I have filter for my dataset:
Keep rows where date is on or after $filter_date
Can I set parameter $filter_date to be 60 days (or 8 weeks or 2 months) away from today?
Great question!
You can use an expression paired with a dynamic parameter as such:
date_diff(current_date(), date1) <= $number_of_days
You can read more on the date/time functions here:

i need to create parameter list of months and then (after select) recalculate two others paramateres in date format ([first day] and [last day]) of this month, can you please help me?
You are querying a database server to generate the list of months, although there's no need to do that. I suggest to rather create a list of months in the report and let the report calculate the month's names, so the language depends on the Language setting of the report (which can be the language configured in the user's browser).
For example, to calculate the Label for the Value 1, use an expression like =MonthName(1).
The Parameters FirstDay and LastDay (or just the values whenever you need them) can be calculated using these expressions:
FirstDay: =DateSerial(Today.Year, Parameters!Month.Value, 1)
LastDay: =DateSerial(Today.Year, Parameters!Month.Value, 1).AddMonths(1).AddDays(-1)
I am struggling making sense of the TIMESTAMPDIFF() function using MYsql
here is an example:
SELECT TIMESTAMPDIFF(minute,start_time,end_time) AS Duration
FROM exam_answers
LIMIT 200;
Can someone explain to me what this is doing and what the purpose of me using it is? is their easier code? is this commonly used in business settings?
Thanks.
All this is doing is running a calculation on two fields in your data. So the function is returning the difference between the second and third parameters in the units defined by the first parameter.
TIMESTAMPDIFF(DAY, '2011-12-10', '2011-12-20')
will return 10. Because there are 10 days between Dec 10th and Dec 20th. That value is retrieved as Duration (just an alias).
I'm fairly new to reporting and need help with the following?
I have a report that has two date parameters statically set to default to the last financial year. i.e. the FROM parameter 01/04/2015 and the TO parameter 31/03/2016.
When the actual date next year is 01/04/2017 I need these parameters to change forward by one year, I know I maybe able to do it with a case statement and a getdate + dateadd .
I have a small table which creates a year period based on certain dates which I then join onto the data then I use that to filter.
for instance:
1516
1617
1718
so if #year_period = 1516 then the previous year would simply be #year_period-101 and the future would be #year_period+101
I am facing issue in calculating past 5 week data based on current date (excluding currrent week)
For e.g:
Suppose we are in 40th week of this year, I need to get the sum of all the transactions for the previous 5 weeks (39, 38, 37, 36 & 35).
Currently calculating based on the calendar day but as Calendar day is giving the granular level of data, inorder to increase the performance I need to use the calendar week (sample data like (2012/40).
Is there a way to do this?
I'd construct a flag field (either in the back-end or in the universe) using datediff (in SQL Server terms).
Failing that, you could construct a variable in Web Intelligence using the Week function.
Pseudo-code but something like:
=IF(Transaction_Date < Week(CurrentDate()) AND Transaction_Date >= (Week(CurrentDate())-5); "TRUE"; "FALSE")
I need current month name as default perameter name in my ssrs report. How can I get current month name using an ssrs expression?
For example "27-09-2012" would become "September"
and one more i need....
27-09-2012 to previous month name as well (August)
First question:
=MonthName(Month(Fields!datefield.Value))
Second question:
=MonthName(Month(DateAdd("m", -1, Today())))
I think the second question answer might be something like that, first converting the date to month then subtracting 1 from the month value and then converting it to month name.
Further reading:
SSRS Reports get Month name from Month Index or from date

OFF: I would change the date format you are using to 2012-09-27 as it works in every setting and should give you peace of mind when converting date formats.
Don't subtract 1 b/c it won't work for January.
Use this:
MonthName(Month(DateAdd("m", -1, CDate(Today))))
As a note, I tried the suggestion of =MonthName(Month(today())). What I would get is #error for whatever field the expression was in. However, =MonthName(str(Month(today()))) worked for me. I am unsure of whether or not the MonthName method changed to require a string or if it is some issue with my program. Just figured I would post this in case anyone else was having the same issue.
For Previous Month i found universal way : =MonthName(Month(CDate(Today()))-1,False) for SEPTEMBER (Full Month Name) 'OR'
=MonthName(Month(CDate(Today()))-1,True) for SEP (Short Month Name)
