I'm trying to construct an SSIS package where one of the columns is a DT_DBDataTimeStamp format.
My problems is that I have to convert this to a DD/MM/YYYY format and I can't use a C# script.
I'm trying to use a derived column by having difficulty in getting the correct format.
I've tried Convert(varchar, Date_Column, 103) - doesn't work.
I've tried DAY(Date_Column) + MONTH(Date_Column) + YEAR(Date_Column) - doesn't work.
Anybody know how I can do this?
It would need to be varchar if you want this (actually, I will use nvarchar for simplicity):
right("0" + (DT_WSTR,2) day(Date_Column), 2) + "/" +
right("0" + (DT_WSTR,2) month(Date_Column) , 2) + "/" +
(DT_WSTR,4)year(Date_Column)

I need to achieve the date format yyyy-mm-dd conversion on SSIS
I tried the below code but I keep getting error:
year and posting_period is a varchar(50) on my source data.
Sample data on my source:
year = 2014
posting_period = always 2 digit
What did I miss in my codes below?
(DT_DBDATE)((DT_WSTR,4)year + "-" + (DT_WSTR,2)posting_period + "-" + "01")
You need to set the variable's data type to datetime; encapsulate the string in parenthesis; and cast it as DT_DATE:
(DT_DATE)(#[User::Year] + "-" + #[User::posting_period] + "-01")
To my knowledge, you cannot specify how the datetime is displayed. So, this will evaluate to MM/DD/YYYY, which is fine. You should not worry how the date is formatted in the database. You should only care about how it is displayed in the reporting tool, which typically allows you to convert or cast the date in many different ways.
I'm a bit of an SSRS newbie and I'm having some trouble converting an Int to a Date in SSRS. The publication_date.Value is fed from a proprietary database as an Int type (so we unfortunately have no control over that) in the format 20160519.
The following works splendidly when there is a value present:
=CDate(Left(Fields!publication_date.Value, 4) + "-" + Mid(Fields!publication_date.Value, 5, 2) + "-" + Right(Fields!publication_date.Value, 2))
However, when there is a null it returns an #Error, which I'd like to suppress. I've tried using an IIf statement but without success.
=Iif(Fields!publication_date.Value is nothing,"", CDate(Left(Fields!publication_date.Value, 4) + "-" + Mid(Fields!publication_date.Value, 5, 2) + "-" + Right(Fields!publication_date.Value, 2)))
I've been digging around for other solutions but yet to find anything that works. Please help!
Edited - thanks for the duplicate article suggestion, however I need to convert an Int to a Date and handle the errors, not a Date to an Int.
I had the same issue,
As per your example, do one thing.
Keep you expression same like below,
=CDate(Left(Fields!publication_date.Value, 4) + "-" + Mid(Fields!publication_date.Value, 5, 2) + "-" + Right(Fields!publication_date.Value, 2))
Now, tricky part would be, in textbox visibility use below expression.
=IIf(IsNothing(Fields!publication_date.Value),True,False)
It will definitely work. Let me know if you face any issue. Thanks.
I am in the process of uploading the delta load to a CSV file. I have set up a conditional split in the package which will compare the last modified date with the below expression:
RIGHT("0" + (DT_STR,2,1252)DATEPART("dd",GETDATE()),2)
I need to replace above with:
(DT_STR,2,1252)DATEADD("dd",-1,GETDATE())
But it is throwing a warning error message. The package is failing.
The only possible thing you can replace with that second expression is your GETDATE() method. More precisely, you are probably trying to retrieve the previous day based on your second expression.
From:
RIGHT("0" + (DT_STR,2,1252)DATEPART("dd",GETDATE()),2)
Replaced:
RIGHT("0" + (DT_STR,2,1252)DATEPART("dd",DATEADD("dd",-1,GETDATE())),2)
Example:
Reading from a flat file that has a column containing the year and month in the following format --> "201212".
I need to insert this into a DATETIME2 column but first I must parse it with "/" and add a "01" as the day. Such that 201212 would become 2012/12/01
My expression in my Derived Column Transformation looks like this:
(DT_DBTIMESTAMP2,0)((DT_WSTR,4)SUBSTRING(RptMthDTM,1,4) + "/" + (DT_WSTR,2)SUBSTRING(RptMthDTM,5,2) + "/" + "01")
This seems like it should work and SSIS accepts this(as in it can parse the expression) but when running the package it throws a completely useless error "An error occurred while attempting to perform a type cast." along with the column it had the error on.
I didn't build this package, it was pawned off on me and I was told to get it working.
Thanks in advance interwebs family.
DT_DBTIMESTAMP2 can only be converted from a specific string format: yyyy-mm-dd hh:mm:ss[.fffffff]
You can use this expression instead:
(DT_DBTIMESTAMP2,0)((DT_WSTR,4)SUBSTRING(RptMthDTM,1,4) + "-" + (DT_WSTR,2)SUBSTRING(RptMthDTM,5,2) + "-" + "01 00:00:00")

I would like to create random unique filename in SSIS using expression builder for Flat file connection Manager - ConnectionString.
Should be like: "Custom name" + "unique part" + "csv"
Actualy a timestamp in miliseconds would do.
Any idea?
I suggest you using the expression design to do that.
Here Im using the ExecutionGuid to generate the value. It may not be the best idea because the result is quite big but you can use datetime functions as well to create something on the format you desire:
It's a litte convoluted thanks to all the REPLACEs, but you can use:
"Custom Name " + SUBSTRING(REPLACE(REPLACE(REPLACE((DT_WSTR, 50)(GETDATE()), "-",""), ".", ""), ":",""), 1, 18) + ".csv"
as a starting point. This will return:
Custom Name 20120529 133526359.csv
as a possible filename. It's not 100% guaranteed unique, and it's obviously not random, but I think it's all that can be done just in an Expression. Alternatively, you can use a Script Task to generate a more random string using C#/VB.NET, write that into a variable and use the variable in your Expression.
string.Format("Custom name{0}.csv", Path.GetRandomFileName());
or
string.Format("Custom name{0}.csv", DateTime.Now.ToString("yyyyMMddhhmmssfff"));
This will be to get unique date time..
" + (DT_WSTR, 30)(DT_DBDATE)GETDATE() + "_" +
(DT_WSTR, 05) DATEPART("Hh",GETDATE()) +
(DT_WSTR, 05) DATEPART("Mi",GETDATE()) +
(DT_WSTR, 05) DATEPART("Ss",GETDATE()) +
".csv"
I found that it was easy to find how to create the expression but difficult to find instructions on how to set your output filename to use this expression. It is not a straightforward process. Here is an answer to this problem. I hope this helps somebody.
