Integration Services :: Using Sensitive Project Parameters In Data Flow Tasks
Feb 11, 2014
I have a requirement to read an encrypted file as a data source. I am not allowed to save an unencrypted text file version on disc at any time for any length of time, therefore I created a custom source component that reads an encrypted csv file, decrypts it, and then passes each row of data to the pipeline and ultimately to an ole data destination. Basically it is just a text file reader with an added class that adds functionality that decrypts the file before the component sets columns or reads rows.
The custom component, “Encrypted File Source”, has a custom property “encryptionkey” with the encryption required flag set to true (code below) and is declared as eligible to be set in the expressions.
IDTSCustomProperty100 EncryptionKey = ComponentMetaData.CustomPropertyCollection.New();
EncryptionKey.Name =
"EncryptionKey";
EncryptionKey.Description =
"Secure String key value to decrypt the file";
EncryptionKey.Value =
string.Empty;
EncryptionKey.ExpressionType =
DTSCustomPropertyExpressionType.CPET_NOTIFY;
EncryptionKey.EncryptionRequired =
true;
I want to be able to set the password for the encrypted file in the SQL Agent job that executes the SSIS project. This means I have an environment with a variable, “DataPassword”, that is set to sensitive. It maps to a Project parameter in the SQL Agent job that is also set to sensitive. And I now I want to access that sensitive Project Password inside my data flow, specifically in the Encrypted File source task that I created and set my EncryptionKey to that Project Parameter.
The problem is that SSIS says.
"expression cannot be evaluated. ... The Expression will not be evaluated because it contains sensitive parameter value "$Project::DataFilePassord" . Verify that the expression is used properly and that it portects sensitive information"

I am using SQL Server 2012, on a windows 7 box with VS2010 premium.
I am wondering if it is possible to use SSIS to sample data set to training set and test set directly to my data mining models without saving them somewhere as occupying too much space? Really need guidance for that.
Would please any expert here give me any guidance about what Data Mining tasks can be automated and scheduled via Integration Services Packages? Also, If we automated the tasks, can we also automatically save the results of the tasks somewhere? Like if we automate assessing the accuracy of a mining model, then we wanna know the mining model accuracy later, therefore, we need to save all these results from the automated actions. Is it possible to realize this?
Thanks a lot in advance for any guidance and help for this.
when executing my data flow package that contains only one source and one destination
OLE db source -> SQL server destination
the following errors occurs in my output
Error: 0xC0202009 at Data Flow Task(infraction action), SQL Server Destination [3600]: An OLE DB error has occurred. Error code: 0x80040E14.
Error: 0xC0202071 at Data Flow Task(infraction action), SQL Server Destination [3600]: Unable to prepare the SSIS bulk insert for data insertion.
Error: 0xC004701A at Data Flow Task(infraction action), DTS.Pipeline: component "SQL Server Destination" (3600) failed the pre-execute phase and returned error code 0xC0202071.
i've checked the structure of my source and destination table but nothing seems to be wrong
if someone have ever faced these errors help me :D
Dear All! My package has a Data Flow Task. In Data Flow Task, I use a Script Component and a OLE BD Destination to transform data from txt file to database. Within Data Flow Task, I want to call File System Task to move file to a folder or any Task of "Control Flow" Tab. So, Does SSIS support this task? Please show me if any Thanks
We are using an OLE DB Source for the Data Flow Source and OLE DB Destination for the Data Flow Destination. The amount of data being moved is about 30 million rows, and it is gather using a sql command. There is not other transformations in between straight from one to another. The flow starts amazingly fast but after 5 million rows it slows considerably. Wondered if anyone has experienced anything similar with large loads.
in order to maintain a deployed project into an Integration Services Catalog I'd like to know if it is possible to import it into a new project inside SSDT.
I've got an SSIS solution file with project deployment model in VS 2013 and would like to deploy that to SSISDB on different environments.All these days I followed the regular way to create a project in SSISDB and deploy it to that. Now want to find out if i can automate this process and so got some questions
1. Can we automate the process of creating a project on SSISDB based on our SSIS project name? This will be like when we do a deployment it should check if the project exists or not on SSISDB based on our SSIS project name, if the project exists we just deploy the packages in the project and if the project does not exists in SSISDB it will create that project and deploy the packages.
