I have a package in SSIS when I have a start date with a parameter:
However I have a query then use that parameter, but I need to have de previous day here:
for exemple if start_date is '2022-03-03' I need to set up #SDATE to '2022-03-02'.
Can anyone help me. Thanks
This will give the previous date of the date in question :
(DT_WSTR, 10) DATEADD("day",-1,start_date)

How can I write an SSIS expression that determines whether a date is a weekend day?
I have this expression, but it seems it only 'works on my machine'
DATEPART( "Weekday", #[User::CurrentDate] ) ==6 || DATEPART( "Weekday", #[User::CurrentDate] ) ==7
After I deploy SSIS package to server, is suddenly changes order of numbers and
Monday became 2.
When on my computer Monday is 1, exactly as I expected.
I checked SQL Server itself, but it seems is something inside SSIS decide if Sunday or Monday is first day.
I cannot find exact question related to this issue.
Well, if you must do this in an SSIS expression, here is one way to work around the problem: you would compare the DW of your variable to the DW of a known constant (like August 3, 2019, which is a Saturday in any locale that I know of).
In pseudocode, IF ( DW(DateVariable) = DW("20190803") OR DW(DateVariable) = (DW("20190803")+1)%7 ) THEN {DateVariable is a weekend}
Personally, I would look for a way to do this in TSQL. Import the raw data "as is" into a staging table, and then do the transformation while moving the data to the destination table with a stored procedure.
DATEPART("DW",GETDATE()) or DATEPART("WEEKDAY",GETDATE()) works perfectly fine on both SQL server and local.
How are you passing value to #[User::CurrentDate] variable(Please check if same date is set when packages is executed on SQL server and on local)
I changed DateTime on my local and tested your expression as part Of Execute SQL task and Derived Column Transformation which gives me 1 for Sunday, 2 for Monday and so on and the result matches with SQL.
SQL query to get day of week:
SELECT GETDATE() Today,DATENAME("DW", GETDATE()) DayofWeekToday,
DATEPART("DW",GETDATE()) DayNumberToday,GETDATE()-1 Yesterday,
DATENAME("DW", GETDATE()-1) DayofWeekYesterday,DATEPART("DW",GETDATE()-1) DayNumberYesterday
Adding more to my answer : There is a difference between DateFirst and DatePart. DateFirst sets first day of the week while Datepart gives you day of the week. use this sql function to check what's your first day of the week
Set Datefirst 7 -- To set first day of week (7 = Sunday)
SELECT ##DATEFIRST -- To check first day of week
**Update your system settings to match first day of the week with sql server and you should get same values when you evaluate expression.
Your expression looks good its only your first day of week on local and sql server are not matching.
Once I updated first day of week on SQL, I was able to replicate the issue you are facing.
I've built an SSIS package that runs on schedule weekly on Mondays. It looks for a .csv file that has a date at the end of the file name, which is 2 Saturdays ago from the date it runs (on Mondays). I need the variable to default to two Saturdays ago. Example: SSIS job runs on 7/9/2018, it needs to set it to 6/30/2018. SSIS needs to be runnable in case of failure, so if it has to be run again on, for example, 7/11/2018, it needs to default to 6/30/2018. This is a weekly job scheduled to run on Mondays.
I found a question posted similar to my need and the link is below for additional reference.
SSIS expression previous date without DateAdd()
I just figured out how to format the date extension as 'mmddyyyy' inside Expression Builder for the variable. Below is my code.
RIGHT("0" + REPLACE((DT_WSTR, 30) (DT_DATE) DATEADD("Day", 7*(DATEDIFF("Day", (DT_DATE)0, GETDATE())/7-1), (DT_DATE)0),"/",""),8)
any advice appreciated
I have as a column heading the expression =WeekdayName(weekday(fields!date.value))
This returns the day of the week, however, it is returning a day of the week one day in advance, eg when I put Monday's dates in the parameter it shows as 'Tuesday' in the report.
My question is can the above expression be tweaked to show the WeekdayName one day before, eg =WeekdayName(weekday(fields!date.value -1)) ? I tried this but got an error.
Thanks.
