I want to get the based on current date.
If current date is:
01st to 14th of any month, it needs to return 15th of that month
15th to 31st of any month, it needs to return last day of that month
For example:
Current_Date Exp_date
-------------------------
01-08-2019 15-08-2019
10-08-2019 15-08-2019
14-08-2019 15-08-2019
15-08-2019 31-08-2019
20-08-2019 31-08-2019
25-08-2019 31-08-2019
31-08-2019 31-08-2019
I want as much as simplified form.
We can achieve it with simple logic as below .
If You are using Sql Server version 2012 and higher versions we've EOMONTH() Function to give EndOfMonth Date .
Sample Data:
CREATE TABLE #YourTable (CurrentDate DATETIME)
INSERT INTO #YourTable (CurrentDate)SELECT '08-01-2019'
INSERT INTO #YourTable (CurrentDate) SELECT '08-10-2019'
INSERT INTO #YourTable (CurrentDate) SELECT '08-14-2019'
INSERT INTO #YourTable (CurrentDate) SELECT '08-15-2019'
INSERT INTO #YourTable (CurrentDate) SELECT '08-20-2019'
INSERT INTO #YourTable (CurrentDate) SELECT '08-25-2019'
INSERT INTO #YourTable (CurrentDate) SELECT '08-31-2019'
Query:
SELECT DATEPART(DD,CurrentDate),
case when DATEPART(DD,CurrentDate)<15 THEN DATEADD(dd,-day(CurrentDate)+15,CurrentDate)
when DATEPART(DD,CurrentDate)>14 THEN EOMONTH(CurrentDate) END AS Exp_Date
FROM #YourTable
You may try this.
select current_date,
case when datepart(day, current_date) > 14
then
DATEADD(d, -1, DATEADD(m, DATEDIFF(m, 0, current_date) + 1, 0))
else
DATEADD(D, 15, DATEADD(d, -1, DATEADD(m, DATEDIFF(m, 0, current_date) , 0)))
end as Exp_date
from yourtable
Try this:replace hardCode date With your date
SELECT CONCAT(CONCAT(CONCAT (CONCAT(CASE WHEN DAY('2017/08/25') < 14 THEN 15 else 31 end , '-'),
CASE WHEN DATEPART(month, '2017/08/25') < 10 THEN Concat('0',DATEPART(month, '2017/08/25')) else DATEPART(month, '2017/08/25') end),'-'), cast(DATEPART(year, '2017/08/25') as nvarchar(4)))
SELECT [Current_date],Exp_date,
CASE WHEN 14 BETWEEN DATEPART(DAY,[Current_date]) AND DATEPART(DAY,Exp_date)
THEN CAST(DATEADD(DAY,15-DATEPART(DAY,[Current_date]),[Current_date]) AS DATE)
ELSE CAST(DATEADD(s,-1,DATEADD(mm, DATEDIFF(m,0,[Current_date])+1,0)) AS DATE)
END
FROM MOnthData
Check this..
select case when datepart(dd, dt) between 1 and 14 then right('0'+ cast(month(dt) as varchar(2)), 2) + '-15-' + cast(year(dt) as varchar(4)) else eomonth(dt) end from test

So, I am using the following snippet on a procedure, which fills me a temporary table with the first day of each year's week, the week number and month name.
However, when I reach week 53, of 2020, it jumps to week 2 of 2021. This happens because the first of january is in the so called week 53 (which is correct), but it should also be creating another row with the first week of january 2021 (even with the sunday as being in 2020, as it should).
Snippet:
SET DATEFIRST 7
DECLARE #tblSundays TABLE (
[year] INT
,[month] INT
,[week] INT
,[date] DATETIME
)
DECLARE #DateFrom DATETIME = '2020-12-12'
,#DateTo DATETIME = '2021-06-06';
--select #DateFrom,#DateTo;
WITH CTE (dt)
AS (
SELECT #DateFrom
UNION ALL
SELECT DATEADD(d, 1, dt)
FROM CTE
WHERE dt < #DateTo
)
INSERT INTO #tblSundays
SELECT datepart(year, dt)
,datepart(month, dt)
,datepart(week, dt)
,dt
FROM CTE
WHERE datepart("dw", dt) = 1
OPTION (MAXRECURSION 1000)
;
select * from #tblSundays
Is there any way that I can do this within this snippet, or should I create a manual verification?
