I'm new to PostgreSQL, sorry!
I need this query to return the data ordered by month and year, but I'm not getting it and I can't adjust it.
Here we go!
select
CASE
WHEN datepart(month, created_at) = '1' THEN 'January'
WHEN datepart(month, created_at) = '2' THEN 'February'
WHEN datepart(month, created_at) = '3' THEN 'March'
WHEN datepart(month, created_at) = '4' THEN 'April'
WHEN datepart(month, created_at) = '5' THEN 'May'
WHEN datepart(month, created_at) = '6' THEN 'June'
WHEN datepart(month, created_at) = '7' THEN 'July'
WHEN datepart(month, created_at) = '8' THEN 'August'
WHEN datepart(month, created_at) = '9' THEN 'September'
WHEN datepart(month, created_at) = '10' THEN 'October'
WHEN datepart(month, created_at) = '11' THEN 'November'
WHEN datepart(month, created_at) = '12' THEN 'December'
end as Month,
datepart(year, created_at) as Year,
count (distinct id) as Countd
from table
where
created_at > CURRENT_TIMESTAMP - INTERVAL '12 months'
Group by Month, Year
Order by Month, Year desc
Thanks for all support! :D
Try this:
select
to_char(created_at, 'Month') as Month,
date_part('year', created_at) as Year,
count (distinct id) as Countd
from table
where
created_at > CURRENT_TIMESTAMP - INTERVAL '12 months'
Group by date_part('month', created_at), date_part('year', created_at)
Order by date_part('month', created_at), date_part('year', created_at) desc

I am am building a Time Dimension table in PostgreSQL with DATE_ID and DATE_DESC.
My T-SQL (works perfectly) script is:
set DATEFIRST 1
;WITH DATES AS (
SELECT CAST('2019-01-01 00:00:00.000' AS datetime) AS [DATE]
UNION ALL
SELECT DATEADD(HH,1,[DATE])
FROM DATES
WHERE DATEADD(HH,1,[DATE]) <= CAST('2019-12-31' AS datetime)
)
SELECT
DATE_ID, DATE_DESC
from
(
SELECT
CONVERT(int, CONVERT(char(8), DATE, 112)) AS DATE_ID,
DATE AS DATE_DESC
FROM
DATES)a
order by 1
OPTION (MAXRECURSION 0)
At the moment Im trying to convert this code to PostgreSQL readable one and it does not work..
Here is mine at the moment:
set EXTRACT(DOW FROM TIMESTAMP '2019-01-01 00:00:00.000')+1
;WITH DATES AS (
SELECT CAST('2019-01-01 00:00:00.000' AS timestamp) AS DATE
UNION ALL
SELECT CURRENT_DATE + INTERVAL '1 hour'
FROM DATES
WHERE CURRENT_DATE + INTERVAL '1 hour' <= CAST('2019-12-31' AS timestamp)
)
SELECT DATE_ID, DATE_DESC from
(SELECT cast(to_char((DATE)::TIMESTAMP,'yyyymmddhhmiss') as BIGInt) AS DATE_ID,
DATE AS DATE_DESC
FROM
DATES)a
order by 1
OPTION (MAXRECURSION 0)
I need all the hours (24h) between 2019-01-01 and 2019-12-31 . At the moment I think OPTION (MAXRECURSION 0) and set EXTRACT(DOW FROM TIMESTAMP '2019-01-01 00:00:00.000')+1 is not working properly.
Its a problem of Recursive CTE, In Postgresql, your desired query will be like below
WITH recursive DATES AS (
SELECT CAST('2019-01-01 00:00:00.000' AS timestamp) AS date_
UNION ALL
SELECT date_ + INTERVAL '1 hour'
FROM DATES
WHERE date_ + INTERVAL '1 hour' <= CAST('2019-12-31' AS timestamp)
)
SELECT DATE_ID, DATE_DESC from
(SELECT cast(to_char((date_)::TIMESTAMP,'yyyymmddhhmiss') as BIGInt) AS DATE_ID,
date_ AS DATE_DESC
FROM
DATES)a
order by 1

I'm trying to get a specific subset of data using "over(partition)" syntax. I've created sample data to illustrate. Running the following CTE results in the a small example result set.
I need to calculate 2 date ranges using the following definitions/pseudocode
1: Days to close = CloseDate where stat = 'Closed' minus opendate partitioned by problem
2: Days to solve = "ClosedDate where stat = 'Solved' minus opendate partitioned by problem.
I can get #1 using the over(partition) syntax, but I cannot figure out #2.

