SQL,SSRS, SQL SERVER, - sql-server

I have a transaction based table in SQL from which I am creating an SSRS report. I have a filter based on transaction dates, like below:
Label 7-13 value 1
Label 14-28 value 2
Label 7-28 value 3
If the user selects 1 then I need to show all the transactions which happen between 7-13 days from today. And same for others. Please advise me how I do this at the query level.

Here's an approach that includes sample data:
declare #value int
select #value = 1
;with cte as
(
select cast(getdate() as date) dt
union all
select dateadd(day, -1, dt)
from cte
where dt > getdate() - 30
)
select *
from cte
where (#value = 1 and dt between DATEADD(day, -13, cast(getdate() as date)) and DATEADD(day, -7, cast(getdate() as date)))
or (#value = 2 and dt between DATEADD(day, -28, cast(getdate() as date)) and DATEADD(day, -14, cast(getdate() as date)))
or (#value = 3 and dt between DATEADD(day, -28, cast(getdate() as date)) and DATEADD(day, -7, cast(getdate() as date)))
The key is in the where clause:
WHERE (#value = 1 AND [do this if #value = 1])
OR (#value = 2 AND [do this if #value = 2])
etc.

How I can use OPTION (MAXRECURSION 0) with cte insert into temp table

When I call this with these parameters(#MediaSellerID = 138, #StartDate = N'9/1/2020', #EndDate = N'10/7/2020') it returns data successfully.
But when I passed these parameters(#MediaSellerID = 213,#StartDate = '8/4/2020',#EndDate = N'11/25/2020')
this error occurs.
Msg 530, Level 16, State 1, Procedure GetAvailableDatesforCampaign, Line 81 [Batch Start Line 2]
The statement terminated. The maximum recursion 100 has been exhausted before statement completion.
If anyone has this solution (OPTION(MAXRECURSION 0)) then please also mention this statement place. thanks

OPTION (MAXRECURSION 0);
Here is a db<>fiddle with a much simpler example.

