I have a datetime field and a net field. The Sat Count field is done by =IIf(DatePart("w",Fields!DespatchDate.Value)=7,1,0)
I want to total the count of the Saturdays given a starting date and end date (typically a month).
I tried =Sum(IIf(DatePart("w",Fields!DespatchDate.Value)=7,1,0) but the total is wrong.
I also want to count Saturdays for rest of the month, e.g there's a missing 3rd Saturday in the picture.
I also want to do a total of the Net for Saturdays.
Can you point me in the direction. I can do it in SQL or in SSRS
Considering that we do not have any Input or desired output provided, I am assuming that You just want to count Saturdays in a given range:
Select COUNT(*), SUM(Net)
FROM table
WHERE Day# = 7 AND Date BETWEEN '2021-02-16' AND '2021-02-23'
Assuming you want to count saturdays even if it is not part of your dataset, what you need to do is pad out all your dates for the given range and then join it to your base data set.
This would ensure that it accounts for ALL days of the week regardless of a dispatch event occuring on that date / day.
Below is some SQL code that might help you make a start.
declare #startdate date = '2021-02-01'
declare #enddate date = '2021-02-28'
if OBJECT_ID ('tempdb..#dates') is not null
drop table #dates
;WITH mycte AS
(
SELECT CAST(#startdate AS DATETIME) DateValue
UNION ALL
SELECT DateValue + 1
FROM mycte
WHERE DateValue + 1 < #enddate
)
SELECT DateValue into #dates
FROM mycte
OPTION (MAXRECURSION 0)
select
d.DateValue
, datepart(weekday,d.DateValue) as day_no
,case when datepart(weekday,d.DateValue) = 7 then isnull(t.net,0) else 0 end as sat_net
,case when datepart(weekday,d.DateValue) = 1 then isnull(t.net,0) else 0 end as sun_net
from #dates d
left join your_table t
on d.DateValue = t.some_date
drop table #dates
Since I don't know what your required output is, I cannot summarise this any further. But you get the idea!

I have a table with PersonId's that each have a FirstSubscription date and LastSubscriptionDate.
What I need to do is between those 2 dates, generate 1 date for each month. This is for reporting purposes on the front end, as this data will end up inside PowerBI and I need these dates to join to a ReportingCalendar.
This Calendar is accessible by SQL so it can be used in this calculation. I am using it to generate the dates (using first of the month) between the First and LastSubDate but I need to find a way to join this with the rest of the ID's that way I get a list of date for each ID.
Here is my code to generate the dates.
DECLARE #MinDate DATE
DECLARE #MaxDate DATE
SET #MinDate = '2020-08-31'
SET #MaxDate = '2022-08-30'
SELECT DATEADD(month, DATEDIFF(month, 0, date), 0)
FROM dbo.ReportingCalendar
WHERE Date >= #MinDate
AND Date < #MaxDate
GROUP BY
DATEADD(month, DATEDIFF(month, 0, date), 0)
My PersonSubscription table looks like this
|PersonId|FirstSubDate|LastSubDate|
|--------|------------|-----------|
|1186 |8/31/2020 |8/30/2022 |
|2189 |7/30/2019 |7/31/2021 |
So I would want to end up with an output where each PersonId has 1 entry for each month between those 2 dates. So PersonId has 25 entries from 8/2020 until 8/2022. We don't care about the actual date of the sub since this data is looked at monthly and will primarily be looked at using a Distinct Count each month, so we only care if they were subbed at any time in that month.
I just needed to do a Cross Apply.
I took my code that got me all of the PersonId's and their FirstSubDate and LastSubDate and then did a cross apply to the code I listed above, referencing the MinDate and MaxDate with the FirstSubDate and LastSubDate.
I am trying to find the first and last business day for every month since 1986.
Using this, I can find the first day of any given month using, but just that month and it does not take into consideration whether it is a business day or not. To make it easier for now, business day is simply weekdays and does not consider public holiday.
SELECT DATEADD(s,0,DATEADD(mm, DATEDIFF(m,0,getdate()),0))
But I am not able to get the correct business day, so I created a calendar table consisting of all the weekdays and thought that I can extract the min(date) from each month, but I am currently stuck.
Date
---------------
1986-01-01
1986-01-02
1986-01-03
1986-01-06
...and so on
I have tried to get the first day of every month instead, but it does not take into account whether the day is a weekend or not. It just simply give the first day of each month
declare #DatFirst date = '20000101', #DatLast date = getdate();
declare #DatFirstOfFirstMonth date = dateadd(day,1-day(#DatFirst),#DatFirst);
select DatFirstOfMonth = dateadd(month,n,#DatFirstOfFirstMonth)
from (select top (datediff(month,#DatFirstOfFirstMonth,#DatLast)+1)
n=row_number() over (order by (select 1))-1
from (values (1),(1),(1),(1),(1),(1),(1),(1)) a (n)
cross join (values (1),(1),(1),(1),(1),(1),(1),(1)) b (n)
cross join (values (1),(1),(1),(1),(1),(1),(1),(1)) c (n)
cross join (values (1),(1),(1),(1),(1),(1),(1),(1)) d (n)
) x
I am wondering if anyone can perhaps shed some light as to how can I best approach this issue.
