Hi,
I have a SSIS Package which I would like to modify using SSIS API. I need to put new component between some two existing data flow's components. During this process I need to disconnect two data flow's components using SSIS API. How can I do that?
Thanks,
Rafal
Everything I've read says that custom data flow components are built by inheriting from the Microsoft.SqlServer.Dts.Pipeline.PipelineComponent class.
But the stock components such as the Derived Column data flow transformation must each be implemented by their own class. So how do I base my custom components on those classes? The documentation for the PipelineComponent class doesn't list any such subclasses.
I created a SSIS package and several data flow componenets for this package.
What does strategy exist to deploy SSIS package and data flow components into a enterparise server?
Thanks in advance.
We're experiencing a problem where intermittently our SSIS packages will hang. There are no log errors or events in the event viewer. It will happen whether the package is executed from the SQL Job Agent or run from BIDs. When running from BIDs it appears to hang inside one of the data flows (several parallel pipes with sorts, merge joins etc...). It appears to hang in multiple pipes within the data flow component. The problem is reproducable, we just kill it and re-run, and it appears to hang in the same places.
Now here's the odd thing: as we simply open and close some of the components in the pipe line after the place it hangs, a subsequent run will go further in the pipeline before hanging. If we open and close all the components after the point it initially hung, the data flow will run fine, from there on out. When I say "open and close" I mean no changes are made, we simply double-click the component, like a merge join, then click 'close.'
To me this does not seem like a memory problem but likely something is wrong with the metadata, where opening a component and closing it somehow alters the metadata to "right it".
This seems to occur intermittently after we make modifications to the package. It's like if you make any mod, even unrelated to the data flow, you then have to go through and open and close every component in your package to ensure it will work. Again, no errors or warnings are fired.
Has anyone seen this type of problem?
Hello,
Is it possible to use existing data flow components (Merge Join, aggregation,...) in a custom data flow component?
Thanks,
Yoann
Does anyone know a good place to download (or even purchase) custom data flow components?
Some ideas I've had (and I'm sure I'm not the first):
Transformations:
Filter
Sometimes I just want to filter out certain rows.
Unicode Converter
Convert all unicode columns in place.
Sequence Column
Adds a column with a sequence of numbers. Or perhaps even random numbers.
GUID Column
Adds a column with a GUID.
Destinations:
Garbage
Would act as a visual indicator in the designer that these rows are being discarded. You could add a data viewer right before it too.
Log File
Good for redirected error rows, writes them to various log files.
Email
Along the same lines as Log File, but sends off all the rows in a single email. Great for day to day things. Nothing too critical.
Hello everyone,
I am developing an SSIS solution where the Data Flow task extracts data from a source csv file, then performs several transformations on the source data and then starts inserting the cleansed data into several destination tables.
The Data Flow task is getting too large!
Question:
Is there a way (best practice) for grouping components in the Data Flow - similar to the Container concept in the Control Flow?
I know this question sounds too luxurious, but I really loose the overall picture, when the Data Flow canvas gets too crowded.
Thank you in advance.