Working days on SQL Server using CTE in a function

I'm trying to write a function to return the number of working days between 2 dates. I have a table with all the bank holidays in which has two fields: BHID and BHDate.
I've written the following SELECT query to test out my theory and it works nicely:
DECLARE #StartDate AS Date, #EndDate AS Date
SET #StartDate = '2015-01-01'
SET #EndDate = '2015-07-01'
;WITH CTE AS (
SELECT #StartDate AS StartDate, #EndDate AS EndDate, #StartDate AS DateCalc
UNION ALL
SELECT #StartDate AS StartDate, #EndDate AS EndDate, DATEADD(dd, 1, DateCalc) AS DateCalc FROM CTE
WHERE DATEADD(dd, 1, DateCalc) <= EndDate)
SELECT COUNT(*) AS Days
FROM CTE
LEFT JOIN psd.dbo.LUBankHolidays BH
ON CTE.DateCalc = BH.BHDate
WHERE BHID IS NULL
AND LEFT(DATENAME(dw, DateCalc) ,1) <> 'S'
option (Maxrecursion 0);
But when I try and put it in a function I get some errors around the SET line, it could be me just not being quite as good on functions as the rest of my knowledge or I was wondering whether it was to do with the CTE not having been used ahead of the SET line? Here's my attempt:
CREATE FUNCTION [dbo].[WorkingDays]
(#StartDate AS Date, #EndDate AS Date
)
RETURNS INT
AS
BEGIN
DECLARE #Days AS INT
;WITH CTE AS (
SELECT #StartDate AS StartDate, #EndDate AS EndDate, #StartDate AS DateCalc
UNION ALL
SELECT #StartDate AS StartDate, #EndDate AS EndDate, DATEADD(dd, 1, DateCalc) AS DateCalc FROM CTE
WHERE DATEADD(dd, 1, DateCalc) <= EndDate)
SET #Days =
(SELECT COUNT(*) AS Days
FROM CTE
LEFT JOIN psd.dbo.LUBankHolidays BH
ON CTE.DateCalc = BH.BHDate
WHERE BHID IS NULL
AND LEFT(DATENAME(dw, DateCalc) ,1) <> 'S'
option (Maxrecursion 0);)
RETURN #Days
END
I even tried inserting the result of the INT into a temporary table and then dropping this after setting #Days before then returning #Days but this then results in an error regarding not being allowed to produce temporary tables as part of a function.
Any help would be great, I'm sure it's a small thing but just escaping me currently.
Because a CTE can only be used in a query, rather than using SET to set the variable, use SELECT instead:
SELECT #Days =
(SELECT COUNT(*) AS Days
FROM CTE …
From MSDN:
A CTE must be followed by a single SELECT, INSERT, UPDATE, or DELETE
statement that references some or all the CTE columns.
Worked it out with stuartd's help:
CREATE FUNCTION [dbo].[WorkingDays]
(#StartDate AS Date, #EndDate AS Date
)
RETURNS INT
AS
BEGIN
DECLARE #Days AS INT
;WITH CTE AS (
SELECT #StartDate AS StartDate, #EndDate AS EndDate, #StartDate AS DateCalc
UNION ALL
SELECT #StartDate AS StartDate, #EndDate AS EndDate, DATEADD(dd, 1, DateCalc) AS DateCalc FROM CTE
WHERE DATEADD(dd, 1, DateCalc) <= EndDate)
SELECT #Days =
(SELECT COUNT(*) AS Days
FROM CTE
LEFT JOIN psd.dbo.LUBankHolidays BH
ON CTE.DateCalc = BH.BHDate
WHERE BHID IS NULL
AND LEFT(DATENAME(dw, DateCalc) ,1) <> 'S')
option (Maxrecursion 0);
RETURN #Days
END
Thanks All
Use this function
CREATE FUNCTION [dbo].[WorkingDays]
(#Start_Date AS Date, #end_Date AS Date
)
RETURNS INT
AS
BEGIN
DECLARE #Days AS INT
WITH AllDays
AS ( SELECT #start_date AS [Date], 1 AS [level]
UNION ALL
SELECT DATEADD(DAY, 1, [Date]), [level] + 1
FROM AllDays
WHERE [Date] < #end_date )
SELECT #Days =COUNT(*) AS Days
FROM AllDays
LEFT JOIN psd.dbo.LUBankHolidays BH
ON AllDays.Date= BH.BHDate
WHERE BHID IS NULL
AND LEFT(DATENAME(dw, AllDays.Date) ,1) <> 'S'
RETURN #Days
END