If you already have your calendar table with all available dates, then you just need to filter by weekday.
SET DATEFIRST 1 -- 1: Monday, 7: Sunday
SELECT
Year = YEAR(T.Date),
Month = MONTH(T.Date),
FirstBusinessDay = MIN(T.Date),
LastBusinessDay = MAX(T.Date)
FROM
Calendar AS T
WHERE
DATEPART(WEEKDAY, T.Date) BETWEEN 1 AND 5 -- 1: Monday, 5: Friday
GROUP BY
YEAR(T.Date),
MONTH(T.Date)
You should use the query to mark these days on your calendar table, so it's easy to access them afterwards.
This is how you can mix it up with the generation of the calendar table (with recursion).
SET DATEFIRST 1 -- 1: Monday, 7: Sunday
declare
#DatFirst date = '20000101',
#DatLast date = getdate();
;WITH AllDays AS
(
SELECT
Date = #DatFirst
UNION ALL
SELECT
Date = DATEADD(DAY, 1, D.Date)
FROM
AllDays AS D
WHERE
D.Date < #DatLast
),
BusinessLimitsByMonth AS
(
SELECT
Year = YEAR(T.Date),
Month = MONTH(T.Date),
FirstBusinessDay = MIN(T.Date),
LastBusinessDay = MAX(T.Date)
FROM
AllDays AS T
WHERE
DATEPART(WEEKDAY, T.Date) BETWEEN 1 AND 5 -- 1: Monday, 5: Friday
GROUP BY
YEAR(T.Date),
MONTH(T.Date)
)
SELECT
*
FROM
BusinessLimitsByMonth AS B
ORDER BY
B.Year,
B.Month
OPTION
(MAXRECURSION 0) -- 0: Unlimited
If you got already a table with all the weekdays only:
select min(datecol), max(datecol)
from BusinessOnlyCalendar
group by year(datecol), month(datecol)
But you should expand your calendar to include all those calculations you might do on date, like FirstDayOfWeek/Month/Quarter/Year, WeekNumber, etc.
When you got a column in your calendar indicating business day yes/no, it's a simple:
select min(datecol), max(datecol)
from calendar
where businessday = 'y'
group by year(datecol), month(datecol)
My table creates a new record with timestamp daily when an integration is successful. I am trying to create a query that would check (preferably automated) the number of days in a month vs number of records in the table within a time frame.
For example, January has 31 days, so i would like to know how many days in january my process was not successful. If the number of records is less than 31, than i know the job failed 31 - x times.
I tried the following but was not getting very far:
SELECT COUNT (DISTINCT CompleteDate)
FROM table
WHERE CompleteDate BETWEEN '01/01/2015' AND '01/31/2015'
Every 7 days the system executes the job twice, so i get two records on the same day, but i am trying to determine the number of days that nothing happened (failures), so i assume some truncation of the date field is needed?!
One way to do this is to use a calendar/date table as the main source of dates in the range and left join with that and count the number of null values.
In absence of a proper date table you can generate a range of dates using a number sequence like the one found in the master..spt_values table:
select count(*) failed
from (
select dateadd(day, number, '2015-01-01') date
from master..spt_values where type='P' and number < 365
) a
left join your_table b on a.date = b.CompleteDate
where b.CompleteDate is null
and a.date BETWEEN '01/01/2015' AND '01/31/2015'
Sample SQL Fiddle (with count grouped by month)
Assuming you have an Integers table*. This query will pull all dates where no record is found in the target table:
declare #StartDate datetime = '01/01/2013',
#EndDate datetime = '12/31/2013'
;with d as (
select *, date = dateadd(d, i - 1 , #StartDate)
from dbo.Integers
where i <= datediff(d, #StartDate, #EndDate) + 1
)
select d.date
from d
where not exists (
select 1 from <target> t
where DATEADD(dd, DATEDIFF(dd, 0, t.<timestamp>), 0) = DATEADD(dd, DATEDIFF(dd, 0, d.date), 0)
)
Between is not safe here
SELECT 31 - count(distinct(convert(date, CompleteDate)))
FROM table
WHERE CompleteDate >= '01/01/2015' AND CompleteDate < '02/01/2015'
You can use the following query:
SELECT DATEDIFF(day, t.d, dateadd(month, 1, t.d)) - COUNT(DISTINCT CompleteDate)
FROM mytable
CROSS APPLY (SELECT CAST(YEAR(CompleteDate) AS VARCHAR(4)) +
RIGHT('0' + CAST(MONTH(CompleteDate) AS VARCHAR(2)), 2) +
'01') t(d)
GROUP BY t.d
SQL Fiddle Demo
Explanation:
The value CROSS APPLY-ied, i.e. t.d, is the ANSI string of the first day of the month of CompleteDate, e.g. '20150101' for 12/01/2015, or 18/01/2015.