Thanks!
You should do a couple of little tricks to set week 1 to the first Sunday of the year (tested for the next 30 years):
set datefirst 7
declare #tblSundays table ([year] int, [month] int, [week] int, [date] date)
declare #DateFrom datetime = '20201212', #DateTo datetime = '20510112';
-- Get the next closest Sunday
select #DateFrom = dateAdd(wk, dateDiff(wk, 0, #datefrom - 1 ), 0) + 6
with CTE (dt) as (
select #DateFrom
union all
select dateAdd(dd, 7, dt) from CTE where dt < #DateTo
)
insert into #tblSundays
select datePart(yy, dt),
datePart(mm, dt),
datePart(wk, dt - (1 + (datePart(dy, dt) + 5) % 7) % 7),
dt
from CTE
-- where datepart(dw, dt) = 1
option (maxrecursion 1600);
select *, datePart(wk, [date]) as [standard_wk]
from #tblSundays
I don't see how you could have those two condition on that same snippet, but you could add a second query there to complete what you are trying to do.
Something like this, maybe:
SET datefirst 7
DECLARE #tblSundays TABLE
(
[year] INT,
[month] INT,
[week] INT,
[date] DATETIME
)
DECLARE #DateFrom DATETIME = '2020-12-12',
#DateTo DATETIME = '2021-06-06';
--select #DateFrom,#DateTo;
WITH cte (dt)
AS (SELECT #DateFrom
UNION ALL
SELECT Dateadd(d, 1, dt)
FROM cte
WHERE dt < #DateTo)
INSERT INTO #tblSundays
SELECT Datepart(year, dt),
Datepart(month, dt),
Datepart(week, dt),
dt
FROM cte
WHERE Datepart("dw", dt) = 1
OPTION (maxrecursion 1000);
--second new query
WITH cte (dt)
AS (SELECT #DateFrom
UNION ALL
SELECT Dateadd(d, 1, dt)
FROM cte
WHERE dt < #DateTo)
INSERT INTO #tblSundays
SELECT Datepart(year, dt),
Datepart(month, dt),
Datepart(week, dt),
dt
FROM cte
WHERE Datepart("dw", dt) <> 1
AND Datepart(day, dt) = 1
AND Datepart(week, dt) NOT IN (SELECT week
FROM #tblSundays)
OPTION (maxrecursion 1000);
SELECT *
FROM #tblSundays
ORDER BY year,
month,
week
Would that be OK?
Starting data:
Desired results something like this:
So it calculated the number of hours until the end of StartDateTime, if the EndDateTime is greater than end of day for StartDateTime. Then for every full day in between, it calculates 24 hours (this could stretch numerous days). And then when it gets to the EndDateTime - it calculates time from midnight (morning) to EndDateTime
I'm reading that I will probably need to use a recursive CTE, but I don't have any experience with recursions and am struggling.
this might get tricky, but I guess it can be solved using so called number table - i.e. table which has only one column populated with number sequence. In our case 0 based sequence.
The trick here is to get the number of days between start and end datetime. This value used in join between the data table and the numbers table will create the needed extra rows for each per day interval.
Of course we also have to setup properly start and end datetime of each day interval (CASE terms in the CTE)
Then we get for each per day interval number of minutes and divide by 60 to get proper decimal value.
Hope this helps.
