I have an order file, with order id and ship date. Orders can only be shipped monday - friday. This means there are no records selected for Saturday and Sunday.
I use the same order file to get all order dates, with date in the same format (yyyymmdd).
i want to select a count of all the records from the order file based on order date... and (i believe) full outer join (or maybe right join?) the date file... because i would like to see
20120330 293
20120331 0
20120401 0
20120402 920
20120403 430
20120404 827
etc...
however, my sql statement is still not returning a zero record for the 31st and 1st.
with DatesTable as (
select ohordt "Date" from kivalib.orhdrpf
where ohordt between 20120315 and 20120406
group by ohordt order by ohordt
)
SELECT ohscdt, count(OHTXN#) "Count"
FROM KIVALIB.ORHDRPF full outer join DatesTable dts on dts."Date" = ohordt
--/*order status = filled & order type = 1 & date between (some fill date range)*/
WHERE OHSTAT = 'F' AND OHTYP = 1 and ohscdt between 20120401 and 20120406
GROUP BY ohscdt ORDER BY ohscdt
any ideas what i'm doing wrong?
thanks!
It's because there is no data for those days, they do not show up as rows. You can use a recursive CTE to build a contiguous list of dates between two values that the query can join on:
It will look something like:
WITH dates (val) AS (
SELECT CAST('2012-04-01' AS DATE)
FROM SYSIBM.SYSDUMMY1
UNION ALL
SELECT Val + 1 DAYS
FROM dates
WHERE Val < CAST('2012-04-06' AS DATE)
)
SELECT d.val AS "Date", o.ohscdt, COALESCE(COUNT(o.ohtxn#), 0) AS "Count"
FROM dates AS d
LEFT JOIN KIVALIB.ORDHRPF AS o
ON o.ohordt = TO_CHAR(d.val, 'YYYYMMDD')
WHERE o.ohstat = 'F'
AND o.ohtyp = 1

I have a table on the database that contains statuses updated on each vehicle I have, I want to calculate how many days each vehicle spends time between two specific statuses 'Maintenance' and 'Read'.
My table looks something like this
and I want to result to be like this, only show the number of days a vehicle spends in maintenance before becoming ready on a specific day
The code I written looks like this
drop table if exists #temps1
select
VehicleId,
json_value(VehiclesHistoryStatusID.text,'$.en') as VehiclesHistoryStatus,
VehiclesHistory.CreationTime,
datediff(day, VehiclesHistory.CreationTime ,
lead(VehiclesHistory.CreationTime ) over (order by VehiclesHistory.CreationTime ) ) as days,
lag(json_value(VehiclesHistoryStatusID.text,'$.en')) over (order by VehiclesHistory.CreationTime) as PrevStatus,
case
when (lag(json_value(VehiclesHistoryStatusID.text,'$.en')) over (order by VehiclesHistory.CreationTime) <> json_value(VehiclesHistoryStatusID.text,'$.en')) THEN datediff(day, VehiclesHistory.CreationTime , (lag(VehiclesHistory.CreationTime ) over (order by VehiclesHistory.CreationTime ))) else 0 end as testing
into #temps1
from fleet.VehicleHistory VehiclesHistory
left join Fleet.Lookups as VehiclesHistoryStatusID on VehiclesHistoryStatusID.Id = VehiclesHistory.StatusId
where (year(VehiclesHistory.CreationTime) > 2021 and (VehiclesHistory.StatusId = 140 Or VehiclesHistory.StatusId = 144) )
group by VehiclesHistory.VehicleId ,VehiclesHistory.CreationTime , VehiclesHistoryStatusID.text
order by VehicleId desc
drop table if exists #temps2
select * into #temps2 from #temps1 where testing <> 0
select * from #temps2
Try this
SELECT innerQ.VehichleID,innerQ.CreationDate,innerQ.Status
,SUM(DATEDIFF(DAY,innerQ.PrevMaintenance,innerQ.CreationDate)) AS DayDuration
FROM
(
SELECT t1.VehichleID,t1.CreationDate,t1.Status,
(SELECT top(1) t2.CreationDate FROM dbo.Test t2
WHERE t1.VehichleID=t2.VehichleID
AND t2.CreationDate<t1.CreationDate
AND t2.Status='Maintenance'
ORDER BY t2.CreationDate Desc) AS PrevMaintenance
FROM
dbo.Test t1 WHERE t1.Status='Ready'
) innerQ
WHERE innerQ.PrevMaintenance IS NOT NULL
GROUP BY innerQ.VehichleID,innerQ.CreationDate,innerQ.Status
In this query first we are finding the most recent 'maintenance' date before each 'ready' date in the inner most query (if exists). Then calculate the time span with DATEDIFF and sum all this spans for each vehicle.