DATEDIFF uses the above mentioned value, i.e. t.d, in order to calculate the number of days of the month that CompleteDate belongs to.
GROUP BY essentially groups by (Year, Month), hence COUNT(DISTINCT CompleteDate) returns the number of distinct records per month.
The values returned by the query are the differences of [2] - 1, i.e. the number of failures per month, for each (Year, Month) of your initial data.
If you want to query a specific Year, Month then just simply add a WHERE clause to the above:
WHERE YEAR(CompleteDate) = 2015 AND MONTH(CompleteDate) = 1
I have to write a trend report for the amount of standing scaffolds in the database by week.
I can get a count of scaffolds erected by week in the example below and also dismantles using the same query but this isn't what I need.
SELECT COUNT(scaffID) Erected, WeekStart
FROM
(
SELECT ScaffID,
dateadd(week, datediff(day,0,Erected) / 7, 0) AS WeekStart
FROM Scaffolds
) o
GROUP BY WeekStart
I can get my standing scaffolds from this by putting in a date but I want the standing scaffolds on every Friday say.
Declare #staticDate As DateTime
Set #staticDate = '2/1/2015'
Select COUNT(scaffID) As StandingScaffolds
from RequestInfo
Where ( ErectDate<= #staticDate )
And ( DismantleDate>= #staticDate
or DismantleDate Is NULL
)
This is driving me crazy so any help would be extremely appreciated.
Phil
this should give you something to start with..
DECLARE
#startDate date = '2015-01-01',
#endDate date = '2015-01-28';
with myWeeks (myWeek) AS (
select DATEPART(WEEK,#startDate) myWeek
UNION ALL
select myWeek + 1 from myWeeks
where
myWeek < DATEPART(WEEK,#endDate)
)
select
w,
COUNT(s.Erected) standingScaffolds
from myWeeks w
left join Scaffolds s on
w.myWeek between DATEPART(WEEK,s.Erected) and DATEPART(WEEK,s.Dismantled)
You might want to generate a date table for this (=table with one row for each day). You can then join that with this table to get the calculations quite easily.
select d.date, count(s.scaffID)
from date d, scaffolds s
where s.erected <= d.date and
(dismantled>= d.date or dismantled is NULL) and
d.date >= #stardate and
d.date <= enddate
group by d.date
Hopefully this is ok, can't test right now.
The date table is quite useful in other cases too, for example you can have local holidays there.
I need the ability to select a start date that is 60business days prior to the current date. I have a calendar built with dates and business dates, etc. My current (and unsuccessful) method is below:
DECLARE #Mode int
SET #Mode = 0
SET #StartDate = CASE WHEN #Mode = 0
THEN (SELECT BusDate FROM Leads.dbo.Calendar
WHERE Date = DATEADD(DAY,DATEDIFF (DAY,0,GETDATE())-60,0))
WHEN #Mode = 1
THEN DATEADD(mm,DATEDIFF (mm,0,GETDATE())-2,0)
END
This method goes back 60 calendar days, not 60 business days. I'm having a challenge with getting this down to Business days. Disregard the Mode = 1 portion (this calculates by month).
Any help would be appreciated.
The Calendar table has the following fields:
SELECT [Date]
,[MMDDYYYY]
,[Year]
,[QTR]
,[Month]
,[Week]
,[YTDDay]
,[QTDDay]
,[MTDDay]
,[WeekDayNbr]
,[Quarter]
,[MonthLName]
,[MonthName]
,[DayOfWeekS]
,[DayOfWeek]
,[KindOfDay]
,[Description]
,[Period]
,[YrMo]
,[YrWk]
,[StartDate]
,[EndDate]
,[BusPeriod]
,[Holiday]
,[NonBus]
,[BusDaysInMonth]
,[BusDay]
,[BusDaysRemain]
,[BusDate]
,[YYYYMMDD]
BusDay is the business day for a month (1, 2, 3, etc). There currently is no column that says 1 for yes and 0 for No to indicate it is a business day, although I could add that. The NonBus and Holiday fields operate that way: 1 is Holiday or Non-business day (holidays and weekends) and 0 is not.
We don't know much about your calendar table but you could do something like this. Use a derived table that only consists of business days that are less than today's date and give each a row number ordered by date desc. Then select the date from 60th row.
select busdate
from
(
select *,
row_number() over (order by date desc) as dayNo
from leads.dbo.calendar
where nonBus = 0 -- Only business days
and date < cast(getdate() as date)
) busDays
where dayno = 60
