How To Retrieve Connections Collection Inside Custom Data Flow Tasks (source/destination)

May 16, 2008


How do I retrieve the connections (connection managers) collections from Custom Data Flow destination? ComponentMetadata.RuntimeConnectionCollection is empty. I would like to be able to access all the connections defined in the package from the custom data flow task.

I came across code in which it was possible to access the Connections collection using the IDtsConnectionService for custom task (destination). The custom task has access to serviceProvider, whcih can be used to get access to the IDtsConnectionService interface but not the custom data flow task.

Any help appreciated.

Data Flow Task - OLEDB Source / Destination

Nov 9, 2006


Inside a data flow task, i have a oledb source and destination. In my situation, I need to pull data from a table in the source, but also hard code some columns myself, which means my source is a blend of data from table, hard coded data, which will then have to be mapped to columns in oledb destination. Does anyone which option to choose in the oledb source dropdown for the data access mode. Keep in mind, i do need to run a a select query, as well as get data from a table. Is it possible to use multiple oledb sources and connect to one destination, because that is really what intend to do here. I am not sure how it will work, or even if its possible. Basically my source access mode needs to be a blend of sql command and table columns, how would that be implemented? Any help or advice is appreciated.

Integration Services :: DefaultBufferMaxRows - Is It Determined By Row Length Of Data Flow Task Source Or Destination

Oct 18, 2015

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.

insert bulk STAGE30([C1] varchar(100) ,[C2] varchar(100) ,[C3] varchar(100) ,[C4] varchar(100) ,[C5] varchar(100) , ...  ,[C30] varchar(100) ,[T0] varchar(20)

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?

Custom Source UI Connections

Jan 12, 2008


I've been fighting a problem all day now. I have given in. I need help.

Here's the problem. I have a SSIS Custom Data Flow Source, for retrieving data from a proprietary data format. The component works great. I can use the Advanced Editor to select the connection to use (also a Custom Connection Manager) and a custom property. The custom property that is the name of a table to select data from.

I am in the process to building a simple UI that has a ComboBox of Connections (by name) and a ListBox of table names available in that connection.

I want to be able to pre-select the connection in the ComboBox if one is already populated. The problem is, I can't figure out how to get access to the connection name of the currently selected connection. When I look at the RuntimeConnectionsCollection[0], that connection is not acquired. I can't get access to the name, or any of its custom properties (see above that connection is Custom also).

Assume I use the Advanced Editor to select a connection to use, then open the custom UI.

How do I figure out what the name of the connection selected is? I know it is possible. The OLE DB Source does it.

Expression Editor On Custom Properties On Custom Data Flow Component

Aug 14, 2007


I've created a Custom Data Flow Component and added some Custom Properties.

I want the user to set the contents using an expression. I did some research and come up with the folowing:

Code Snippet
IDTSCustomProperty90 SourceTableProperty = ComponentMetaData.CustomPropertyCollection.New();
SourceTableProperty.ExpressionType = DTSCustomPropertyExpressionType.CPET_NOTIFY;
SourceTableProperty.Name = "SourceTable";

But it doesn't work, if I enter @[System:ackageName] in the field. It comes out "@[System:ackageName]" instead of the actual package name.

I'm also unable to find how I can tell the designer to show the Expression editor. I would like to see the elipses (...) next to my field.

Any help would be greatly appreciated!

Thank you

Expression Issue With Custom Data Flow Component And Custom Property

Apr 2, 2007


I'm trying to enable Expression for a custom property in my custom data flow component.

Here is the code I wrote to declare the custom property:

public override void ProvideComponentProperties()




IDTSCustomProperty90 prop = ComponentMetaData.CustomPropertyCollection.New();

prop.Name = "MyProperty";

prop.Description = "My property description";

prop.Value = string.Empty;

prop.ExpressionType = DTSCustomPropertyExpressionType.CPET_NOTIFY;



In design mode, I can assign an expression to my custom property, but it get evaluated in design mode and not in runtime

Here is my expression (a file name based on a date contained in a user variable):

"DB" + (DT_WSTR, 4)YEAR( @[User::varCurrentDate] ) + RIGHT( "0" + (DT_WSTR, 2)MONTH( @[User::varCurrentDate] ), 2 ) + "\" + (DT_WSTR, 4)YEAR( @[User::varCurrentDate] ) + RIGHT( "0" + (DT_WSTR, 2)MONTH( @[User::varCurrentDate] ), 2 ) + ".VER"

@[User::varCurrentDate] is a DateTime variable and is assign to 0 at design time

So the expression is evaluated as: "DB189912189912.VER".