T-SQL Date Difference for WeekDays only

I am trying to get the date difference in a given date excluding the week days.
Here is what I have:
SELECT DATEADD (w, -4, GETDATE())
This returns 2013-05-04 19:01:53.170, which means that it also counts weekends.
Same for
SELECT DATEADD (dw, -4, GETDATE())
Any help will be appreciated.
Thanks in advance.
I'm using these functions that return the non-weekend seconds between two dates:
CREATE FUNCTION [dbo].[DateDiff_NoWeekends](
#date1 DATETIME,
#date2 DATETIME
)
RETURNS INT AS BEGIN
DECLARE #retValue INT
SET #date1 = dbo.__CorrectDate(#date1, 1)
SET #date2 = dbo.__CorrectDate(#date2, 0)
IF (#date1 >= #date2)
SET #retValue = 0
ELSE BEGIN
DECLARE #days INT, #weekday INT
SET #days = DATEDIFF(d, #date1, #date2)
SET #weekday = DATEPART(dw, #date1) - 1
SET #retValue = DATEDIFF(s, #date1, #date2) - 2 * 24 * 3600 * ((#days + #weekday) / 7)
END
RETURN #retValue
END
GO
CREATE FUNCTION [dbo].[__CorrectDate](
#date DATETIME,
#forward INT
)
RETURNS DATETIME AS BEGIN
IF (DATEPART(dw, #date) > 5) BEGIN
IF (#forward = 1) BEGIN
SET #date = #date + (8 - DATEPART(dw, #date))
SET #date = DateAdd(Hour, (8 - DatePart(Hour, #date)), #date)
END ELSE BEGIN
SET #date = #date - (DATEPART(dw, #date)- 5)
SET #date = DateAdd(Hour, (18 - DatePart(Hour, #date)), #date)
END
SET #date = DateAdd(Minute, -DatePart(Minute, #date), #date)
SET #date = DateAdd(Second, -DatePart(Second, #date), #date)
END
RETURN #date
END
Here's a sql-fiddle demo for all non-weekend days in april (22).
SELECT [no weekend days in april] =
(dbo.DateDiff_NoWeekends('2013-04-01','2013-05-01')
/ 3600 / 24)
The query below gives the difference for week days alone , Ie counts the no od days between two days and subtracts the no of weekend days ,
DECLARE #StartDate DATETIME,
#EndDate DATETIME
SELECT #StartDate = '01-July-2008',
#EndDate = '30-July-2008'
;WITH DATE (Date1)
AS (
SELECT DATEADD(DAY, DATEDIFF(DAY, '19000101', #StartDate), '19000101')
UNION ALL
SELECT DATEADD(DAY, 1, Date1)
FROM DATE
WHERE Date1 < #EndDate
)
SELECT count(*) -
(
SELECT count(*)
--CONVERT(VARCHAR(15),d1.DATE1 ,110) as [Working Date],
--DATENAME(weekday, d1.Date1) [Working Day]
from DATE d1 where (DATENAME(weekday, d1.Date1)) in ('Saturday','Sunday')
)
--CONVERT(VARCHAR(15),d1.DATE1 ,110) as [Working Date],
--DATENAME(weekday, d1.Date1) [Working Day]
from DATE d1 where (DATENAME(weekday, d1.Date1)) not in ('Saturday','Sunday')
please let me know for any clarifications
Maybe I am still missing some full testing, but this works for me too: take the difference in days and then subtract 2 days for each weekend
DateDiff(d, d1, d2) - 2*DateDiff(wk, d1, d2)
Could be put in a function as well

Adding a further group into a recursive CTE

Referring back to this SO post
If there is a Grouping category "Category" which, for simplicity's sake, can be either X or Y - is it a trivial matter amending this script so that it will add in the missing dates for each of the categories ?
I assume the category will need adding into the CTE?
In other words if I have the following initial table:
...how do I get to the following:
Will upload my attempt shortly
I've called the initial table #x. I'm hoping to adapt a recursive CTE query like the following to include the field Category:
DECLARE #MinDate DATETIME;
SET #MinDate = (SELECT Min(DATE) FROM #x)
DECLARE #MaxDate DATETIME;
SET #MaxDate = (SELECT Max(DATE) FROM #x)
;WITH times AS
(
SELECT #MinDate dt , 1 depth
UNION ALL
SELECT
DATEADD(d, depth, #MinDate) dt
, 1 + depth as depth
FROM times
WHERE DATEADD(d, depth, #MinDate) <= #MaxDate
)
SELECT
*
FROM
TIMES t
LEFT OUTER JOIN #X x
ON
t.dt = x.Date
Ok - I've tied including a CROSS JOIN but it expands things incorrectly:
SELECT DISTINCT Category INTO #Cat FROM #x
DECLARE #MinDate DATETIME;
SET #MinDate = (SELECT Min(DATE) FROM #x)
DECLARE #MaxDate DATETIME;
SET #MaxDate = (SELECT Max(DATE) FROM #x)
;WITH times AS
(
SELECT
Category
, #MinDate dt
, 1 depth
FROM #Cat
UNION ALL
SELECT
c.Category
, DATEADD(d, depth, #MinDate) dt
, 1 + depth as depth
FROM
times t
CROSS JOIN #Cat c
--ON c.Category IS NOT NULL
WHERE DATEADD(d, depth, #MinDate) <= #MaxDate
)
SELECT
*
FROM
TIMES
This seems to have worked ok:
SELECT DISTINCT Category INTO #Cat FROM #x
DECLARE #MinDate DATETIME;
SET #MinDate = (SELECT Min(DATE) FROM #x)
DECLARE #MaxDate DATETIME;
SET #MaxDate = (SELECT Max(DATE) FROM #x)
;WITH times AS
(
SELECT
Category
, #MinDate dt
, 1 depth
FROM #Cat
UNION ALL
SELECT
Category
, DATEADD(d, depth, #MinDate) dt
, 1 + depth as depth
FROM
times t
WHERE DATEADD(d, depth, #MinDate) <= #MaxDate
)
SELECT
*
FROM
TIMES
Here is a solution without a calendar table (which is a must in production). You might have date range in variables, or you might go for min() and max() from the_table.
EDIT: shorter version incorporating categories into date range generation
declare #startdate datetime = '2012-1-1'
declare #enddate datetime = '2012-1-5'
; with dates([date], category) as (
select distinct #startdate, category
from the_table
union all
select dateadd (day, 1, [date]), category
from dates
where [date] < #enddate
)
select dates.date,
dates.category,
isnull(the_table.amount, 0) Amount
from dates
left join the_table
on dates.date = the_table.date
and dates.category = the_table.category
order by dates.category, dates.date
option (maxrecursion 0)
There is live test # Sql Fiddle.
New Sql Fiddle.
Something like this should do the trick:
declare #curDate datetime, #maxDate datetime
declare #count tinyint
select #curDate = convert(datetime, '20120101', 112), #maxDate = getdate()
select #count = 0
while #curDate < #maxDate
begin
select #count = count(1) from tablename where Category = 'X' and convert(varchar(8), Date, 112) = convert(varchar(8), #curDate, 112)
if #count > 0
begin
insert into tablename
select 'X', #curDate, 0
end
select #curDate = dateadd(dd, 1, #curDate)
end

