Hi I have a table with date and the number of views that we had in our channel at the same day
date views
03/06/2020 5
08/06/2020 49
09/06/2020 50
10/06/2020 1
13/06/2020 1
16/06/2020 1
17/06/2020 102
23/06/2020 97
29/06/2020 98
07/07/2020 2
08/07/2020 198
12/07/2020 1
14/07/2020 168
23/07/2020 292
No we want to see in each calendar date the sum of the past 7 and 30 days
so the result will be
date sum_of_7d sum_of_30d
01/06/2020 0 0
02/06/2020 0 0
03/06/2020 5 5
04/06/2020 5 5
05/06/2020 5 5
06/06/2020 5 5
07/06/2020 5 5
08/06/2020 54 54
09/06/2020 104 104
10/06/2020 100 105
11/06/2020 100 105
12/06/2020 100 105
13/06/2020 101 106
14/06/2020 101 106
15/06/2020 52 106
16/06/2020 53 107
17/06/2020 105 209
18/06/2020 105 209
so I was wondering what is the best SQL that I can write in order to get it
I'm working on redshift and the actual table (not this example) include over 40B rows
I used to do something like this:
select dates_helper.date
, tbl1.cnt
, sum(tbl1.cnt) over (order by date rows between 7 preceding and current row ) as sum_7d
, sum(tbl1.cnt) over (order by date rows between 30 preceding and current row ) as sum_7d
from bi_db.dates_helper
left join tbl1
on tbl1.invite_date = dates_helper.date
This is a sample Data Frame

I am running this query
%sql
use my_items_table;
select weekofyear(Date), count(items_sold) as Sum
from my_items_table
where year(Date)=2020
group by weekofyear(Date)
order by weekofyear(Date)
I am getting this output. (IMP: I have added random values in Sum)
Week Sum
1 | 300091
2 | 312756
3 | 309363
4 | 307312
5 | 310985
6 | 296889
7 | 315611
But I want in which with week number one column should hold a start date of each week. Like this
Start_Date Week Sum
12/29/2019 1 300091
1/5/2020 2 312756
1/12/2020 3 309363
1/19/2020 4 307312
1/26/2020 5 310985
2/2/2020 6 296889
2/9/2020 7 315611
I am running the query on Azure Data Bricks.
If you have data for all days, then just use min():
select min(date), weekofyear(Date), count(items_sold) as Sum
from my_items_table
where year(Date) = 2020
group by weekofyear(Date)
order by weekofyear(Date);
Note: The year() is the calendar year starting on Jan 1. You are not going to get dates from other years using this query. If that is an issue, I would suggest that you ask a new question asking how to get the first day for the first week of the year.
Good day community.
I'm having a hard time trying to figure out a way to achieve the results I try to get. As im not very skilled with SQL queries, I start to lose my mind. What I'm trying to do is to find the highest and lowest grade on a particular test, but I also wish to get the ID or the row number (they are matching) of the rows where the MAX() and MIN() were found.
The table "Results" looks like this:
ResultID|Test_UK|Test_US|TestUK_Scr|TestUS_Scr|TestTakenOn
1 1 3 85 14 2018-11-22 00:00:00.000
2 3 1 41 94 2018-11-23 00:00:00.000
3 2 4 71 54 2018-11-24 00:00:00.000
4 4 2 51 52 2018-12-25 00:00:00.000
5 6 3 74 69 2018-12-01 00:00:00.000
6 3 6 83 57 2018-12-02 00:00:00.000
7 7 4 91 98 2018-12-03 00:00:00.000
8 4 7 88 22 2018-12-04 00:00:00.000
9 5 8 41 76 2018-12-08 00:00:00.000
10 8 5 37 64 2018-12-09 00:00:00.000
The results I get when I run my query...
TestID|TopScore|LowScore|LastDateTestTaken
1 94 85 2018-11-23 00:00:00.000
2 71 52 2018-11-25 00:00:00.000
3 83 14 2018-12-02 00:00:00.000
4 98 51 2018-12-04 00:00:00.000
5 64 41 2018-12-09 00:00:00.000
6 74 57 2018-12-02 00:00:00.000
7 91 22 2018-12-04 00:00:00.000
8 76 37 2018-12-09 00:00:00.000
This is the queries I'm working on.
This query returns the results mentioned above
WITH
-- Combine the results of UK and US tests
Combined_Results_Both_Tests AS(
select ResultID as resultID, Test_UK as TestID, Test_UK_Scr as TestScore, TestTakenOn as TestDate from Results
union all
select ResultID as resultID, Test_US as TestID, Test_US_Scr as TestScore, TestTakenOn as TestDate from Results),
--Gets TOP and WORST results of the tests, LastDateTaken (Needs to add ResultID!)
Get_Best_and_Worst_Results_And_LastTestDate AS(
SELECT TestID ,max(TestScore) AS TopScore ,min(TestScore) AS LowScore ,max(TestDate) AS LastDateTestTaken
FROM Combined_Results_Both_Tests
GROUP BY TestID)
--Final query execution
SELECT * FROM Get_Best_and_Worst_Results_And_LastTestDate
I've tried to achieve my desired results with something like this, which doesn't work and is also very inefficient. What I mean that it doesn't work, it is filled with dublicates, whenever the match is found on US and UK tests.
--Gets ReslutID of Min and Max values
Get_ResultID_Of_Results AS(
SELECT * FROM Get_Best_and_Worst_Results_And_LastTestDate A
CROSS APPLY
(SELECT ResultID FROM Results res
WHERE (A.TestID = res.Test_UK AND A.TopScore = res.Test_UK_Scr) OR
(A.TestID = res.Test_US AND A.TopScore = res.Test_UK_Scr) OR
(A.TestID = res.Test_UK AND A.LowScore = res.Test_UK_Scr) OR
(A.TestID = res.Test_US AND A.LowScore = res.Test_UK_Scr) OR
(A.TestID = res.Test_UK AND A.TopScore = res.Test_US_Scr) OR
(A.TestID = res.Test_US AND A.TopScore = res.Test_US_Scr) OR
(A.TestID = res.Test_UK AND A.LowScore = res.Test_US_Scr) OR
(A.TestID = res.Test_US AND A.LowScore = res.Test_US_Scr)) D)
SELECT * FROM Get_ResultID_Of_Results
This is the results I'm trying to achieve (extra columns that would state where Max value and Min value was found) that would state the ResultID from Results table. Also, the row numbers match the ResultIDs in the table.
TestID|TopScore|LowScore|LastDateTestTaken |MaxValueLocID|MinValueLocID|
1 94 85 2018-11-23 00:00:00.000 2 1
2 71 52 2018-11-25 00:00:00.000 3 4