Lets see the code:
-- input data
DECLARE #v_Dates TABLE
(
id varchar(20),
StartDateTime SMALLDATETIME,
EndDateTime SMALLDATETIME
)
INSERT INTO #v_Dates (id, StartDateTime, EndDateTime)
VALUES ('example 1', '02-17-2019 0:45', '02-19-19 12:30'),
('example 2', '02-21-2019 18:00', '02-22-19 12:15'),
('example 3', '02-22-2019 20:15', '02-22-19 20:30');
-- so called Number table which holds numbers 0 - 9999 in this case
DECLARE #v_Numbers TABLE
(
Number INT
);
-- populating the number table
INSERT INTO #v_Numbers
SELECT TOP 10000 ROW_NUMBER() OVER(ORDER by t1.number) - 1 as Number
FROM master..spt_values t1
CROSS JOIN master..spt_values t2
-- we parse the dates into the per day intervals
;WITH IntervalsParsed(id, StartDateTime, EndDateTime, Number, IntervalStartDateTime, IntervalEndDateTime) AS
(
SELECT id
,StartDateTime
,EndDateTime
,Number
, InervalStartDateTime = CASE
WHEN D.StartDateTime > DATEADD(day, DATEDIFF(day, 0, D.StartDateTime), N.Number) THEN D.StartDateTime
ELSE DATEADD(day, DATEDIFF(day, 0, D.StartDateTime), N.Number)
END
, IntervalEndDateTime = CASE
WHEN D.EndDateTime < DATEADD(day, DATEDIFF(day, 0, D.StartDateTime), N.Number + 1) THEN D.EndDateTime
ELSE DATEADD(day, DATEDIFF(day, 0, D.StartDateTime), N.Number + 1)
END
FROM #v_Dates D
--this join basically creates the needed number of rows
INNER JOIN #v_Numbers N ON DATEDIFF(day, D.StartDateTime, D.EndDateTime) + 1 > N.Number
)
-- final select
SELECT id
, StartDateTime
, EndDateTime
, IntervalStartDateTime
, IntervalEndDateTime
, Number
, DecimalValue = CAST( DATEDIFF(minute, IntervalStartDateTime, IntervalEndDateTime) AS DECIMAL)/60
FROM IntervalsParsed
ORDER BY id, Number
Just another option is an ad-hoc tally table in concert with a CROSS APPLY
Example
Select A.[column1]
,A.[StartDateTime]
,A.[EndDateTime]
,Hours = sum(1) / 60.0
From #YourTable A
Cross Apply (
Select Top (DateDiff(MINUTE,[StartDateTime],[EndDateTime])+1)
D=DateAdd(MINUTE,-1+Row_Number() Over (Order By (Select Null)),[StartDateTime])
From master..spt_values n1,master..spt_values n2
) B
Group By [column1],[StartDateTime],[EndDateTime],cast(D as Date)
Returns
This may be little complicated, but here is one way to use recursive cte to get the output. You can add the start date with one day as long as it is less than end date of your column. Also declared a Static value to make sure we can get difference of 24 hours.

How can I get the date of specific day ? Like if I have Thursday or month number ?
If I give 12 for instance I want to get the date of 12th day of this month. Or if I give 'Sun' or 'Sat' is it possible to get the dates of these days ?
DATEFROMPARTS function can construct a date from day, month and year.
DATEPARTS does the opposite - gives you the day, month, year, hour, etc. of a date. Or you can use functions like YEAR, MONTH and DAY.
You can deconstruct the value returned by GETDATE function and construct whatever date you want. Here is for example how to get the date for 12th day of the current month:
select DATEFROMPARTS(YEAR(GETDATE()), MONTH(GETDATE()), 12)
Converting 'Sun' or 'Sat' to date is a bit more difficult. First, they aren't quite deterministic. If today is Friday, "Sunday this week" means "next Sunday" in some parts of the world and "last Sunday" in others. You should implement your own logic based on the value returned by DATEPART(dw, GETDATE()) (which will give you the day of the week).

Use a recursive CTE with the EOMONTH function.