I've been having an issue with the integration of a third-party DLL into a custom data flow component.
The company sent me a C# project that generates a simple console application. The project includes a class that calls their DLL with DllImport. The console application runs fine.
I created a stand-alone class using the C# class they sent to expose the methods of their DLL. In my custom component, I'm referencing this class to pass data to and from their DLL.
The first method from that stand-alone class that my component encounters simply gets their installation path from the registry and does not use DllImport. That path retrieval works fine. The next method calls a function that is declared with DllImport. Each time the call fails with "System.DllNotFoundException = {"Unable to load DLL AMZip.dll': Exception from HRESULT: 0xE06D7363"}".
I've copied this DLL to countless locations (e.g., the PipelineComponents directory, the project/solution bin directory) and included these paths in all manner of path variables.
What am I missing here? Their DLL is not strong named (does this matter since I'm using DllImport?), my stand-alone class is, and of course, the custom component itself is. I appreciate the help.
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.
Steve.
I have Data Flow task that contains 50 components.
My computer configuration: 1 GB RAM Microsoft Windows Server 2003
Periodicaly when i try to save package after making some changes Out of memory ... exceptions message box appears , and soon after this Not fatal error occurs ... message box shows . If i close solution and open it again all my 50 components disappears --instead I see clear list, and all my work losen.
Such "Not fatal errors" making hell out of job -- every time I need to change package i must add package to archive!!!
Hi everyone,
Primary platform is 64 bit cluster.
How to move information allocated in SSIS variables from Data Flow to Control Flow layers??
We've got a SSIS package which load a value into a variable inside a Data Flow. Going back to Control Flow how could we retrive that value again????
Thanks in advance and regards,
The following is a list of questions that I have not been able to obtain concrete answers. I am probably missing something:
1) ReadWriteVariables -- can the updated value for a ReadWriteVariable be accessed within the same data flow? It appears not as I think the PostExecute() fires at the completion of the data flow not the end of the Script Component. Secondarily, the Script Component is a non-blocking transformation so the component does not "see" the end of the pipeline prior to sending data down stream.
2) Record Count -- Because of #1 above, How could you calculate a record count for a data stream? It does not appear that one can calculate the number of records for a data stream within a data flow and then access the count from within the same data flow.
3) FinishOutputs() -- Is the concept of FinishOutputs() applicable to Script Component Destinations? Asked another way, is FinishOutputs() executed at the end of the data stream regardless of whether there are "real" outputs for the component? I can create a "Dummy" output to create FinishOutputs() but is this ok?
4) Script Component -- It appears that the Script Component Source, Transformation or Destination are really defined based on the columns defined in "Inputs and Outputs". Can you convert an Source script component to a transformation script component by simply adding an Output?
Sorry for these basic questions but I am not getting it completely. As you can tell...
I am building a package that will be used to transfer data from Access 2000 to SQL 2005. For development purposes, the first thing I do is search for my SQL database. If it is there, I drop and recreate it. If I run the package once, it runs fine, . After that, I get the message that the database is in use and can not be deleted. I do not have Mgmt Studio open, so the only thing that could have a connection is the BI Studio. The only way I can seem to clear it, is to close and reopen BI Studio and the package. To make matters worse, it does not happen all the time. So sometimes I can run the package as many times as I would like, until it chokes, and then I get to start all over again. Has anyone else seen something like this, or am I missing something in the package and/or task settings? Please let me know.
Thanks,
DO
I need to see inside a SSIS 2012 project a new SSIS installed component, but in the SSDT 2010 I cannot see the SSIS Data Flow Items tab for adding data source/data destination respect to the choose toolbox items pane.

I need to call a stored procedure to insert data into a table in SQL Server from SSIS data flow task.
I am currently trying to use OLe Db Destination, but I am not sure how to map inputs to OLE DB Destination to my stored procedure insert.
Thanks
There is a table with a column that contains Xml documents. For each record from my Data Flow Source, I want to pass in the Xml document and the node to interrogate, and return the value contained in the node. Like the Crm component, this is probably one I will have to write from scratch in C#, but I would like to avoid having to create the custom component if it already exists in the public arena.
Does anyone know of any Xml Ssis Data Flow Components that are downloadable for free?
I was working all day making changes to my 3MB package. I was adding a large number of transforms that were copied-and-pasted from elsewhere in the same data flow task.
All was going well. I even took the time to have SSIS lay out the task again (1/2 hour). Suddenly I started receiving some strange errors:
After the layout, I noticed two stray components 'way off in the upper right corner. I found that one of them had a duplicate name to a component which had been added hours ago. Even after deleting it, I got "duplicate name" errors.
I copied three components in one selection, and when I tried to paste them, got the error "can't initialize component on paste". I tried them one at a time, but got the same error.
I got errors about COM failures due to marshalling to another thread
I then exited Visual Studio and started it again. To my great surprise, the data flow task I was working on was still there, but was completely empty.
Comparing what I'm left with to my last version in source control, I find that the entire pipeline element is missing from the DTS: ObjectData element!
I'm developing a real love/hate relationship with SSIS. It varies from one day to the next. Guess what kind of day this is!
Hi,
I am using SSIS in SQL Server 2005 and want to have a query like this in my data flow task
Select a.*
from abc as a
inner join (Select max(b.id) as ID from xyz as b inner join pqr as c on b.id = c.id and b.id > ?) as t1
on t1.id = a.id
SSIS fails to detect the parameter (?) for the inner query and gives message.
"
Parameters cannot be extracted from the SQL command. The provider might not help to parse parameter information from the command. In that case, use the "SQL command from variable" access mode, in which the entire SQL command is stored in a variable.", so assuming this is your problem, then you can workaround.
"
The idea is to parameterize the inner query ,,,
(so if the above query doesnt make sense ignore it )
Hi, there,
I am having some problems with the loading of tab delimited text file (source) to a SQL Server table (destination) using the SSIS data flow task. Package has been executed successfully with no error msg. The number of rows in the text file also matches the number of rows in the SQL table. But, when I check the content of the table, I noticed some of the columns contain NULL which supposed to have value. This happens not to all the rows but only to some rows. I did some testing by removing some rows from the beginning, middle and end of the text file and re-run the package but the result is quite inconsistent. Sometimes, the field got filled, but sometimes, it just contains NULL where it supposed to have value.
What will be the possible causes to this?
Thanks in advance.

