I have an SSIS package that runs each morning to pull the previous days file from an FTP server. I am using the code below to create the file name using the previous date. Everything works great with this except when today's date is the first day of the month. for example, if ran today (3/1/2021) this returns name_of_file_20210328.xml.gz, however yesterday's date is 2/28/2021 not 3. How do i update this to say if today's date is beginning of month return mm - 1?
"name_of_file_" + (DT_STR,4,1252)(DATEPART("yyyy",GETDATE())) + (LEN((DT_STR,2,1252)(DATEPART("MM",GETDATE()))) == 2 ? (DT_STR,2,1252)(DATEPART("MM",GETDATE())) : "0" + (DT_STR,2,1252)(DATEPART("MM",GETDATE()))) + (LEN((DT_STR,2,1252)(DATEPART("dd",DATEADD( "day",-1, GETDATE())))) == 2 ? (DT_STR,2,1252)(DATEPART("dd",DATEADD( "day",-1, GETDATE()))) : "0" + (DT_STR,2,1252)(DATEPART("dd",DATEADD( "day",-1, GETDATE())))) +
".xml.gz"
Create a variable, Yesterday of type DateTime. Specify that it uses an expression and use the following expression. This provides a consistent reference point you can test against and if you disable the expression, allows you to specify a date for boundary/special case checking (like a leap year 2020-03-01)
DATEADD("DAY", -1, #[System::StartTime])
The next steps, especially if you're starting out, is to build the date parts in separate variables. It doesn't cost any extra to use lots of variables in your package and makes troubleshooting so much easier.
Add a new variable, YearString of type String.
(DT_WSTR, 4)datepart("YYYY", #[User::Yesterday])
That was easy.
Now we need to deal with create a zero, left padded string. Right now, your expression looks like it's trying to determine if day or month has 2 digits. I have a cleaner expression.
We're going to convert the day/month to a string and then prepend a zero to it. For Jan-Sep, we'll end up with a 2 character expression, Oct-Dec, we'll have a three character expression e.g. 011. For Day, similar bit where it's 01-09 or 010-031. We will then take the last two characters from the string. For the two character strings, it's a no-operation and for the three character variant, it gets us what we want.
Add Variable MonthString, as type string, to your package
RIGHT("0" + (DT_WSTR, 2)datepart("MONTH", #[User::Yesterday]), 2)
Add Variable DayString, as type string, to your package
RIGHT("0" + (DT_WSTR, 2)datepart("DAY", #[User::Yesterday]), 2)
Take a moment and look at your Variable collection. You can see that you have all the building blocks needed to properly construct your YYYYMMDD string. If something is wrong, it's small enough snippet to play with it. If not, break it up into smaller Variables.
Now that we have defined #Yesterday and then built YearString, MonthString and DayString off of Yesterday, all we have to do is bring it all together with the concatenation + operator
Back to the Variable well, creating #CurrentFileName of type string
"name_of_file_" + #[User::YearString] + #[User::MonthString] + #[User::DayString] + ".xml.gz"
Results in a value of name_of_file_20210216.xml.gz
Not addressed in this answer but things you should think about
What happens when the job doesn't run at all today (server fails horrifically, the data source is down, etc)? To pick up and process 2 days ago file, you would need to edit this package, run it through whatever change review process is applicable, deploy to prod, run it and then go back to the process yesterday file package.
That's not fun to type much less consider. You certainly aren't going to change the server time to trick the expression into being yesterday.
I am an advocate for passing the run date to the package (mechanism depends on how you deploy/run packages). In that situation, it's been my experience that it's a far easier bureaucracy fight to change the calling parameter (because no "code" has changed) than to get an emergency code change run through.
I am trying to extract a numeric month and date from a give hire date to create an annual anniversary date in report builder.
Thus far I have tried the code below:
=Year(Now) +"-"+ Month(Fields!hire_date.Value) +"-"+ Day(Fields!hire_date.Value)
I got a #Error in the field I am trying to populate.
Looks to me like you're simply using the wrong syntax to concatenate the date. Additionally, you could simplify the expression using FORMAT. Try this:
=Year(Now()) & "-" & Format(Fields!hire_date.Value, "MM-dd")
This should return the date in the format 2019-06-21.