DECLARE #startdate DATE = '2016-01-01'
;WITH CTE
AS
(
SELECT EOMONTH(GETDATE()) as 'Dates'
UNION ALL
SELECT EOMONTH(DATEADD(MONTH, -1, [Dates]))
FROM CTE WHERE Dates > DATEADD(MONTH, 1, #startdate)
)
SELECT * FROM CTE
with temp as (select -1 i union all
select i+1 i from temp where i < 8)
select DATEADD(s,-1,DATEADD(mm, DATEDIFF(m,0,GETDATE())+i*-1,0)) from temp
declare #LASTMONTH date = '2018-10-01';
WITH MTHS AS (
SELECT dateadd(month,month(getdate()),dateadd(year,year(getdate()) - 1900, 0)) aday
UNION ALL
SELECT DATEADD(month,1,aday) from MTHS WHERE aday <= #LASTMONTH
),
LASTDAYS AS (SELECT DATEADD(day,-1,aday) finaldayofmonth from MTHS)
select * from LASTDAYS
Here is a version that goes forward or backwards as appropriate
declare #LASTMONTH date = '2013-10-01';
WITH DIF AS (SELECT CASE WHEN
YEAR(#LASTMONTH) * 12 + MONTH(#LASTMONTH)
>= YEAR(GETDATE()) * 12 + MONTH(getdate()) THEN 1 ELSE -1 END x),
MTHS AS (
SELECT dateadd(month,month(getdate()),dateadd(year,year(getdate()) - 1900, 0)) aday
UNION ALL
SELECT DATEADD(month,(SELECT X from dif),aday) from MTHS
WHERE month(aday) != month(dateadd(month,1,#LASTMONTH)) or YEAR(aday) != YEAR(dateadd(month,1,#LASTMONTH))
),
LASTDAYS AS (SELECT DATEADD(day,-1,aday) finaldayofmonth from MTHS)
select * from LASTDAYS order by finaldayofmonth
Here's one approach, using a CTE to generate a list of incrementing numbers to allow us to then have something to select from and use in a DATEADD to go back for the appropriate number of months.
Typically, if you're doing this quite frequently, instead of generating numbers on the fly like this with the CROSS JOIN, I'd recommend just creating a "Numbers" table that just holds numbers from 1 to "some number high enough to meet your needs"
DECLARE #Date DATE = '20151201'
DECLARE #MonthsBackToGo INTEGER
SELECT #MonthsBackToGo = DATEDIFF(mm, #Date, GETDATE()) + 1;
WITH _Numbers AS
(
SELECT TOP (#MonthsBackToGo) ROW_NUMBER() OVER (ORDER BY o.object_id) AS Number
FROM sys.objects o
CROSS JOIN sys.objects o2
)
SELECT EOMONTH(DATEADD(mm, -(Number- 1), GETDATE())) AS last_day_of_month
FROM _Numbers
This should scale out no matter how far you go back or forward for your originating table or object.
SET NOCOUNT ON;
DECLARE #Dates TABLE ( dt DATE)
DECLARE #Start DATE = DATEADD(YEAR, DATEDIFF(YEAR, 0, GETDATE()), 0)
DECLARE #End DATE = DATEADD(YEAR, 1, #Start)
WHILE #Start <= #End
BEGIN
INSERT INTO #Dates (dt) VALUES (#Start)
SELECT #Start = DATEADD(DAY, 1, #Start)
END
; With x as
(
Select
dt
, ROW_NUMBER() OVER(PARTITION BY DATEPART(YEAR, Dt), DATEPART(MONTH, Dt) ORDER BY Dt Desc) AS rwn
From #Dates
)
Select *
From x
WHERE rwn = 1
ORDER BY Dt
This was cribbed together quick based on a couple different SO answers for the parts:
DECLARE #startdate datetime, #enddate datetime
set #startdate = '2015-12-01'
set #enddate = getdate()
;WITH T(date)
AS
(

I want records from table which stores the current date when a record is inserted with in current week only.
I have tried:
SELECT PId
,WorkDate
,Hours
,EmpId
FROM Acb
WHERE EmpId=#EmpId AND WorkDate BETWEEN DATEADD(DAY, -7, GETDATE()) AND GETDATE()
Do it like this:
SET DATEFIRST 1 -- Define beginning of week as Monday
SELECT [...]