Yong Hwee
Hi,
I am experiencing an error where the ssis data flow task would freeze and stop data export from a oledb source to a text file. It doesn't generate any errors the ssis package would just hang. This only happens when I run it in 64 bit mode. When I change the mode to 32 bit the ssis never freezes and runs fine. Has anyone experience this? Is there a fix so I can run my jobs in 64 bit mode?
Thanks,
Hi ,
Is there any option to use OLE DB Source in Script Component?
Thanks

Hi!
When I add a Data Flow Task to a package, save it and then close. When I open it again, I get 3 errors and the detail of the Data Flow Task is empty.
I had try to uninstall and install my SQL Server 2005, but the problem continues.
Can some one help me on this?

I am loading a lot of Excel and CSV files to SQL Server. Some loading may fail for various reasons. I want a file either be load as a whole or nothing. Currently I keep a list of failed filename and remove it at the end (I add a column for source file name).
Any better way to make sure a file is loaded as a whole or nothing?
Thanks,
I would like to know how I can add the following sample code to my Source data on Data Flow on SSIS, or what other options there are. The main issue is time as we have talking about 100's of millions of rows
select Sample,
CASE
WHEN Sample IS NULL
THEN NULL
WHEN SUBSTRING(Sample, 1, 6) IS NULL
THEN ' '
ELSE RTRIM(SUBSTRING(Sample, 1, 6))
END AS [Sample_1_6]
from TestTable
what I have done at this stage is just to Create a SQL task with a Insert into
INSERT INTO [dbo].[TestTable1]
([Sample]
,[Sample_1_6])
select Sample,
CASE WHEN Sample IS NULL =THEN NULL
WHEN SUBSTRING(Sample, 1, 6) IS NULL THEN ' '
ELSE RTRIM(SUBSTRING(Sample, 1, 6))
END AS [Sample_1_6]
from TestTable
If there is a way adding this to a dataflow so I van use fast load that would really be the best solution. I know there are derived columns, but would this really be faster than the straight insert into in a SQL Task? If this is the way to go what is the code I would use in the derived column or any other option.
I have a relatively simple SSIS package that I'm building for a data mining process. The package starts with an OLE DB data source, passes the results of a SQL Command (query) along to a conversion step, which then gets sent to a Term Lookup task. The Term Lookup then writes the result to an OLE DB Data Destination. Pretty simple. The OLE DB data source query returns about 80,000 rows if you run it through SQL WB. The SSIS editor shows 9,557 rows make it out of the source, and into the conversion step, 9,557 make it out of the conversion and into the lookup, and about 60,000 rows make it out of the lookup and are written to the results table. Then the package fails with the following errors listed on the progress screen. I was assuming that the 9,557 was some type of batching that was occurring in the process, but now I'm not so sure.
Thoughts?

