The below code gives a count of 1 for each day, and accumulates from today (13/04/2021) til the end of the month and sums them for Saturdays, Sundays and Week days.
;WITH mycte AS (
SELECT GETDATE() DateValue
UNION ALL
SELECT DateValue + 1
FROM mycte
WHERE DateValue < EOMONTH(dateadd(day,-1, getdate()))
)
select
count(case when datepart(dw, DateValue) = 1 then 1 end) SunCount
, count(case when datepart(dw, DateValue) = 7 then 1 end) SatCount
, count(case when datepart(dw, DateValue) between 1 and 7 then 1 end) WeekCount
from mycte
For today (13/04/2021) I would expect the count to be Saturday = 2, Sunday = 2, and Weekdays to be 14 but instead I get 18 til the end of April - why is that?
I think it is because 'between' includes 1 and 7 again, below query should give you remaining 14 week days
;WITH mycte AS (
SELECT GETDATE() DateValue
UNION ALL
SELECT DateValue + 1
FROM mycte
WHERE DateValue < EOMONTH(dateadd(day,-1, getdate()))
)
select
count(case when datepart(dw, DateValue) = 1 then 1 end) SunCount
, count(case when datepart(dw, DateValue) = 7 then 1 end) SatCount
, count(case when datepart(dw, DateValue) between 2 and 6 then 1 end) WeekCount

The below code when run for the last day of the month it is giving me a week day count of 1 when it should be 0 - how can I fix it?
Declare #EndDate DateTime = '03-31-2021'
;WITH mycte AS (
SELECT #EndDate + 1 DateValue
UNION ALL
SELECT DateValue + 1
FROM mycte
WHERE DateValue < EOMONTH(#EndDate)
)
select
count(case when datepart(dw, DateValue) = 1 then 1 end) SunCount
, count(case when datepart(dw, DateValue) = 7 then 1 end) SatCount
, count(case when datepart(dw, DateValue) between 2 and 6 then 1 end) WeekCount
from mycte
Your initial CTE is actually creating a date of 2021-04-01 which is a week day, so that's where your count of 1 is coming from. If you want to restrict the counts to just the month in question, you could add a WHERE clause to your end query like this. This way, you get zeros for all counts.
Declare #EndDate DateTime = '03-31-2021'
;WITH mycte AS (
SELECT #EndDate + 1 DateValue
UNION ALL
SELECT DateValue +1
FROM mycte
WHERE DateValue < EOMONTH(#EndDate)
)
select
count(case when datepart(dw, DateValue) = 1 then 1 end) SunCount
, count(case when datepart(dw, DateValue) = 7 then 1 end) SatCount
, count(case when datepart(dw, DateValue) between 2 and 6 then 1 end) WeekDayCount
from mycte
where DATEPART(MM,DateValue)=DATEPART(MM,#EndDate)
CTE created to count the number of days left from today's date to end of current month. So my report for today (30 March 2021) did not count tomorrow's date 31 March 2021.
declare #DespatchTo Date = '03-30-2021'
WITH mycte AS
(
SELECT CAST(Convert(date,getdate()) AS DATETIME) DateValue
UNION ALL
SELECT DateValue + 1
FROM mycte
WHERE DateValue < DATEADD(d, -1, DATEADD(m, DATEDIFF(m, 0, #DespatchTo) + 1, 0)) --03-31-2021
)
SELECT SUN.Count as SunCount, SAT.Count as SatCount, WK.Count as WeekCount
FROM
(SELECT count(*) as Count
FROM mycte
WHERE DatePart("w",DateValue) = 1
group by DatePart("w",DateValue))
As SUN,
(SELECT count(*) as Count
FROM mycte
WHERE DatePart("w",DateValue) = 7
group by DatePart("w",DateValue))
As SAT,
(SELECT distinct SUM(COUNT(*)) OVER() AS Count
FROM mycte
WHERE DatePart("w",DateValue) > 1 AND DatePart("w",DateValue) < 7
group by DatePart("w",DateValue))
As WK
Which returns blank/null results. How can I return as 0?
here is what you need to do:
;WITH mycte AS (
SELECT GETDATE() DateValue
UNION ALL
SELECT DateValue + 1
FROM mycte
WHERE DateValue < EOMONTH(GETDATE())
)
select
count(case when datepart(dw, DateValue) = 1 then 1 end) SUN
, count(case when datepart(dw, DateValue) = 7 then 1 end) SAT
, count(case when datepart(dw, DateValue) between 2 and 6 then 1 end) WK
from mycte
if you want to exclude today, you can adjust cte :
;WITH mycte AS (
SELECT GETDATE() + 1 DateValue
WHERE GETDATE() <> EOMONTH(GETDATE())
UNION ALL
SELECT DateValue + 1
FROM mycte
WHERE DateValue < EOMONTH(GETDATE())
)
select
count(case when datepart(dw, DateValue) = 1 then 1 end) SUN
, count(case when datepart(dw, DateValue) = 7 then 1 end) SAT
, count(case when datepart(dw, DateValue) between 2 and 6 then 1 end) WK