I'm trying to use a nested aggregate function. I know that SQL does not support it, but I really need to do something like the below query. Basically, I want to count the number of users for each day. But I want to only count the users that haven't completed an order within a 15 days window (relative to a specific day) and that have completed any order within a 30 days window (relative to a specific day). I already know that it is not possible to solve this problem using a regular subquery (it does not allow to change subquery values for each date). The "id" and the "state" attributes are related to the orders. Also, I'm using Fivetran with Snowflake.
SELECT
db.created_at::date as Date,
count(case when
(count(case when (db.state = 'finished')
and (db.created_at::date between dateadd(day,-15,Date) and dateadd(day,-1,Date)) then db.id end)
= 0) and
(count(case when (db.state = 'finished')
and (db.created_at::date between dateadd(day,-30,Date) and dateadd(day,-16,Date)) then db.id end)
> 0) then db.user end)
FROM
data_base as db
WHERE
db.created_at::date between '2020-01-01' and dateadd(day,-1,current_date)
GROUP BY Date
In other words, I want to transform the below query in a way that the "current_date" changes for each date.
WITH completed_15_days_before AS (
select
db.user as User,
count(case when db.state = 'finished' then db.id end) as Completed
from
data_base as db
where
db.created_at::date between dateadd(day,-15,current_date) and dateadd(day,-1,current_date)
group by User
),
completed_16_days_before AS (
select
db.user as User,
count(case when db.state = 'finished' then db.id end) as Completed
from
data_base as db
where
db.created_at::date between dateadd(day,-30,current_date) and dateadd(day,-16,current_date)
group by User
)
SELECT
date(db.created_at) as Date,
count(distinct case when comp_15.completadas = 0 and comp_16.completadas > 0 then comp_15.user end) as "Total Users Churn",
count(distinct case when comp_15.completadas > 0 then comp_15.user end) as "Total Users Active",
week(Date) as Week
FROM
data_base as db
left join completadas_15_days_before as comp_15 on comp_15.user = db.user
left join completadas_16_days_before as comp_16 on comp_16.user = db.user
WHERE
db.created_at::date between '2020-01-01' and dateadd(day,-1,current_date)
GROUP BY Date
Does anyone have a clue on how to solve this puzzle? Thank you very much!
The following should give you roughly what you want - difficult to test without sample data but should be a good enough starting point for you to then amend it to give you exactly what you want.
I've commented to the code to hopefully explain what each section is doing.
-- set parameter for the first date you want to generate the resultset for
set start_date = TO_DATE('2020-01-01','YYYY-MM-DD');
-- calculate the number of days between the start_date and the current date
set num_days = (Select datediff(day, $start_date , current_date()+1));
--generate a list of all the dates from the start date to the current date
-- i.e. every date that needs to appear in the resultset
WITH date_list as (
select
dateadd(
day,
'-' || row_number() over (order by null),
dateadd(day, '+1', current_date())
) as date_item
from table (generator(rowcount => ($num_days)))
)
--Create a list of all the orders that are in scope
-- i.e. 30 days before the start_date up to the current date
-- amend WHERE clause to in/exclude records as appropriate
,order_list as (
SELECT created_at, rt_id
from data_base
where created_at between dateadd(day,-30,$start_date) and current_date()
and state = 'finished'
)
SELECT dl.date_item
,COUNT (DISTINCT ol30.RT_ID) AS USER_COUNT
,COUNT (ol30.RT_ID) as ORDER_COUNT
FROM date_list dl
-- get all orders between -30 and -16 days of each date in date_list
left outer join order_list ol30 on ol30.created_at between dateadd(day,-30,dl.date_item) and dateadd(day,-16,dl.date_item)
-- exclude records that have the same RT_ID as in the ol30 dataset but have a date between 0 amd -15 of the date in date_list
WHERE NOT EXISTS (SELECT ol15.RT_ID
FROM order_list ol15
WHERE ol30.RT_ID = ol15.RT_ID
AND ol15.created_at between dateadd(day,-15,dl.date_item) and dl.date_item)
GROUP BY dl.date_item
ORDER BY dl.date_item;
I have a query which show datewise pass issued by agency. I wanted to get top 20 agency who have most pass issued here is my query
Nothing in your data id identifies "agency". If I assume you mean "agent", you can get the top 20 by aggregating and then limiting the result. In Oracle 12C+, you can use:
SELECT gp.agent_id, a.agent_name, COUNT(*)
FROM eofficeuat.gatepass gp INNER JOIN
eofficeuat.cnf_agents a
ON gp.agent_id = a.agent_id INNER JOIN
eofficeuat.cardprintlog_user u
ON gp.agent_id = u.agent_id
WHERE gp.issuedatetime BETWEN DATE '2019-09-28' AND DATE '2019-09-29'
GROUP BY gp.agent_id, a.agent_name
ORDER BY COUNT(*) DESC
FETCH FIRST 1 ROW ONLY;
In earlier versions, a subquery is needed:
SELECT *
FROM (SELECT gp.agent_id, a.agent_name, COUNT(*)
FROM eofficeuat.gatepass gp INNER JOIN
eofficeuat.cnf_agents a
ON gp.agent_id = a.agent_id INNER JOIN
eofficeuat.cardprintlog_user u
ON gp.agent_id = u.agent_id
WHERE gp.issuedatetime BETWEEN DATE '2019-09-28' AND DATE '2019-09-29'
GROUP BY gp.agent_id, a.agent_name
ORDER BY COUNT(*) DESC
) a
WHERE rownum <= 20;
Obviously, if you do mean "agency" and that is identified by different columns, you would just adjust the SELECT and GROUP BY clauses.