My package contains 2 data flow.

At runtime,

The first one is responsible to set a valid date in @[User::varCurrentDate] variable. (the date is 2007-01-15)

The second one contains my custom data flow component with my custom property that was set to an expression at design time

When my component get executed, my custom property value is still "DB189912189912.VER" and I expected "DB200701200701.VER"

Any idea ?

Cannot Load Data Flow Tasks

Aug 3, 2007

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:

TITLE: Microsoft Visual Studio

Failed to create the task.


The designer could not be initialized. Microsoft.DataTransformationServices.Design)

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.

Re : Enabling / Disabling Data Flow Tasks

Apr 17, 2006


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.

Thank you

Maximum Data Flow Tasks Execution

Sep 10, 2006

Hi guys,

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.

please help???

Asynchronous Data Flow Tasks How To Run More Than 4 At A Time

Sep 25, 2006

Hi guys,

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.

any thoughts?

Opening A Data Flow Tasks Forces A VSS Check Out

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.

Creating A Parameter File For The Data Flow Tasks ??? VerY Urgent

Jan 2, 2008


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.???

Retrieve Value Within A Data Flow

Aug 29, 2006


I am doing a data flow to insert data into a dimension table(A) and master surrogate key table(B). Master surrogate key table(B) will be inserted prior to dimension table(A). My dimension table(A)'s key is depend on the last key in master surrogate key table(B). The data flow started from a flat file and checking if the key found in dimension table. If not found, insert a record into B. Then generate the new record to A with max id from B.

My question is how to retrieve the max id in master surrogate key table(B) in a data flow and use it as an input to my dimension table?

Transaction Inside A Data Flow Task

Oct 30, 2006

We are designing an ETL solution for a BI project using SSIS.

We need to load a dimension table from a source DB into the DW; inside the DW there are two tables for each source dimension table: a current dimension table and a storical dimension table.

The source table includes technical columns that indicate if each record was processed correctly by ETL procedures.

Each row in the source table can be a new record, or an exisisting one. If it's a new record, a corresponding new record should be inserted into the current dimension table of the DW; if it's an exisisting one, a new record should be inserted in the storical dimension table and the existing record in the current dimension table should be updated.

Furthermore for each record we need to update the source table with an error code. If the record was processed with succes the code is zero, otherwise it contains an error code.

I try to use a single data flow task, using the 'ole db command trasformation' task for managing update and 'ole db destination' task for managing insert.

The problem is that some insert and update should be executed inside a single transaction, for each record; for example if the source contains a new record I should insert the record in the current dimension table and update the source record with error code zero if every think goes fine.

There is some way to group task in the data flow pane in a single transaction ?

There is a better way to do that ?

I'm trying to assign this value to a user variable, but I can't figure out how to do that.

i can hack something silly together - like write the value to the db, and then get it out, but I there has to be an easier way..

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.Description =
"Secure String key value to decrypt the file";
            EncryptionKey.Value =
            EncryptionKey.ExpressionType =
            EncryptionKey.EncryptionRequired =

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"
((Microsoft.DataTransformationsServices.Controls) "<v:shapetype coordsize="21600,21600" filled="f" id="_x0000_t75" o:preferrelative="t" o:spt="75"

Programmatically Iterating Tasks/components In The Data Flow Portion Of A Package.