A subquery could get you the result you need.
SELECT srnumber ,
problemnumber ,
stat ,
opendate ,
closedate , --min(opendate) over(partition by problemnumber) as MinDate, max(closedate) over(partition by problemnumber) as MaxDate

DATEDIFF(mi, MIN(opendate) OVER ( ),
MAX(closedate) OVER ( ))

AND c.CloseDate <= cte.CloseDate

DATEDIFF(mi, MIN(opendate) OVER ( PARTITION BY problemnumber ),
MAX(closedate) OVER ( PARTITION BY problemnumber )) AS Days_to_Close
FROM cte
ORDER BY problemnumber ASC ,
opendate ASC
My results very closely resemble user1221684's, but I use windows functions instead of a subquery. So my answer should run a little more efficiently and it's simpler. Check it out:
SELECT *,
DATEDIFF( MI, --this is minutes. For days switch "MI" to "DAY"
MIN(CASE WHEN [Stat] = 'Open' THEN OpenDate END) OVER (PARTITION BY problemNumber),
MIN(CASE WHEN [Stat] = 'Solve' THEN CloseDate END) OVER (PARTITION BY problemNumber)
) AS Minutes_To_Solve
,
DATEDIFF( MI, --this is minutes. For days switch "MI" to "DAY"
MIN(CASE WHEN [stat] = 'Open' THEN OpenDate END) OVER (PARTITION BY problemNumber),
MIN(CASE WHEN [Stat] = 'Close' THEN CloseDate END) OVER (PARTITION BY problemNumber)
) AS Minutes_To_Close

ORDER BY OpenDate
I have to find the missing hour in my table , for frequency = 1 I have to find a record per hour, if it's not the case, I have to display the missing hour.
here's my code

I have this table called Table1 as follows:
UserID Date
1 01/01/09
1 14/01/09
1 25/01/09
1 01/02/09
1 15/02/09
2 02/02/09
2 15/02/09
I am trying to return a result that counts the number of times between the MIN(Date) and 30 days after the MIN(Date) which is DATEADD(day,30,MIN(DATE)). So it would look something like this:
UserID Count
1 3
2 2
This code below is wrong but it expresses what I am trying to achieve:
SELECT COUNT(1) AS Count
FROM Table1
GROUP BY UserID
WHERE Date BETWEEN MIN(Date) AND DATEADD(day,30,MIN(DATE))
SELECT a.UserID, COUNT(a.UserID) AS [Count]
FROM Table1 AS a
INNER JOIN
(
SELECT UserID, MIN([Date]) AS MinDate
FROM Table1
GROUP BY UserID
) AS b
ON a.UserID = b.UserID
WHERE [Date] BETWEEN MinDate AND DATEADD(day, 30, MinDate)
GROUP BY a.UserID
Try this
DECLARE #table TABLE(
UserID INT,
DDate DATETIME
)
INSERT INTO #table (UserID,DDate) SELECT 1, '01 Jan 2009'
INSERT INTO #table (UserID,DDate) SELECT 1, '14 Jan 2009'
INSERT INTO #table (UserID,DDate) SELECT 1, '25 Jan 2009'
INSERT INTO #table (UserID,DDate) SELECT 1, '01 Feb 2009'
INSERT INTO #table (UserID,DDate) SELECT 1, '15 Feb 2009'
INSERT INTO #table (UserID,DDate) SELECT 2, '02 Feb 2009'
INSERT INTO #table (UserID,DDate) SELECT 2, '15 Feb 2009'
SELECT t.UserID,
COUNT(t.UserID)
FROM #table t INNER JOIN
(
SELECT UserID,
MinDate,
DATEADD(dd, 30, MinDate) MinDataAdd30
FROM (
SELECT UserID,
MIN(DDate) MinDate
FROM #table
GROUP BY UserID
) MINDates
) DateRange ON t.UserID = DateRange.UserID
WHERE t.DDate BETWEEN DateRange.MinDate AND DateRange.MinDataAdd30
GROUP BY t.UserID
I think you'll need to use a subquery to get the minimum date. I've shown it below
as a separate query into a variable as I'd probably turn this into a table-valued function.
DECLARE #STARTDATE DATETIME
SELECT #STARTDATE = MIN(DATE) FROM Table1
SELECT COUNT(1) AS Count
FROM Table1
GROUP BY UserID
WHERE Date BETWEEN #STARTDATE AND DATEADD(day,30,#STARTDATE)
I would do it like this:
select a.UserID, count(case when DDate - MinDate <= 30 then 1 end) as Count
from (
select UserID, min(DDate) MinDate
from Table1
group by UserID
) a
inner join Table1 t on a.UserID = t.UserID
group by a.UserID