So you want to subtract one day from the your incoming date then you can use the
= DateAdd("d", -1, yourdateField)
This way you can subtract the any number of days from your date.
But did you try to see why it is giving the day of previous date. Do check the system date time or else check with the
=WeekdayName(weekday(Today()))
and see if it gives you the correct day of week for current date.
Weekday and weekdayname functions have both another optional argument for defining the starting day of the week.
Problem is the 2 functions don' t default this argument to the same value so depending on your server settings you should explicitly set the second argument of these functions.
No need to invoke a date function. As the weekday() function returns and integer you can offset the result and use the Mod operator to keep it in bounds:
=WeekdayName((weekday(fields!date.value)+5) Mod 7)+1)
The parenthesis are important to ensure the addition comes first.
Just for reference:
OP asked again because of the weekday offset and this is the correct provided solution.
=WeekdayName(weekday(Today())) gives me tomorrow
=WeekdayName(Weekday(Today(),FirstDayOfWeek.System))
I want to find out the day of the week from date in ssis.
Actually i want to move the data from one server to another,
In the source server there is one cloumn reportdate having the previous date,so while i wan to copy in to the destination server wan to insert todays date,but there is one case like there is no data comes on sunday in the source server in that case i will have the data of saturday so in this case i want to update the date in the destination server with 2 days plus,please let me know how can i reslove this using ssis.i'm using derived column for manipulating the date column DATEADD("day",2,reportdate) : DATEADD("day",1,reportdate),
so first part will update the date plus 2 of the sourcedate into the detsination table date but how will i find the day of week means when the saturday comes...please let me know how can i reslove this using ssis.
Thanks is advance..
Try this :
DATENAME(weekday, GETDATE())== "Sunday" ? DATEADD("day",2,reportdate):
DATEADD("day",1,reportdate)
Use GETDATE() else use DATEADD(day,-1,reportdate) in the above expression
Update :
Use DATEPART in SSIS
DATEPART( "Weekday", getdate())
Expression is
DATEPART("weekday", GETDATE()) == 1 ? DATEADD("day",2,getdate()):DATEADD("day",1,getdate())
The above expression works in my system having SSIS 2008
I have a report that has parameters StartDate and EndDate. I would like the EndDate parameter's time part to default to the end of the day when selected from the drop down.
For instance, if a user selects 5/15/2008 from the dropdown, the value shown in the box should be '5/15/2008 23:59:59' not '5/15/2008 12:00:00'
Its pretty easy to do this in .Net using the event model and a line of code but in Report Builder 2.0, what would I need to do?
Is there code that I need to write for this or did I miss some funky expression that could handle this?
Thanks.

I would suggest setting the default parameter in the Report Parameters section. You can get to this from Report > Report Parameters.
This allows you to set a non-queried default. There you can enter an expression like
=DateAdd(Microsoft.VisualBasic.DateInterval.Second ,-1,dateadd("d",1,Today))
That should give you a default for the end of today.
Edit: Really only useful for a single default value.
It's been awhile since I've used SSRS, so bear with me. You'll have to do a little translation, but here's what I've done in the past.
When you define your EndDate parameter, create an additional parameter named EndDateEOD, after EndDate in your list of parameters. Make this parameter a hidden value, and set it to the last moment of the day, similar to the way that Jeremy calculates it.
Then you can use #EndDateEOD in your report query where you have #EndDate now.
When StartDate is selected, you could have EndDate default to its value, so that EndDateEOD will automatically be set to the end of the start date.
Use the parameter in a DATEADD() expression in your dataset.
Rather than
...WHERE end_date = #end_date
do something like this:
...WHERE end_date = DATEADD(ms, -3, #end_date + 1)
That will go forward a day (the +1), then go back 3 milliseconds, to the last instant of the day recordable by a datetime.
You can do something like this:
=CDate(Parameters!StartDate.Value + " 23:59:59")
The part of Parameters!StartDate.Value can be any date but not the EndDate.Value itself. Eg:
- Today()
- Last day of the month from start date:
=CDate(DateSerial(Year(Parameters!StartDate.Value), Month(Parameters!StartDate.Value) + 1, 0)+" 23:59:59")
Hope this help.
