic year (Sep 1 - Aug 31)

I'd like to analyze some daily data by hydrologic year: From 1 September to 31 August. I've created a synthetic data set with:
import pandas as pd
t = pd.date_range(start='2015-01-01', freq='D', end='2021-09-03')
df = pd.DataFrame(index = t)
df['hydro_year'] = df.index.year
df['hydro_year'].loc[df.index.month >= 9] += 1
df['id'] = df['hydro_year'] - df.index.year[0]
df['count'] = 1
Note that in reality I do not have a hydro_year column so I do not use groupby. I would expect the following to resample by hydrologic year:
print(df['2015-09-01':].resample('12M').agg({'hydro_year':'mean','id':'mean','count':'sum'}))
But the output does not align:
| | hydro_year | id | count |
|---------------------+------------+---------+-------|
| 2015-09-30 00:00:00 | 2016 | 1 | 30 |
| 2016-09-30 00:00:00 | 2016.08 | 1.08197 | 366 |
| 2017-09-30 00:00:00 | 2017.08 | 2.08219 | 365 |
| 2018-09-30 00:00:00 | 2018.08 | 3.08219 | 365 |
| 2019-09-30 00:00:00 | 2019.08 | 4.08219 | 365 |
| 2020-09-30 00:00:00 | 2020.08 | 5.08197 | 366 |
| 2021-09-30 00:00:00 | 2021.01 | 6.00888 | 338 |
However, if I start a day earlier, then things do align, except the first day is 'early' and dangling alone...
| | hydro_year | id | count |
|---------------------+------------+----+-------|
| 2015-08-31 00:00:00 | 2015 | 0 | 1 |
| 2016-08-31 00:00:00 | 2016 | 1 | 366 |
| 2017-08-31 00:00:00 | 2017 | 2 | 365 |
| 2018-08-31 00:00:00 | 2018 | 3 | 365 |
| 2019-08-31 00:00:00 | 2019 | 4 | 365 |
| 2020-08-31 00:00:00 | 2020 | 5 | 366 |
| 2021-08-31 00:00:00 | 2021 | 6 | 365 |
| 2022-08-31 00:00:00 | 2022 | 7 | 3 |

IIUC, you can use 12MS (Start) instead of 12M:
>>> df['2015-09-01':].resample('12MS') \
.agg({'hydro_year':'mean','id':'mean','count':'sum'})
hydro_year id count
2015-09-01 2016.0 1.0 366
2016-09-01 2017.0 2.0 365
2017-09-01 2018.0 3.0 365
2018-09-01 2019.0 4.0 365
2019-09-01 2020.0 5.0 366
2020-09-01 2021.0 6.0 365
2021-09-01 2022.0 7.0 3

We can try with Anchored Offsets annually starting with SEP:
resampled_df = df['2015-09-01':].resample('AS-SEP').agg({
'hydro_year': 'mean', 'id': 'mean', 'count': 'sum'
})
hydro_year id count
2015-09-01 2016.0 1.0 366
2016-09-01 2017.0 2.0 365
2017-09-01 2018.0 3.0 365
2018-09-01 2019.0 4.0 365
2019-09-01 2020.0 5.0 366
2020-09-01 2021.0 6.0 365
2021-09-01 2022.0 7.0 3

SQL query for setting column based on last seven entries

Problem
I am having trouble figuring out how to create a query that can tell if any userentry is preceded by 7 days without any activity (secondsPlayed == 0) and if so, then indicate it with the value of 1, otherwise 0.
This also means that if the user has less than 7 entries, the value will be 0 across all entries.

Thoughts
At first I was thinking about using the Lag function with a 7 offset, but this would obviously not relate to any of the subjects in between.
I was also thinking about creating a rolling window/average for a period of 7 days and evaluating if this is above 0. However this might be a bit above my skill level.
Any chance anyone has a good solution to this problem.

Assuming that you have data every day (which seems like a reasonable assumption), you can sum a window function:
select t.*,
(case when sum(secondsplayed) over (partition by userid
order by estimationdate
rows between 6 preceding and current row
) = 0 and
row_number() over (partition by userid order by estimationdate) >= 7
then 1
else 0
end) as inactive
from t;
In addition to no holes in the dates, this also assumes that secondsplayed is never negative. (Negative values can easily be incorporated into the logic, but that seems unnecessary.)

In my experience this type of input tables do not consist of inactivity entries and usually look like this (only activity entries are present here)
Input table:
+------------------------------+-------------------------+---------------+
| userid | estimationDate | secondsPlayed |
+------------------------------+-------------------------+---------------+
| a | 2016-07-14 00:00:00 UTC | 192.5 |
| a | 2016-07-15 00:00:00 UTC | 357.3 |
| ---------------------------- | ---------------------- | ---- |
| b | 2016-07-02 00:00:00 UTC | 31.2 |
| b | 2016-07-03 00:00:00 UTC | 42.1 |
| b | 2016-07-04 00:00:00 UTC | 41.9 |
| b | 2016-07-05 00:00:00 UTC | 43.2 |
| b | 2016-07-06 00:00:00 UTC | 91.5 |