Also, I would advise you never to use BETWEEN on dates in Oracle. There is a time component that might cause issues.
If you intend only times on '2019-09-28', then:
gp.issuedatetime >= DATE '2019-09-28' AND
gp.issuedatetime < DATE '2019-09-29'
If you intend both the 28th and 29th:
gp.issuedatetime >= DATE '2019-09-28' AND
gp.issuedatetime < DATE '2019-09-30'
You can use LIMIT clause(12c or higher version) with TOP 20 records as following:
SELECT eofficeuat.gatepass.agent_id, eofficeuat.cnf_agents.agent_name, COUNT(1) as cnt
FROM eofficeuat.gatepass INNER JOIN
eofficeuat.cnf_agents
ON eofficeuat.gatepass.agent_id = eofficeuat.cnf_agents.agent_id INNER JOIN
eofficeuat.cardprintlog_user
ON eofficeuat.gatepass.agent_id = eofficeuat.cardprintlog_user.agent_id
WHERE eofficeuat.gatepass.issuedatetime BETWEN DATE '2019-09-28' AND DATE '2019-09-29'
GROUP BY eofficeuat.gatepass.agent_id, eofficeuat.cnf_agents.agent_name
ORDER BY cnt DESC
FETCH FIRST 20 ROWS ONLY; -- this will fetch top 20 agents
Cheers!!
I have a query that gives a sum of quantity of items on working days. on weekend and holidays that quantity value and item value is empty.
I would like that on empty days is last known quantity and item.
My query is like this:
`select a.dt,b.zaliha as quantity,b.artikal as item
from
(select to_date('01-01-2017', 'DD-MM-YYYY') + rownum -1 dt
from dual
connect by level <= to_date(sysdate) - to_date('01-01-2017', 'DD-MM-YYYY') + 1
order by 1)a
LEFT OUTER JOIN
(select kolicina,sum(kolicina)over(partition by artikal order by datum_do) as zaliha,datum_do,artikal
from
(select sum(vv.kolicinaulaz-vv.kolicinaizlaz)kolicina,vz.datum as datum_do,vv.artikal
from vlpzaglavlja vz, vlpvarijante vv
where vz.id=vv.vlpzaglavlje
and vz.orgjed='01006'
and vv.skladiste='01006'
and vv.artikal in (3069,6402)
group by vz.datum,vv.artikal
order by vv.artikal,vz.datum asc)
order by artikal,datum_do asc)b
on a.dt=b.datum_do
where a.dt between to_date('12102017','ddmmyyyy') and to_date('16102017','ddmmyyyy')
order by a.dt`
and my output is like this:
and I want this:
In short, if quantity is null use lag(... ignore nulls) and coalesce or nvl:
select dt, item,
nvl(quantity, lag(quantity ignore nulls) over (partition by item order by dt))
from t
order by dt, item
Here is the full query, I cannot test it, but it is something like:
with t as (
select a.dt, b.zaliha as quantity, b.artikal as item
from (
select date '2017-10-10' + rownum - 1 dt
from dual
connect by date '2017-10-10' + rownum - 1 <= date '2017-10-16' ) a
left join (
select kolicina, datum_do, artikal,
sum(kolicina) over(partition by artikal order by datum_do) as zaliha
from (
select sum(vv.kolicinaulaz-vv.kolicinaizlaz) kolicina,
vz.datum as datum_do, vv.artikal
from vlpzaglavlja vz
join vlpvarijante vv on vz.id = vv.vlpzaglavlje
where vz.orgjed = '01006' and vv.skladiste='01006'
and vv.artikal in (3069,6402)
group by vz.datum, vv.artikal)) b
on a.dt = b.datum_do)
select *
from (
select dt, item,
nvl(quantity, lag(quantity ignore nulls)
over (partition by item order by dt)) qty
from t)
where dt >= date '2017-10-12'
order by dt, item
There are several issues in your query, major and minor:
in date generator (subquery a) you are selecting dates from long period, january to september, then joining with main tables and summing data and then selecting only small part. Why not filter dates at first?,
to_date(sysdate). sysdate is already date,
use ansi joins,
do not use order by in subqueries, it has no impact, only last ordering is important,
use date literals when defining dates, it is more readable.