Does anyone have a helpful link for using the partition processing data
flow task in SSIS? I am trying to process a monthly partition
from within my package and am getting the following error:
Error: 0xC113000A Errors in the high-level relational engine. Pipeline
processing can only reference a single table in the data source view.
If anyone has used this before and could point me in the right direction, I would appreciate it.
Thanks,

I have a package that loads staging tables from an Oracle source DB. In the data flow tab I have 30+ read table/write table task combinations. When I run the package 3-4 of the read/write combos execute at a time. What I'm trying to control is the priority order of the combo execution. My goal is to minimize to total load time by having the larger table transfers run first and the smaller table transfers fill in until they are all complete. Currently, the largest table (16 million) transfers last (because it was the last combo that I created?).
Thanks,
Dave
I am creating a staging database in which I am loading required tables from 2 different sources.
I have 30 different tables to load from source 1 and 10 different tables from source 2.
This is the way I am doing, in Control flow task I am using Sequence container and in that I included the data flow task, the data flow task
has source OLD DB connection from where I select the table and then destination OLE DB connection where I load the data.
So for 30 tables I have one Sequence container with 30 different data flow task and each data flow task has OLE DB source and OLD DB destination.
I wanted to find out if this is the efficient way to do, or if there is any other way to do this.
And for source 2 shall I put in another package or shall I use the same package with different sequence container and follow the same steps
as for Source 1 tables.
Please advice.
Thanks,
Has anyone come up/determined a generic way to capture and log indicative information within a data flow in SSIS - e.g., a number of rows selected from the source, transformed, rejected, loaded, various timestamps around these events, etc.? I am trying to avoid having to build a custom solution for each of the packages that I will have (of which there will be dozens). Ideally, I'd like to have some sort of a generic component (such as a custom transformation) that will hide the implementation details and provide a generic interface to the package.
It is not too difficult to achieve something similar on the control flow level, but once you get into data flows things get complicated.
Any ideas will be greatly appreciated.
Hi all...
I'm creating a SSIS in the designer view of SQL Server BI Dev. Studio (SQL Server 2005)
I need to import a whole table from MS Access into my local SQL Server.(this task will be performed weekly, so once working I'll schedule a job for it)
I've created a 'FILE' connection to MS Access in the 'Connection Managers'.
When I'm on the 'Data Flow' tab I can't find a Data Flow Item to use as a MS Access connection.
(available on the 'Data Flow Sources' are only: DataReader, Excel, Flat File, OLE DB, Raw File and XML Sources)
What am I doing wrong/missing?
Thanks for your help.
I have just installed Service Pack 2 on my SQL 2005 Standard Edition.
However, now all my SSIS packages will not allow me to open my Data FLow Tasks. I get the following error:
TITLE: Microsoft Visual Studio
------------------------------
Cannot show the editor for this task.
------------------------------
ADDITIONAL INFORMATION:
The task returned an unsupported control editor type. (Microsoft.DataTransformationServices.Design)
If I try to create a new Data Flow task I get:
TITLE: Microsoft Visual Studio
------------------------------
Failed to create the task.
------------------------------
ADDITIONAL INFORMATION:
The designer could not be initialized. (Microsoft.DataTransformationServices.Design)
I have tried to install the latest hotfixes after this but they had no effect.
Can anybody help me???? Please?
Hello.
I am using the "SSIS Log Provider for SQL Server" to log events to a table for "OnError" and "OnPostExecute" events of a package. This works as expected and provides a nice clean output on the execution steps of the package.
I am curious as to why I do not see any detail for any/all tasks that fall under the "Data Flow" section of the package though. For instance, on my "Control Flow" tab, I added a "Data Flow" task that simply loads a few tables from a target to destination server. However, there is nothing shown in the logging output. Just that a Data Flow task was initiated. And when I'm configuring this logging under "SSIS-->Logging" in the checkbox area on the left, you cannot "drill into" data flow steps.
Is there a reason why there is no detailed logging for Data Flow tasks? Would getting to that require me to create a custom log provider?
Thanks for the help.

What are the advantages and disadvantages of having multiple data flow tasks in one SSIS package?
Is this a good idea at all considering the workflow may be similar now but may change in the future? Should it be left as one data flow per package?
