I need some help in this my case is
1-two parameters date from , date to
2-number of team parameter that manually enter by user for later on use in some calculation
rquirement
count only working days (6days per week ) without Friday based on filtered period (date from and date to)
Code
=(COUNT(IIF(Fields!Job_Status.Value="Closed",1,Nothing))) /
((DateDiff(DateInterval.day,Parameters!DateFrom.Value,Parameters!ToDate.Value
)) * (Parameters!Number_of_teams.Value))
Note
this code is working fine but it calculate all days
thanks in advance
Try this:
=(DATEDIFF(DateInterval.Day, CDATE("2016-02-14"), CDATE("2016-02-17")) + 1)
-(DATEDIFF(DateInterval.WeekOfYear, CDATE("2016-02-14"), CDATE("2016-02-17")) * 2)
-(IIF(WeekdayName(DatePart(DateInterval.Weekday,CDATE("2016-02-14"),FirstDayOfWeek.System))="sunday",1,0)
-(IIF(WeekdayName(DatePart(DateInterval.Weekday,CDATE("2016-02-17"),FirstDayOfWeek.System))="saturday",1,0)
))
It will ruturn count of monday to friday between the given range in the above case it returns 3. For StartDate = 2016-02-14 and EndDate = 2016-02-21 it returns 5.
UPDATE: Expression to exclude friday from the count.
=(DATEDIFF(DateInterval.Day, Parameters!DateFrom.Value, Parameters!ToDate.Value) + 1)
-(DATEDIFF(DateInterval.WeekOfYear, Parameters!DateFrom.Value, Parameters!ToDate.Value) * 1)
-(IIF(WeekdayName(DatePart(DateInterval.Weekday,Parameters!ToDate.Value,FirstDayOfWeek.System))="friday",1,0))
Tested with:
DateFrom ToDate Result
2016-02-12 2016-02-19 6
2016-02-12 2016-02-18 6
2016-02-12 2016-02-15 3
It is very strange to me see a saturday and sunday as working days instead of friday.
Let me know if this helps you.
The most sustainable solution for this kind of question, in the long term, is to create a "date dimension" aka "calendar table". That way any quirks in the classification of dates that don't conform to some neat mathematical pattern can be accommodated. If your government decides to declare date X a public holiday starting from next year, just add it to your public holidays column (attribute). If you want to group by say "work days, weekends, and public holidays" no need to reinvent the wheel, just add that classification to the calendar table and everyone has the benefit of it and you don't need to worry about inconsistency in calculation/classification. You might want the first or last working day of the month. Easy, filter by that column in the calendar table.

Currently I have 2 years worth of Sales data, and my company wants a weekday to weekday comparison between the 2 years
basically the Sales Numbers for Wednesday April 1st 2020 should be compared to Wednesday April 3rd 2019 (weekday to weekday comparison, instead of calendar year)
i'm trying to come up with some sort of case statement that will allow me to add a helper column so I can then put it into an excel Pivot table, or use a join, but I'm a bit stumped on how to go about it
Basically I thought if I could come up with some way to assign a sequence to each workday, it could be done
for example Monday #1 in April could get the code MApril1 Monday #2 in April could get MApril2 Monday #1 in June could get MJune1 and so forth (I could just do that for both years and that would make it very easy)
but I just cant think of a way to write that sequence or case, any suggestions?
long story short lets say I gave you the date Wednesday April 8th 2020, how would you identify this as the second Wednesday of April 2020?
Not sure if I understood clearly but I will try to help.
Don't hesitate to tell me if I'm wrong.
I assumed you used SQL Server. Please add the SQL you use into the tags.
I would count the week number.
set datefirst 1; -- depending on the language
declare #weekNb int;
select #weekNb = datepart(week, #yourInitialDate); -- getting the number of the week
declare #dayNb = int;
select #dayNb = datepart(weekday, #yourInitialDate); -- getting the number of the day
And now, using the function from this post I would get the day from the current year :
select dbo.date_from_week_number_day(YEAR(GetDate(),weekNb,dayNb);
I'm looking to create a recurring date calculator that will correspond to EVENTS on a specific calendar date. Each event has its own rule.
For example, for EVENT A rule is "Occurs Tuesday monthly with the start date Tuesday 9-17-2019. I'm using a time dimension table with every date populated until 2025. Using these dates I was using in the WHERE clause
WHERE dayname = 'tuesday' and ( DATEDIFF(DAY, '2019-09-17', Calendar_Date) % 28 ) = 0 to get monthly tuesdays.
But I'm running into issues when there are two 5 Tuesdays in a month. 3-3-2020 and 3-31-2020. Need date populated to be 4-7-2020 instead of 3-31-2020.
Can anyone help with a solution?
With your query, you're pretty close. All you need to do is to then sub-select
SELECT MIN(CalendarDate) AS CalendarDate
FROM (your query goes here) AS d
GROUP BY YEAR(CalendarDate), MONTH(CalendarDate);
I have a course calendar events table as follows (showing only a few records for simplicity):
calendarItemID classID startDate startTime endTime
----------------------------------------------------------
1 1 2011-11-24 7pm 9pm
2 2 2011-11-02 7pm 9pm
3 1 2011-11-25 7pm 9pm
I need a query that returns courses for the UPCOMING QUARTER (not the current quarter). Is there a SQL function that can help and/or is this a case of working out the dates in the current quarter and seeing if StartDate fits within those dates. I'm looking for the most elegant way if possible.