Find out date difference in SQL Server

I have from date and to date in my table, I want to know total number of days between two dates without sunday, in SQL Server 2008.
give me a query..
Accept my question...
OK, so work out the total number of days, subtract the total number of weeks, and a fiddle factor for the case where the from date is a Sunday:
SELECT
DATEDIFF(dd, FromDate, ToDate)
-DATEDIFF(wk, FromDate, ToDate)
-(CASE WHEN DATEPART(dw, FromDate) = 1 THEN 1 ELSE 0 END)
try to use this as an example and work it..
DECLARE #StartDate DATETIME
DECLARE #EndDate DATETIME
SET #StartDate = '2008/10/01'
SET #EndDate = '2008/10/31'
SELECT
(DATEDIFF(dd, #StartDate, #EndDate) + 1)
-(DATEDIFF(wk, #StartDate, #EndDate) * 2)
-(CASE WHEN DATENAME(dw, #StartDate) = 'Sunday' THEN 1 ELSE 0 END)
-(CASE WHEN DATENAME(dw, #EndDate) = 'Saturday' THEN 1 ELSE 0 END)
You could do this with a CTE, and this couuld easily be turned into a scalar function:
DECLARE #startDate DATETIME = '2011-09-01'
DECLARE #endDate DATETIME = '2011-09-23'
;WITH DateRange (date) AS
(
SELECT #startDate
UNION ALL
SELECT Date+1
FROM DateRange
WHERE date<#endDate
)
SELECT COUNT(*) FROM DateRange WHERE DATENAME(dw,Date) != 'Sunday'
Returns 20 which is the number of days this month so far which are not sundays.
Here's an equivalent function which can be used:
CREATE FUNCTION dbo.NumberOfDaysExcludingSunday(
#startDate DATETIME,
#endDate DATETIME
) RETURNS INT AS
BEGIN
DECLARE #rtn INT
;WITH DateRange (date) AS
(
SELECT #startDate
UNION ALL
SELECT Date+1
FROM DateRange
WHERE date<#endDate
)
SELECT #rtn = COUNT(*) FROM DateRange WHERE DATENAME(dw,Date) != 'Sunday'
RETURN #rtn
END
Usage:
SELECT dbo.NumberOfDaysExcludingSunday(startDate,endDate)
FROM myTable