Populating actual dates in recursive function

I am trying to create a table which contains Fiscal day,month and year.
However I want to add an actual date column in the give result as well.
My Query -
(FISCAL_DAY, BEGIN_DATE ,END_DATE ,FISCAL_MONTH,FISCAL_QUARTER,FISCAL_YEAR ) AS
(SELECT CAST(1 AS INT) ,begin_date,end_DATE,FISCAL_MONTH,FISCAL_QUARTER,FISCAL_YEAR FROM DB_NAME.ORIGINAL_FISCAL_TABLE
UNION ALL
SEL Fiscal_Day+1,begin_date,end_DATE,FISCAL_MONTH,FISCAL_QUARTER,FISCAL_YEAR
FROM TMP_FISCAL_DAY WHERE BEGIN_DATE<END_DATE AND FISCAL_DAY<END_DATE-BEGIN_DATE)
SEL * FROM TMP_FISCAL_DAY
Output

How do I put date in recursion such that actual dates show up ?
My Attempt (incorrect results)
WITH RECURSIVE TMP_FISCAL_DAY
(FISCAL_DAY, ACTUAL_DATE, BEGIN_DATE ,END_DATE ,FISCAL_MONTH,FISCAL_QUARTER,FISCAL_YEAR ) AS
(SELECT CAST(1 AS INT) ,cast(current_date as date), begin_date,end_DATE,FISCAL_MONTH,FISCAL_QUARTER,FISCAL_YEAR FROM DB_NAME.ORIGINAL_FISCAL_TABLE
UNION ALL
SEL Fiscal_Day+1,ACTUAL_DATE+FISCAL_DAY,begin_date,end_DATE,FISCAL_MONTH,FISCAL_QUARTER,FISCAL_YEAR
FROM TMP_FISCAL_DAY WHERE BEGIN_DATE<END_DATE AND FISCAL_DAY<END_DATE-BEGIN_DATE)
SEL * FROM TMP_FISCAL_DAY where CURRENT_DATE BETWEEN BEGIN_DATE AND END_DATE

Assuming there's one row per fiscal month in your ORIGINAL_FISCAL_TABLE you should filter the current month before recursion and then use BEGIN_DATE instead of CURRENT_DATE:
WITH RECURSIVE TMP_FISCAL_DAY ( FISCAL_DAY, ACTUAL_DATE, BEGIN_DATE ,END_DATE ,FISCAL_MONTH,FISCAL_QUARTER,FISCAL_YEAR )
AS
(
SELECT
Cast(1 AS INT)
,BEGIN_DATE
,begin_date
,end_DATE
,FISCAL_MONTH
,FISCAL_QUARTER
,FISCAL_YEAR
FROM DB_NAME.ORIGINAL_FISCAL_TABLE
WHERE Current_Date BETWEEN BEGIN_DATE AND END_DATE
UNION ALL
SELECT
Fiscal_Day+1
,ACTUAL_DATE+1
,begin_date
,end_DATE
,FISCAL_MONTH
,FISCAL_QUARTER
,FISCAL_YEAR
FROM TMP_FISCAL_DAY
WHERE ACTUAL_DATE+1 < END_DATE
)
SELECT *
FROM TMP_FISCAL_DAY
As #RonBallard wrote there's no need for recursion, you can use EXPAND ON instead:
SELECT
ACTUAL_DATE - BEGIN_DATE + 1 AS Fiscal_Day, dt.*
FROM
(
SELECT Begin(pd) AS ACTUAL_DATE, t.*
FROM ORIGINAL_FISCAL_TABLE AS t
WHERE Current_Date BETWEEN BEGIN_DATE AND END_DATE
EXPAND ON PERIOD(BEGIN_DATE, END_DATE) AS pd
) AS dt
But finally there should be no need for any kind of calculation, every company should have a calendar table with pre-calculated data:
SELECT ...
FROM myCalendar
WHERE Current_Date BETWEEN FISCAL_MONTH_BEGIN_DATE AND FISCAL_MONTH_END_DATE

I need a query to group an aggregate in one table by date ranges in another table.

select accountid, weekstart, weekend,

from table2
inner join table1 on table2.rdate >= table1.weekstart and table2.rdate < table1.weekend
group by accountid, weekstart, weekend;

weekend for week 18 should be 2016-02-07, because 2016-02-08 is weekstart for week 19.

Average daily peak hours in a week with SQL select

I'm trying to list the weekly average of customers in different restaurants in their daily peak hours, for example:
Week | Day | Hour | Rest | Custom
20 | Mon | 08-12 | KFC | 15
20 | Mon | 12-16 | KFC | 10
20 | Mon | 16-20 | KFC | 8
20 | Tue | 08-12 | KFC | 20
20 | Tue | 12-16 | KFC | 11
20 | Tue | 16-20 | KFC | 9
20 | Mon | 08-12 | MCD | 13
20 | Mon | 12-16 | MCD | 14
20 | Mon | 16-20 | MCD | 19
20 | Tue | 08-12 | MCD | 31
20 | Tue | 12-16 | MCD | 20
20 | Tue | 16-20 | MCD | 22
20 | Mon | 08-12 | PHT | 15
20 | Mon | 12-16 | PHT | 12
20 | Mon | 16-20 | PHT | 11
20 | Tue | 08-12 | PHT | 08
20 | Tue | 12-16 | PHT | 07
20 | Tue | 16-20 | PHT | 14
The desired result should be:
WeeK | Rest | Custom
20 | KFC | 17.5
20 | MCD | 25
20 | PHT | 14.5
Is it possible to do it in one line of SQL?

This is really two steps. Get the maximum people per day per restaurant and then average that per week:
select week, rest, sum(maxc)
from (select Week, Day, Rest, max(Custom) as maxc
from t
group by Week, Day, Rest
) wdr
group by week, rest;