Thanks in advance!

Straightforward, but slow approach :
WHERE DATEPART(qq,startDate) = DATEADD(qq, 1,GETDATE()) AND YEAR(startDate) =
YEAR(DATEADD(qq, 1,GETDATE()))
By slow I mean that even if you have an index on (startDate) it won't be used.
The better solution is to get start_date and end_date for the next quarter. I can see a number of ways to do so. For instance, you can create 2 scalar UDF that returns start_date and end_date respectively. You can also create 1 table-valued function that returns 1 row with 2 columns and then join it. Finally, you can just create a lookup table and manually enter start/end date for next couple of years.
Create a table called say Quarters with a useful ID say YYYYQQ, and a start and end date, then it's a simple join.
I want to perform an operation in crystal report.
I have a db table contains a date column.
I want to filter and get the rows having data created in last week(last sunday to last saturday = 7 days).For example if today is 24th August Wednesday, then I need data from 14th August(Sunday) to 20th August(Saturday).
Basically I want to find 2 dates and filter the date column.
Date1 = Date(CurrentDate)-Day(7 + WeekDayinNum(CurrentDate)) ; (Ex:for my example it will be 10)
Date2 = Date(CurrentDate)-Day(WeekDayinNum(CurrentDate))
I do not know the Date APIs properly,can anybody help me in this.
This is a common enough date range that CR provides it for you. In your record selection formula, you can just add {table.date} in LastFullWeek
From CR, "LastFullWeek specifies a range of Date values that includes all dates from Sunday to Saturday of the previous week."
Add this to the record selection formula:
{table.date_field} IN Last7Days
If today is Sunday(1) you want rows that are between 7 and 1 days old,
If today is Monday(2) you want rows that are between 8 and 2 days old,
If today is Tuesday(3) you want rows that are between 9 and 3 days old,
etc.
SELECT *
FROM `tablename`
WHERE `somedatefield` >= DATE_SUB(NOW(),INTERVAL (DAYOFWEEK(NOW()) + 6) DAY)
AND `somedatefield` <= DATE_SUB(NOW(),INTERVAL (DAYOFWEEK(NOW())) DAY)
Greetings SQL gurus,
I don't know if you can help me, but I will try. I have several large databases grouped by year (each year in a different database). I want to be able to compare values from a particular week from one year to the next. For example, "show me week 17 of 2008 vs. week 17 of 2002."
I have the following definition of weeks that ideally I would use:
Only 52 weeks each year and 7 days a week (that only takes 364 days),
The first day of the first week starts from January 2nd - which means we do not use January 1st data, and
In leap year, the first day of the first week ALSO starts from the January 2nd plus we skip Feb. 29.
Any ideas?
Thanks in advance.
Best to avoid creating a table because then you have to update and maintain it to get your queries to work.
DatePart('ww',[myDate]) will give you the week number. You may run into some issues though deciding which week belongs to which year - for example if Jan 1 2003 is on Wednesday does the week belong as week 52 in 2002 or week 1 in 2003? Your accounting department will have a day of the week that is your end of week (usually Sat). I usually just pick the year that has the most days in it. DatePart will always count the first week as 1 and in the case of the example above the last week as 53. You may not care that much either way. You can create queries for each year
SELECT DatePart('ww',[myDate]) as WeekNumber,myYearTable.* as WeekNumber
FROM myYearTable
and then join the queries to get your data. You'll loose a couple days at the end of the year if one table has 52 weeks and one has 53 (most will show as 53). Or you can do it by your weekending day - this always gives you Saturday which would push a late week into the following year.
(7-Weekday([myDate]))+[myDate]
then
DatePart('ww',(7-Weekday([myDate]))+[myDate])
Hope that helps
To get the week number
'to get the week number in the year
select datepart( week, datefield)
'to get the week number in the month
select (datepart(dd,datefield) -1 ) / 7 + 1
You don't need to complicate things thinking about leap years, etc. Just compare weeks mon to sun
SInce you havea a specifc defintion of when the week starts that is differnt that the standard used by the db, I think a weeks table is the solution to your problem. For each year create a table that defines the dates contained in each week and the week number. Then by joining to that table as well as the relevant other tables, you can ask for just the data for week 17.
Table structure
Date Week
20090102 1
20090103 1
etc.
I needed to create a query that shows BOTH year AND week numbers, like 2014-52. The year shows correct when you use the Datepart() formula to convert week 53 to week 52 in the previous year, but shows the wrong year for the week that was week 1 previously that should be week 52 now. It show that week as 2015-52 instead of 2014-52.
Furthermore, it sorts the data wrong if you only use only the week number, eg:
2014-1,2014-11,2014-2
To overcome this I created the following query to insert a 0 and also to check for days in week 1 that should still fall under week 52.
ActualWeek: IIf(DatePart("ww",[SomeDate],1,3)=52 And DatePart("ww",[SomeDate])=1, DatePart("yyyy",[SomeDate],1,3)-1,DatePart("yyyy",[SomeDate],1,3)) & "-" & IIf(DatePart("ww",[SomeDate],1,3)<10,"0" & DatePart("ww",[SomeDate],1,3),DatePart("ww",[SomeDate],1,3))