2. Can we also automate the process of creating environments? In traditional way we manually create the environment variables under environment tab of SSISDB, but can we make that also as part of deployment? Like when we are releasing to Dev server we look if that particular Dev variable exists on that server, if it exists we just update the existing stuff and if it does not exists we just create it.
I have visual studio 2005 and sql server 2005 with integration service installed on my machine. Couple of days ago, I installed visual studio 2008 professional. When I go to create SSIS project I dont see it in visual studio 2008. What do I have to do to make it appear in visual studio 2008 so that I can create SSIS projects.
Data flow A take data from the Excel File A, Data B from Excel File B, Data C from Excel File C. What I'd like to do is that if something goes wrong on Data Flow A I would be alerted but the package should continue to running. The same for the DataFlow B, if A it's ok go on, if B fail send me the mail but continue until the end (so running the Data Flow C).
In my SSIS Data Flow Task, I have a query that retrieves data based on a couple of date parameters. Is there a way we can pass/use the Variables defined in the SSIS package in the query ?
(I am assigning values to those variables from C# code)
The query should look like this:
select ordernumber, customerid from salesorder
where statecode=3 and datefulfilled between @variable1 and @variable2
I have a Data Flow Task within a ForEach loop container. The source of the flow is ADO.NET connection and the destination is a Flat File Connection. I loop through a collection of strings in the ForEach loop. Based on the string content, I write some data to the same destination file in each iteration overwriting the previous version. I am running into following Errors:
[Flat File Destination [38]] Warning: The process cannot access the file because it is being used by another process. [Flat File Destination [38]] Error: Cannot open the datafile "Example.csv". [SSIS.Pipeline] Error: Flat File Destination failed the pre-execute phase and returned error code 0xC020200E.
I know what's happening but I don't know how to fix it. The first time through the ForEach loop, the destination file is updated. The second time is when this error pops up. I think it's because the first iteration is not closing the destination file. How do I force a close of the file within Data Flow task or through a subsequent Script Task.This works within a SQL 2008 package on one server but not within SQL 2012 package on a different server.
I am using the SharePoint adapters from Codeplex that allow me to use SharePoint source and destination tasks in SSIS for SQL Server 2008 and SharePoint 2010. I am able to pull the data from the SQL Server and insert it into the SharePoint List.
However, I prefer to just have fresh data every time, so I'd like to add a step to delete all the items in the list before inserting the new ones. Is there a way I can configure the SharePoint SSIS destination task to clear all the items before I insert new ones?
Using SSIS 2012 (within Visual Studio) on Windows 7.
Before allowing my Data Flow task to fire, I'd like to check the target table (OLE DB Destination) for a specific date value in a specific field. I've seen how the Lookup Task is commonly used to check for dupes before inserting, but I'm not able to use that method because the data value I want to search the table for is contained in a Global Variable (let's say "MyVariableDate").
Is there any way to check for any records in a target table where Date1 = MyVariableDate (i.e. scanning the entire table for any occurrence of MyVariableDate in the Date1 field)?
I have created an event that contains a Data flow tasks with OLE DB source & Excel Destination.
This event is executed/triggered based on an execute SQL task failure in the control flow Sequence container.
However, when I execute the Data Flow task of the Event Handler, it runs successfully but fails when I execute the whole package.
I get the below error message:
[OLE DB Source [21]] Error: SSIS Error Code DTS_E_CANNOTACQUIRECONNECTIONFROMCONNECTIONMANAGER. The AcquireConnection method call to the connection manager "TK463DW" failed with error code 0xC0202009. There may be error messages posted before this with more information on why the AcquireConnection method call failed.
I have tried setting the property 'DelayValidation' to 'True' on all the Control Flow and Data Flow tasks on the package and on the Event Handler, but still I could not fix this.Not sure What I am missing.
