I want to schedule the mailing of a Cognos report, always using the current date. So, for example: today, I want to e-mail the report with data up until the 28th, but tomorrow it should contain data up until the 29th.
How can I achieve this?
Thanks in advance!
If you're expecting code, you didn't provide enough information, but let me try...
Assuming the "date" data against which you want to filter is in a query item named [Date] which is in a query subject named [Time] which is in a namespace named [namespace], create a filter like this:
[namespace].[Time].[Date] = current_date
If you want up to the current date which includes the days leading up to it you can use what dougp posted slightly modified.
[namespace].[Time].[Date] <= current_date
to ensure the where clause is pushed down to the database, I personally like to use a macro for current_date. So the expression becomes
[namespace].[Time].[Date] <= # timestampMask ( $current_timestamp , 'yyyy-mm-dd' ) #

I am using relation SQL as a source for my query as below
select * from table where date = ?
what I need is when the user runs the report, it should prompt to date parameter. the default date should be the current date and there should be a calendar to select the date.
i am not using any universal here, so don't know what to do?
I think this is going to be as close as you can get.
select *
from table
where date = #Prompt('Enter Date:','D',,Mono,Free,Not_Persistent,,User:0)
Today's date is defaulted, but not selected. Be cautious with clicking on "Now". That will give you today's date with the current system time which is likely not what you want. You could convert your #Prompt function result to a datatype that does not include the time if you want users to be able to click "Now". In my opinion it is simple enough to instruct users to click the highlighted date for today's date.
I have a list of Rest objects. It's django model
class Rest(models.Model):
product = models.ForeignKey('Product', models.DO_NOTHING)
date = models.DateTimeField()
rest = models.FloatField()
I want to select objects from it for today's date. I do it like this. Maybe there is some more convenient and compact way?
for rest in rests_list:
if rest.date.day == datetime.now().day:
result.append(rest)
First - datetime.now().day will get you the day of the month (e.g. 18 if today is 18th March 2020), but you've said you want today's date. The below is on the assumption you want today's date, not the day of the month.
(NOTE: weAreStarDust pointed out that the field is a DateTimeField, not a DateField, which I missed and have updated the answer for)
The way you are doing it right now seems like it might be fetching all of the Rests from the database and then filter them in your application code (assuming rests_listcomes from something likeRest.objects.all()`. Generally, you want to do as much filtering as possible on the database query itself, and as little filtering as possible in the client code.
In this case, what you probably want to do is:
from datetime import date
Rest.objects.filter(date__date=date.today())
That will bring back only the records that have a date of today, which are the ones you want.
If you already have all the rests somehow, and you just want to filter to the ones from today then you can use:
filter(lambda x: x.date.date() == date.today(), rests_list)
That will return a filter object containing only the items in rests_list that have date == date.today(). If you want it as a list, rather than an iterable, you can do:
list(filter(lambda x: x.date.date() == date.today(), rests_list))
or for a tuple:
tuple(filter(lambda x: x.date.date() == date.today(), rests_list))
NOTE:
If you actually want to be storing only a date, I would suggest considering use of a DateField (although not if you want to store any timezone information).
If you want to store a DateTime, I would consider renaming the field from date to datetime, or started_at - calling the field date but having a datetime can be a bit confusing and lead to errors.
As docs says
For datetime fields, casts the value as date. Allows chaining additional field lookups. Takes a date value.
from datetime import datetime
Rest.objects.filter(date__date = datetime.now().day)
You can use the django filter for filtering and get only today's date data from your model. No need to fetch all data first and then apply loop for get today's date data. You have to write your query like ...
import datetime
Rest.objects.filter(date__date = datetime.date.today())
But be sure that timezone should be same for database server and web server
I have a column of data [Sales ID] that bringing in duplicate data for an analysis. My goal is to try and limit the data to pull unique sales ID's for the max day of every month in the analysis only (instead of daily). Im basically trying to get it to only pull in unique sales ID values for the last the day of every month in the analysis ,and if the current day is the last day so far then it should pull that in. So it should pull in the MAX date in any given month. Please how do i write an expresion with the [Sales ID] column and [Date ] column to acieve this?