I need to select the last 12 months. As you can see on the picture, May occurs two times.
But I only want it to occur once. And it needs to be the newest one.
Plus, the table should stay in this structure, with the latest month on the bottom.
And this is the query:
SELECT Monat2,
Monat,
CASE WHEN NPLAY_IND = '4P'
THEN 'QuadruplePlay'
WHEN NPLAY_IND = '3P'
THEN 'TriplePlay'
WHEN NPLAY_IND = '2P'
THEN 'DoublePlay'
WHEN NPLAY_IND = '1P'
THEN 'SinglePlay'
END AS Series,
Anzahl as Cnt
FROM T_Play_n
where NPLAY_IND != '0P'
order by Series asc ,Monat
This is the new query
SELECT sub.Monat2,sub.Monat,
CASE WHEN NPLAY_IND = '4P'
THEN 'QuadruplePlay'
WHEN NPLAY_IND = '3P'
THEN 'TriplePlay'
WHEN NPLAY_IND = '2P'
THEN 'DoublePlay'
WHEN NPLAY_IND = '1P'
THEN 'SinglePlay'
END
AS Series, Anzahl as Cnt FROM (SELECT ROW_NUMBER () OVER (PARTITION BY Monat2 ORDER BY Monat DESC)rn,
Monat2,
Monat,
Anzahl,
NPLAY_IND
FROM T_Play_n)sub
where sub.rn = 1
It does only show the months once but it doesn't do that for every Series.
So with every Play it should have 12 months.
In Oracle and SQL-Server you can use ROW_NUMBER.
name = month name and num = month number:
SELECT sub.name, sub.num
FROM (SELECT ROW_NUMBER () OVER (PARTITION BY name ORDER BY num DESC) rn,
name,
num
FROM tab) sub
WHERE sub.rn = 1
ORDER BY num DESC;
WITH R(N) AS
(
SELECT 0
UNION ALL
SELECT N+1
FROM R
WHERE N < 12
)
SELECT LEFT(DATENAME(MONTH,DATEADD(MONTH,-N,GETDATE())),3) AS [month]
FROM R
The With R(N) is a Common Table Expression.The R is the name of the result set (or table) that you are generating. And the N is the month number.
In SQL Server you can do It in following:
SELECT DateMonth, DateWithMonth -- Specify columns to select
FROM Tbl -- Source table
WHERE CAST(CAST(DateWithMonth AS INT) * 100 + 1 AS VARCHAR(20)) >= DATEADD(MONTH, -12,GETDATE()) -- Condition to return data for last 12 months
GROUP BY DateMonth, DateWithMonth -- Uniqueness
ORDER BY DateWithMonth -- Sorting to get latest records on the bottom
So it sounds like you want to select rows that contain the last occurrence of months. Something like this should work:
select * from [table_name]
where id in (select max(id) from [table_name] group by [month_column])
The last select in the brackets will get a list of id's for the last occurrence of each month. If the year+month column you have shown is not in descending order already, you might want to max this column instead.
You can use something like this(the table dbo.Nums contains int values from 0 to 11)
SELECT DATEADD(MONTH, DATEDIFF(MONTH, '19991201', CURRENT_TIMESTAMP) + n - 12, '19991201'),
DATENAME(MONTH,DateAdd(Month, DATEDIFF(month, '19991201', CURRENT_TIMESTAMP) + n - 12, '19991201'))
FROM dbo.Nums
I suggest to use a group by for the month name, and a max function for the numeric component. If is not numeric, use to_number().