I recently upgraded to on 2012 SP1 CU5 and have found the SSDT gui for SSIS to be almost unusable. I can't drag or resize items. Any time i try they either automagically shrink to the tiniest possible size, shoot off to some extreme or just shake uncontrollably I didn't have these problems on previous versions (dont remember what It was).
I have huge data and i am loading data from EXCEL to database table, after loading 80 percent data i am getting some error. My package got failed and it has lots of transformation and took around 6 hours to process completely because of that i don't want it to reload from start. if i run it again it should start from next record from where i got the error.
We have a single generic SSIS package that is used to import several hundred iSeries tables into SQL. I am not looking to rewrite the process. But I am looking for ways to improve performance.
I have tried retain same connection, maximum insert commit size, lock table (tablock), removed some large columns, played with the log file location and size, and now I am working to tweak the defaultbuffermaxrows.
To describe the data flow task - there are six data flows tasks (dft) working at the same time. Each dtf has their own list of iSeries tables and columns and the corresponding generic SQL table names. Each dtf determines their list of tables based on the number of columns to import. So there is dft30 (iSeries table has 1-30 columns to import), dtf60 (iSeries table has 31-60 columns to import), etc. The destination SQL tables are generically called Staging30, Staging60, etc. Each column in the generic Staging tables are varchar(100). The dtfs are comprised of an OLE DB Source and an OLE DB Destination.
The OLE DB Source uses a SQL Command from Variable to build a SELECT statement. The OLE DB Source uses a connection manager that uses an IBM iAccess IBMDA400 provider. The SQL Command ends up looking like this for the dtf30. This specific example is importing from the iSeries table TDACLR and it only has two columns so it will be copied to the Staging30 table.
select TCREAS AS C1,TCDESC AS C2,0 AS C3,0 AS C4,0 AS C5,0 AS C6,0 AS C7,0 AS C8,0 AS C9,0 AS C10,0 AS C11,0 AS C12,0 AS C13,0 AS C14,0 AS C15,0 AS C16,0 AS C17,0 AS C18,0 AS C19,0 AS C20,0 AS C21,0 AS C22,0 AS C23,0 AS C24,0 AS C25,0 AS C26,0 AS C27,0 AS C28,0 AS C29,0 AS C30,''TDACLR'' AS T0 from Store01.TDACLR
The OLD DB Source variable value looks like the following, but I am not showing the full 30 columns
select cast(0 AS varchar(100)) AS C1,cast(0 AS varchar(100)) AS C2,cast(0 AS varchar(100)) AS C3,cast(0 AS varchar(100)) AS C4,cast(0 AS varchar(100)) AS C5, ... cast(0 AS varchar(100)) AS C30.
The OLE DB Destination uses OpenRowSet Using FastLoad From Variable. The insert into Staging30 ends up looking like this.
Of course we then copy and transform the Staging30 data to the SQL table that equals T0.
But back to defaultbuffermaxrows. Previously the dtfs had default values of 10000 for DefaultBufferMaxRows and 10485760 for DefaultBufferSize. I added a SQL task to SUM the iSeries column sizes, TCREAS and TCDESC in this example, and set the DefaultBufferMaxRows by dividing the SUM of the columns max_length into 10485760. But I did not see a performance improvement. Do you think that redefining the columns as varchar(100) for the insert is significant? Should I possibly SUM the actual number of columns (2) as 2x100 or SUM the 30x100?
Basically i'm trying to create an SSIS workflow to download Sharepoint List data to SQL Server on a schedule of some kind.do we actually have to use the GAC install approach in order to get the Sharepoint List Destination and Sharepoint List Source entries to appear on the SSIS Project workflow entities?
I'm trying to edit the Expressions of a Data Flow task. This seems to happen when I rename some of the Data Flow components but not always. The error I get is:
Element "[ADO Net Source].[SqlCommand]" does not exist in the collection "Properties"
However, if you look at the XML, this property does exist. So I'm not sure why this should occur.
I'm using SSIS 2008 R2 with Visual Studio 2008 V 9.0.30729.4462 QFE.