Probably the two easiest options are to
1) Adjust the SQL as niko mentioned
2) Limit the visualization with the "Limit Data Using Expression" option, using the following:
Rank(Day([DATE]), "desc", Month([DATE]), Year([DATE])) = 1
If you had to do it in the Data on Demand section (maybe the IL itself is a usp or you don't have permission to edit it), my preference would be to create another data table that only has the max dates for each month, and then filter your first data table by that.
However, if you really need to do it in the Data on Demand section, then I'm guessing you don't have the ability to create your own information links. This would mean you can't key off additional data tables, and you're probably going to have to get creative.
Constraints of creativity include needing to know the "rules" of your data -- are you pulling the data in daily? Once a week? Do you have today's data, or today - 2? You could probably write a python script to grab the last day of every month for the last 10 years, and then whatever yesterday's date was, and throw all those values into a document property. This would allow you to do a "Values from Property".
(Side Note: I want to say you could also do it directly in the expression portion with something like an extremely long
Date(DateTimeNow()),DateAdd("dd",-1,Date(Year(DateTimeNow()), Month(DateTimeNow()), 1))
But Spotfire is refusing to accept that as multiple values. Interestingly, when I pull the logic for a StringList property, it gives this: $map("${udDates}", ","), which suggests commas are an accurate methodology, but I get an error reading "Expected 'End of expression' but found ','" . Uncertain if this is a Spotfire issue, or related to my database connection)
tl;dr -- Doing it in the Data on Demand section is probably convoluted. Recommend adjusting in SQL if possible, and otherwise limiting in the visualization
I have data that is provided to me that includes the routed date and the service restoration date. From that it's pretty easy to generate a pivot table that generates a table with the date of the month, then a count of received tickets (routed), and the count of closed tickets. I'm trying to generate a calculated field (Pivot -> Options -> Fields, Items & Sets -> Calculated Field) to derive the delta.
When I use =Received - Closed, I get the difference in date rather than the delta in the counts. Can anyone point me in a direction on how I may calculate it? If it was static content it would be easy peasy, but I'm not getting the knack of doing this with a pivot table. Also I could achieve something similar with a countif type command and run it from a static calendar type table (which is what I'll probably end up doing if this ends up being a dead end).
As a solution, you can copy the pivot table and paste it as values in the new sheet. Do you math on values instead of on pivot.
I don't know if formatting your results in the pivot as NUMBER would help.. But you can try that as well.
I was unable to determine a way outside of what was mentioned above by Andrew. I've set up a static date list for the calendar month and then use a series of countifs instead of a pivot table to generate the output. Thanks to all who reviewed the question and to Andrew for his responses.
I would like to create an end report, which shows a calendar(month) with aggregation for the specified data.
I am working on cognos 8.4, I have a requirement where I have to show the statistics of the month in a calendar form. The report should be dynamic and it should display the details of the particular month.
Any help or advice is highly appreciated.
Have you tried creating a crosstab? I would create an SQL view of your data to get something like this:
select amount, DayNumber, DayofWeek, MonthName, MonthNumber, YearNumber, Weeknumber
from your_view
Within Report Studio filter on YearNumber and MonthName (ordering by Monthnumber). Then create a crosstab where columns would be DayofWeek and rows would be Weeknumber. Inside the crosstab drag the amount field.
Remember Cognos auto-sumarize everything by default unless you override that behavior.
One thing I cannot think to figure it out is how to display the DayOfMonth within the crosstab. That one is tricky since the data is string and it is not groupable in any calculation (MAX, SUM, AVG, etc). If you can find a solution for that, please let me know. Cheers.
You can use a repeater table, and the table will use a query which gives you the dates, you can apply the filter in that query for the user-selected month. After you have that part working, you can pull a list into the repeater table and then use master-detail relationship from the date query to the list query, then you can design your list inside the table.