How the current code works: Given a date range, the number of months in each year between two dates. IE 1/1/2014 - 1/18/2015 would give two columns "2014" and 2015" the value of 2014 is 12 and the value of 2015 is 1 signifying that there are 13 months between the specified dates.
What I am hoping to achieve is something similar to
Start Date End Date Month 1 Month 2 Month 3
-----------------------------------------------------
1/1/2014 3/8/2014 4 4 1
Dynamic SQL solutions aside (search for dynamic pivot in TSQL), I whipped up a couple of answers. Since your question is unclear whether you want weeks or months, I put together a quick one for each.
Months Example Here:
declare #startdate date = '1/1/2014', #enddate date = '3/1/2015'
select p.*
from (
select #startdate as StartDate, #enddate as EndDate, right(convert(varchar,(dateadd(mm,RowID-1,#startdate)),105),4) [Group]
from (
select *, row_number()over(order by name) as RowID
from master..spt_values
) d
where d.RowID <= datediff(mm, #startdate, #enddate)
) t
pivot (
count([Group]) for [Group] in (
[2014],[2015]
)
) p
Weeks Example Here:
declare #startdate date = '1/1/2014', #enddate date = '3/1/2015'
select p.*
from (
select #startdate as StartDate, #enddate as EndDate, right(convert(varchar,(dateadd(ww,RowID-1,#startdate)),105),7) [Group]
from (
select *, row_number()over(order by name) as RowID
from master..spt_values
) d
where d.RowID <= datediff(ww, #startdate, #enddate)
) t
pivot (
count([Group]) for [Group] in (
[01-2014]
, [02-2014]
, [03-2014]
, [04-2014]
, [05-2014]

This is more verbose but my focus was (a) to avoid repeating expressions and (b) to simulate all of the input parameters intended to be fed to the stored procedure so that the results are filtered on the desired user / date. Note that the #whichdate parameter is reeled back to the preceding Saturday at midnight, regardless of which day of the week it is or what time is associated with it.
Input parameters:
DECLARE #whichdate DATETIME;
SET #whichdate = '2011-08-08T12:34:00';
DECLARE #whichforUID VARCHAR(32);
SET #whichforUID = 'user193';
Body (just comment out the DECLARE #t / INSERT #t lines, and change #t in the first CTE to the real table name:
SET #whichdate = DATEADD(DAY, -DATEPART(WEEKDAY, #whichdate), #whichdate);
SET #whichdate = DATEADD(DAY, 0, DATEDIFF(DAY, 0, #whichdate));
DECLARE #t TABLE(clocktime DATETIME, for_UID VARCHAR(32), in1_out0 BIT);

I would like to create a query that would count how many records were created in the last 7, 14 and 28 days. My result would return something like:
7Days 14Days 28Days
21 35 56
I know how to for each timepsan e.g. 7 days, but I do I capture all three in one query?
select count(*) from Mytable
where Created > DATEADD(day,-8, getdate())
Also not pretty, but doesn't rely on subqueries (table/column names are from AdventureWorks). The case statement returns 1 if it falls within your criteria, 0 otherwise - then you just sum the results :
select sum(case when datediff(day, modifieddate, getdate()) <= 7
then 1 else 0 end) as '7days',
sum(case when datediff(day, modifieddate, getdate()) > 7
and datediff(day, modifieddate, getdate()) <= 14
then 1 else 0 end) as '14days',
sum(case when datediff(day, modifieddate, getdate()) > 14
and datediff(day, modifieddate, getdate()) <= 28
then 1 else 0 end) as '28days'
from sales.salesorderdetail
Edit: Updated the datediff function - the way it was written, it would return a negative number (assuming modifieddate was in the past) causing all items to fall under the first case. Thanks to Andriy M for pointing that out
It isn't the prettiest code in the world, but it does the trick. Try selecting from three subqueries, one for each range.
select * from
(select COUNT(*) as Cnt from Log_UrlRewrites where CreateDate >= DATEADD(day, -7, getdate())) as Seven