For other ways to format the date, see this link.
Hi I'm trying to build a report in ssrs which gives the output based on current weekending date where end day is saturday. I'm pulling my data from SSAS Cube and I have a weekending date field so I applied a filter in the query designer to get the current weekending date using a parameter I used this expression:
DateAdd("d",7-DatePart(DateInterval.Weekday,Today,FirstDayOfWeek.Sunday),Today)
When I'm executing my query, it throws an error saying the restriction imposed by the constrained flag in the STRTOSET function were violated.
Please let me know how can I fix this.
The error is thrown because you are passing a string that doesn't correspond with a valid member in your cube.
Note the Query Designer builds a MDX query based on the dimensions and members you select, this query uses the STRTOSET() function to convert your string parameter in a valid member.
...
STRTOSET(#CurrentWeekendDate,CONSTRAINED)
...
If you pass the current weekend date to your parameter it produces:
STRTOSET('2016-01-10',CONSTRAINED)
As 2016-01-10 is not a valid member in your Date dimension it throws the error.
You have to pass something like this depending on your cube:
[Date].[Date Key].&[2005-01-01T00:00:00]
So in SSRS you have to set your parameter to Text and use this expression:
CORRECT EXPRESSION:
="[200 Date].[Week Ending Date].&[" &
Format(
DateAdd("d",7-DatePart(DateInterval.Weekday,Today,FirstDayOfWeek.Sunday),Today),
"yyyy-MM-ddThh:mm:ss"
)
& "]"
UPDATE: If [Week Ending date] level doesn't include time:
="[Date].[Date Key].&[" &
Format(
DateAdd("d",7-DatePart(DateInterval.Weekday,Today,FirstDayOfWeek.Sunday),Today),
"yyyy-MM-dd"
)
& "]"
Go through this tutorial if you get stuck.
Let me know if this helps.
I have a report with date and time (only an hour and minutes) parameters which are separate. The Date parameter is of type Date/Time, and the Time parameter is set as Text. I want to merge those two values into one because I want to pass a minimum number of arguments to the stored procedure. I tried to achieve that goal in many ways but SSRS returns an error for every attempt.
If I try to use expression like this:
=Format(FormatDateTime(Parameters!startDate.Value, DateFormat.ShortDate).ToString() + Parameters!startTime.Value, "dd/MM/yyyy HH:mm")
SSRS returns this error:
Error conterting data type nvarchar to datetime.
And when I tried to use Datetime.Parse like this:
=DateTime.Parse(Format(FormatDateTime(Parameters!startDate.Value, DateFormat.ShortDate).ToString() + Parameters!startTime.Value, "dd/MM/yyyy HH:mm"))
SSRS said:
The Value expression for the query parameter '#startDate' contains an error: The string was not recognized as a valid DateTime. There is a unknown word starting at index 0.
When I removed the FormatDateTime function I get yet another error:
The Value expression for the query parameter '#startDate' contains an error: Input string was not in a correct format.
Do you have any ideas how to write this expression correctly?
PS. I use SSRS 2008 R2.
This works for me:
=CDate(Format(Parameters!Date.Value, "yyyy-MM-dd") + " " + Parameters!Time.Value)
Didn't try and troubleshoot your specific examples, but they may be running into issues where you're not including the space between the date and time.
The above expression may be suitable for your report; don't know robust it would be in different locales.
You could also consider doing the concatenation/conversion in custom code if you need more flexibility.
Hi I am trying to use the expression column in flat file connection manager to generate file with dynamic naming e.g
File-ddmmyyyyhhmmss.txt
I understand that I can use getdatepart but what is the exact method call to get the hh, mm and ss? Can anyone advise?
Pragmatic works SSIS Expression Cheat Sheet is a good start. You can expand to your situation by using (DT_WSTR, 2) datepart("HH",getdate()) to get the hour portion, (DT_WSTR, 2) datepart("n",getdate()) to get the minutes and (DT_WSTR, 2) datepart("s",getdate()) to get the seconds. You will need to add logic in to ensure that values less than 10 still get two digits (i.e. 01 05) etc. For Day, month and Year, there are function DAY() MONTH() and YEAR() that shortcut the equivalent datepart() functions.