AND WorkDate >= dateadd(day, 1-datepart(dw, getdate()), CONVERT(date,getdate()))
AND WorkDate < dateadd(day, 8-datepart(dw, getdate()), CONVERT(date,getdate()))
Explanation:
datepart(dw, getdate()) will return the number of the day in the current week, from 1 to 7, starting with whatever you specified using SET DATEFIRST.
dateadd(day, 1-datepart(dw, getdate()), getdate()) subtracts the necessary number of days to reach the beginning of the current week
CONVERT(date,getdate()) is used to remove the time portion of GETDATE(), because you want data beginning at midnight.
A better way would be
select datepart(ww, getdate()) as CurrentWeek
You can also use wk instead of ww.
Datepart Documentation
Its Working For Me.
Select * From Acb Where WorkDate BETWEEN DATEADD(DAY, -7, GETDATE()) AND DATEADD(DAY, 1, GETDATE())
You have to put this line After the AND Clause AND DATEADD(DAY, 1, GETDATE())
datepart(dw, getdate()) is the current day of the week, dateadd(day, 1-datepart(dw, getdate()), getdate()) should be the first day of the week, add 7 to it to get the last day of the week
You can use following query to extract current week:
select datepart(dw, getdate()) as CurrentWeek
SET DATEFIRST 1;
;With CTE
AS
(
SELECT
FORMAT(CreatedDate, 'MMMM-yyyy') as Months,
CASE
WHEN YEAR(DATEADD(DAY, 1-DATEPART(WEEKDAY, Min(CreatedDate)), Min(CreatedDate))) < YEAR(Min(CreatedDate))
THEN FORMAT(DATEADD(YEAR, DATEDIFF(YEAR, 0,DATEADD(YEAR, 0 ,GETDATE())), 0) ,'MMM dd') + ' - ' + FORMAT(DATEADD(dd, 7-(DATEPART(dw, Min(CreatedDate))), Min(CreatedDate)) ,'MMM dd')
ELSE
FORMAT(DATEADD(DAY, 1-DATEPART(WEEKDAY, Min(CreatedDate)), Min(CreatedDate)) ,'MMM dd') + ' - ' + FORMAT(DATEADD(dd, 7-(DATEPART(dw, Min(CreatedDate))), Min(CreatedDate)) ,'MMM dd')
END DateRange,
Sum(ISNULL(Total,0)) AS Total,
sum(cast(Duration as int)) as Duration
FROM TL_VriandOPI_Vendorbilling where VendorId=#userID and CompanyId=#CompanyID
Group By DATEPART(wk, CreatedDate) ,FORMAT(CreatedDate, 'MMMM-yyyy')
)
SELECT Months,DateRange,Total,Duration,
case when DateRange=(select FORMAT(DATEADD(DAY, 1-DATEPART(WEEKDAY, Min(getdate())), Min(getdate())) ,'MMM dd') + ' - ' +
FORMAT(DATEADD(dd, 7-(DATEPART(dw, Min(getdate()))), Min(getdate())) ,'MMM dd'))
then 1 else 0 end as Thisweek
FROM CTE order by Months desc
Using DATEDIFF works as well, however a bit hacky since it doesn't care about datefirst:
set datefirst 1; -- set monday as first day of week
declare #Now datetime = '2020-09-28 11:00';
select *
into #Temp
from
(select 1 as Nbr, '2020-09-22 10:00' as Created
union
select 2 as Nbr, '2020-09-25 10:00' as Created
union
select 2 as Nbr, '2020-09-28 10:00' as Created) t
select * from #Temp where DATEDIFF(ww, dateadd(dd, -##datefirst, Created), dateadd(dd, -##datefirst, #Now)) = 0 -- returns 1 result
select * from #Temp where DATEDIFF(ww, dateadd(dd, -##datefirst, Created), dateadd(dd, -##datefirst, #Now)) = 1 -- returns 2 results
drop table #Temp