Asking for any help with the solution, theoretical or even practical. Thank you!
If I follow correctly, you want to unpivot the data and aggregate:
select v.testid, max(v.score), min(v.score) max(v.TestTakenOn)
from results r cross apply
(values (Test_UK, TestUK_Scr, TestTakenOn),
(Test_US, TestUS_Scr, TestTakenOn)
) v(testid, score, TestTakenOn)
group by v.testid;
Then you can modify this using window functions:
select v.testid, max(v.score), min(v.score) max(v.TestTakenOn),
max(case when seqnum_desc = 1 then resultid end) as resultid_max,
max(case when seqnum_asc = 1 then resultid end) as resultid_min
from (select r.resultid, v.*,
row_number() over (partition by v.testid order by v.score asc) as seqnum_asc,
row_number() over (partition by v.testid order by v.score desc) as seqnum_desc
from results r cross apply
(values (Test_UK, TestUK_Scr, TestTakenOn),
(Test_US, TestUS_Scr, TestTakenOn)
) v(testid, score, TestTakenOn)
) v
group by v.testid;
with allScores (TestId, Score, TestTakenOn, valueLoc) as
(
select [Test_UK], [TestUK_Scr],[TestTakenOn], ResultId from scores
union all
select [Test_US], [TestUS_Scr],[TestTakenOn], ResultId from scores
),
maxMin (TestId, MaxScore, MinScore, LastTestDate) as (
select TestId, Max(score), Min(score), Max(TestTakenOn)
from allScores
group by TestId
)
select mm.*, a1.valueLoc as MaxValueLoc, a2.ValueLoc as MinValueLoc
from maxMin mm
inner join allScores a1
on mm.TestId = a1.TestId and mm.MaxScore = a1.score
inner join allScores a2
on mm.TestId = a2.TestId and mm.MinScore = a2.score;

"targetsales" shows how much over the target the sales is, where negative means how far below the target the sales was. How can I do the following:
1. I need to get the average for all the product for each day. Something like this:
DATE BRANCH AVERAGE_SALES_OF_ALL_PRODUCT
01/09/2014 1 33.33
02/09/2014 1 -1.67
...and so on
And then I need to have another query that shows how many days within those two weeks that there's positive average sales. Something like this:
BRANCH 2WEEKS_SINCE DAYS_WITH_POSITIVE_AVERAGE_SALES
1 53 9
Above just an example not a real result.
Sorry, hope this not too confusing. Thank you so much.
In Oracle, the date type might still have a time component. If you do not know if this is there, then use trunc() to remove it:
select trunc(date), branch, avg(targetreach)
from targetsale
group by truncdate, branch
order by 1, 2;
For the second query, you want to use case:
select branch, count(distinct case when targetreach > 0 then date end) as DaysWithPositiveSales
from targetsales
group by branch;
If you know there is one row per date per branch -- and the time component of the date is empty -- then the distinct is not necessary.
1)
SELECT TRUNC(DATE, 'DD'), BRANCH, SUM(TARGETREACH)
FROM TARGETSALE WHERE BRANCH = 1 AND WEEK BETWEEN 52 AND 53
GROUP BY TRUNC(DATE, 'DD'), BRANCH;
2)
SELECT BRANCH, SUM(DECODE(ABS(TARGETREACH), 1, 1, 0)
FROM TARGETSALE WHERE BRANCH = 1 AND WEEK BETWEEN 52 AND 53
GROUP BY BRANCH;