We have created SSIS package to load a text file into a table. Source system shares 10 text files and recently they stopped generating data for one of the text file (comping empty), after few months they will start generating the data for the empty file batch processing.
The Issue here is Data Flow task is getting failed while loading empty text file into table. How to handle this empty file load issue in SSIS package.
When I copy over an SSIS package I have been developing from my laptop to my desktop with Windows File Sharing (shared folders) across a home network, the moved package fails to load properly. I can see the Control Flow tasks but not the Data Flow tasks - they simply disappear! I have update the Connection Managers to point to the new machine, and tested them (OK).
Its the same as this issue posted here
And Here
Creating an empty package and clicking to create a new data flow cause this error:

Seems the only way is to uninstall and reinstall Client Components.
How do I uninstall and reinstall Client Components? when I try to do that, SQL Server Setup tells me "None of the selected features can be installed or upgraded. Setup cannot procees since there is no effective change being made to the machine...."
I had selected "Workstation components, Books online and Development tools". This is already installed - so how I can reinstall it if I get this message above which does not let me proceed.
I have created around 10 seperate packages for our application data load. Now I am planning to create a master package (or a wrapper package) which will execute all the 10 packages (thru execute package task). Then I have a job which executes the master package at a given date and time.
Question : How can I enable / disable execution of each package within the master package depending upon a flag variable. The reason why I need this mechanism is if the flag = 0 then I don't want all 10 packages within master package to execute and if flag = 1 then master package execution should begin and subsequently execute all packages within that master package.
i got a foreach loop that has about 20 data flow tasks(same database connections but different extractions) but i notice that when i execute the project it only runs 4 data flow tasks at a time.
i know that there is an option for each data flow to set the "Engine Threads", but is there a way to set the thereads in a foreach loop or for the whole project so it will execute all data flow tasks in one go for each loop.
i have a for each loop and it has about 20 data flow tasks (simple data extractions). i notice when i run the package it only runs up to 4 data flow tasks at a time. others have to wait till one of the first 4 flows finishes.
i was wondering if there's a way to change the limit of how many data flow tasks can run at a time. is there a property some where ?
i know this will be stressfull to the server, but the server is well equiped with CPU power and memory, so performance will not be an issue.
Hey all, is there any explanation why just opening a data flow task causes a VSS check out?
The issue with this is that I have multiple developers, and when one wants to look at a data flow task in a package already checked out, it generates multiple VS errors.
Not big on the priority list, (not as big as the modal dialog issue) but still a pain.
I am facing an issue that Data flow task failing after loading 29000 rows out of 2lakhs rows.
I am loading data from .csv file to OLE DB Destination.
This data flow task is placed inside For each loop container.
is this issue because of any performance issue in SSIS packages such as buffer size.
find the error below:
DFT Load Data from FlatFile:Error: The conditional operation failed. DFT Load Data from FlatFile:Error: SSIS Error Code DTS_E_INDUCEDTRANSFORMFAILUREONERROR.
The "DER Add Calc Columns" failed because error code 0xC0049063 occurred, and the error row disposition on "DER Add Calc Columns.Outputs[Derived Column Output].Columns[M_VALUE_NUM]" specifies failure on error. An error occurred on the specified object of the specified component. There may be error messages posted before this with more information about the failure.
DFT Load Data from FlatFile:Error: SSIS Error Code DTS_E_PROCESSINPUTFAILED. The ProcessInput method on component "DER Add Calc Columns" (48) failed with error code 0xC0209029 while processing input "Derived Column Input" (49). The identified component returned an error from the ProcessInput method. The error is specific to the component, but the error is fatal and will cause the Data Flow task to stop running. There may be error messages posted before this with more information about the failure.
I need to parameterize some values in the data flow so that i can chnage the values directly in parameter file and re run the data flow for new value in the passed in the parameter. This can be easy for other who do not know about the flow of data flow task as to where to change the variable/parameter.
How can this be accomplished. I want the data flow task to refer to this file before it starts executing and pick the appropriate value from the file.
Or is their any better way to accompalish what i want to do here in SSIS.???