Mar 6, 2007

HI All,

In several threads there has been discussion regarding adding connection managers to a package's data flow, etc. My challenge is that I have a large solution that contains many packages, and I need to change the connection manager linked to the data flow in all of the packages. When the solution was initially designed, data sources were used, and it has become a tedious maintenance issue to keep those in sync. We want to use a standard OLEDB connection manager, but adding a connection manager to each package and editing the corresponding data flow tasks in each package to use that new connection manager is a daunting task. I've coded a .Net module to access the packages, remove the old connection manager (data source) and add the new OLEDB data source. However, as I traverse the objects in the package hierarchy, when I come to the data flow object, the innerobject is not a dts object, but rather a _com object.. I can't seem to find any documentation/examples as to how to iterate the tasks within a data flow and change the connection manager. If you have any information, that would be quite helpful. If you reply with a code sample, if you would be so kind as to relate it to one of the sample packages provided with SSIS so I can run it, that would be great.

Thank you.

I have yet another question. How can i pass data b/w 2 data flow tasks? I'm trying to get some data from one sql server and then I want to pass this whole bunch of data to another data flow task which is going to get some data from second sql server. I would probably combine them using union all and then save that as a transaction in a third sql server?

Information regarding how to pass the data with some detailed discussion would be fine with me.

How Do I Add An ODBC Connection Data Source As A Data Flow Source

Mar 2, 2007

I have set up a new connection as a connection from data source, but I cannot see how to use this connection to create my Data Flow Source. I have tried using an OLE DB connection, but this is painfully slow! The process of loading 10,000 rows takes 14 - 15 minutes. The same process in Access using SQL on a linked table via DSN takes 45 seconds.

Have I missed something in my set up of the OLE DB source / connection? Will a DSN source be faster?

Error: The External Metadata Column Collection Is Out Of Synchronization With The Data Source Columns

Apr 17, 2007


I have a SSIS package with a Data Flow task. This task transfers the data from SQL Server 2000 to a table in SQL Server 2005.

I deployed and tested this package on the Test Server. Then put this package in a job and executed it - Works fine.

On the production server- If I execute the package through DTEXECUI, it works fine. But when I try executing it through a job- the job fails and it gives me following error:

Description: The external metadata column collection is out of synchronization with the data source columns. The "external metadata column "T_FieldName" (82)" needs to be removed from the external metadata column collection....

What I don't understand is, why are there no errors displayed when I execute the package through DTEXECUI.

Can anyone help me to resolve this issue.

Search For Data Inside A Recordset Destination

Feb 21, 2007

Hi there,
I need to develop a module and wondering what would be the best implementation...

I get a list of files from a text file and store it in a Recordset Destination (object variable "CUST_INV_LIST").

I need to check that all the files in a directory are in the list. I can loop through the files in the directory using a ForEach container, but how do I check if it is in the CUST_INV_LIST recordset?

I thought about using another ForEach container to loop through the recordset, check if the physical file is equal to that row, if so set a flag, ... but it's neither elegant nor effective.

Another option would be to use a Script Task to search for the physical file name in the recordset. I tried with the Data.OleDb.OleDbDataAdapter, etc. but I get and error when I declare Data.DataTable. Anyways that method of accessing a recordset is not recommanded and seems complicated.

Any suggestion?

Data Flow Inside For Each Loop - Error Handling

Jun 23, 2006

Hopefully this is an easy question:

Inside of a for each loop (looping through an ADO record set of objects to import) I have a data flow task (along with many other processes).... if the dataflow task suceeds I log success in a table. If it errors I want it to fail the dataflow task (which will fire off my Event Handler for that data flow and log the failure, email etc) BUT I want it to continue the loop - I can't seem to figure out how to get the data flow object not to fail the whole loop. If any other objects inside the foreach, other than the data flow, fail I would like the whole loop to fail. Also if possible (but not a requirement) I would like it to have a threshold where if the data flow fails X variable times it will fail the package.

I am having difficulty how to not fail the loop when the import data fails..... just looking for a simple "on error next" type logic for that specific object in the foreach but not the rest. Thanks in advance for the help/advice.

I used slowly changing dimension to detect the changes for the records inside my Dimension table. But I had a problem when a new record exists in the stage table. The accountkey is set as the primary key and it gets its value from a different table which stores the last account key that was created. I cannot load all the changes unless i have a business key. Is there a way that i can get the "last key" from a different table in the data flow area and then supply it together with the other fields in the new output branch of the slowly changing dimension?
