Call FireQueryCancel() In A Script Component Within Data Flow Task?
Dec 18, 2007
I am trying to cleanly shutdown a dataflow task, which contains a script component, when RunningPackage.Stop() is called from the SSIS runtime.
I've been going in ever decreasing circles with no success - it looks like the cleanest way to find out whether RunningPackage.Stop() has been called is to call FireQueryCancel(). But I can't find any reference to anything useful in a dataflow task script component that gives me something that implements IDTSComponentEvents. The nearest thing seems to be Me.ComponentMetaData which gives a reference to IDTSComponentMetaData90, but this only has methods for calling FireError, FireInformation, FireProgress, FireWarning, and FireCustomEvent. But no FireQueryCancel.
Is there a way in a script component that I can find out the state of QueryCancel?
Any help would be apprecieated.

Dear Colleagues,
I'm trying to develop a custom Data Flow Transformization component in SSIS.
I compiled it without errors, installed it in the GAC and in the Pipeline Components-folder however I always get the following message when I'm trying to drag the component onto the designer surface:
The component could not be added to the Data Flow task.
Please verify that this component is properly installed.
------------------------------
ADDITIONAL INFORMATION:
The data flow object "RisikoKennzahlenKomponenten.MarktwertTransformation,
RisikoKennzahlenKomponenten, Version=1.0.0.0, Culture=neutral,
PublicKeyToken=cfa8722b8086ac2d" is not installed correctly on this computer.
(Microsoft.DataTransformationServices.Design)
Program Location:
at
Microsoft.DataTransformationServices.Design.DtsBasePackageDesigner.GetPipelineInfo(String creationName, IServiceProvider serviceProvider)
at
Microsoft.DataTransformationServices.Design.DesignUtils.GetNewPipelineComponentObjectName(IDTSComponentMetaDataCollection90
parentCollection, String clsid, IDTSComponentMetaData90 componentMetadata,
PipelineComponentInfo& pipelineComponentInfo)
at
Microsoft.DataTransformationServices.Design.PipelineTaskDesigner.AddNewComponent(String clsid, Boolean throwOnError)
This happens with EVERY custom component on my computer. The same components work fine on other machines.
Does anyone have an idea?
Regards
Arne Janning

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.

Dear all,
I am developing tools for automatic creation of data warehouse tables, cubes and SSIS packages. Generating the SSIS Data Flows works very well using the SSIS components for OLE DB Source, Derived Column, Lookup and OLE DB Destination.
However for some of the advanced functionality I need to use Script Component. I have managed to add it in the Data Flow with all inputs and outputs, but how do I populate it with my code? I've seen there is a component property called "SourceCode" and one called "BinaryCode". The "SourceCode" contains the code, but also some extra metadata.
Questions:
Do you know if there is any programmatic support to generate the Source Code property with the metadata necessary?
Do you know how to compile the Source Code and generate the property BinaryCode?
Example from my code below:
// Create script component
IDTSComponentMetaData90 script = dataFlowTask.ComponentMetaDataCollection.New();
script.ComponentClassID = app.PipelineComponentInfos["Script Component"].CreationName;
CManagedComponentWrapper scriptWrapper = script.Instantiate();
script.InputCollection.New();
script.OutputCollection.New();
scriptWrapper.ProvideComponentProperties();
script.Name = "Logics";
// Create path
IDTSPath90 scriptPath = dataFlowTask.PathCollection.New();
scriptPath.AttachPathAndPropagateNotifications(lastComponent.OutputCollection[0], script.InputCollection[0]);
// Populate input and output columns
IDTSInput90 scriptInput = script.InputCollection[0];
IDTSVirtualInput90 scriptVInput = scriptInput.GetVirtualInput();
foreach (IDTSOutputColumn90 col in oledbSrc.OutputCollection[0].OutputColumnCollection)
{
scriptWrapper.SetUsageType(scriptInput.ID, scriptVInput, col.LineageID, DTSUsageType.UT_READONLY);
IDTSOutputColumn90 tmp = script.OutputCollection[0].OutputColumnCollection.New();
tmp.Name = col.Name;
tmp.SetDataTypeProperties(col.DataType, col.Length, col.Precision, col.Scale, col.CodePage);
}
// Make script asynchronous
script.OutputCollection[0].SynchronousInputID = 0;
Thanks for any assistance and Best Regards,

Hello Helpers,
I need to know how to use my private function - created as a scalar-valued-function in SQL Server 2005 - in script component (here a transformation is used) in a data flow task to transform a two-digit-month into a tree-sign-month:
Example: '01' should be transformed into 'Jan'
Many thanks for alle your commitment and help!

Hi,
I'm trying to implement an incremental data pull (Oracle to SQL) based on Andy's blog:
http://sqlblog.com/blogs/andy_leonard/archive/2007/07/09/ssis-design-pattern-incremental-loads.aspx
My development machine is decent: 1.86 GHz, Intel core 2 CPU, 3 GB of RAM.
However it seems the data flow task gets hung whenever I test the package against the ~6 million row source, as can be seen from these screenshots. I have no memory limitations on the lookup transformation. After the rows have been cached nothing happens. Memory for the dtsdebug process hovers around 1.8 GB and it uses 1-6 percent of CPU resources continuously. I am not using fast load to insert new records into my sql target table. (I am right clicking Sequence Container 3 and executing this container NOT the entire package in the screenshots)

http://i248.photobucket.com/albums/gg168/boston_sql92/5.jpg
http://i248.photobucket.com/albums/gg168/boston_sql92/6.jpg
The same package works fine against a similar test table with 150k rows.
http://i248.photobucket.com/albums/gg168/boston_sql92/7.jpg
http://i248.photobucket.com/albums/gg168/boston_sql92/8.jpg
The weird thing is it only takes 24 minutes for a full refresh of the entire source table from Oracle to the SQL target table.
Any hints,advice would be appreciated.

I have a int value that I pulled from a table in a database and it is stored in a variable. I would like to increment this value in a script component and then insert it into a field in my ole db destination. Is there any example out there of using a script component to do something similar to this.
Do I want to select source, destination or transformation?
Can I/how do I access my variable from within the script component.
Any asistance or examples you can point me towards would be greatly appreciated.

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?

Hi,
I am trying to create a simple BI Application for SSIS. In Visual Studio 2005 I just get a Data Flow Task from the toolbar and add it to the project. When I double click it I get the following error:
The task with the name "Data Flow Task" and the creation name "DTS.Pipeline.1" is not registered for use on this computer.
Then when I try to delete it it gives this other error:
Cannot remove the specified item because it was not found in the specified Collection.
I am creating this application in an administrator account in this computer, so I doubt the problem is related to permissions. I am running SQL Server 2005 and Visual Studio 2005 in WinXP Tablet PC Edition.
Any suggestions why this is happening and how to fix it?

I am using SQL 2005 SSIS. I am joining several large tables and then the move result into another table in the same database.
I would like know which method is faster:
Use Execute SQL Task to insert the result set to the target table
Use the Data Flow Task to insert the result set to the target table. (Use OLE DB source to execute SQL command and then use the SQL destination)
Could you tell me why then other is slower?
Thanks.

Is there a default destination component used when a new data flow is created? The reason I ask is simply curiosity. I have an xml file with 2 pieces of data: item A and item B. A should simply get copied out of the file. B should undergo a quick transform. I set up an XML source such that two columns are mapped correctly to the XML source data of A and B. I set up my data transform task as well. So, if I leave those two components on the .dtsx page with no other components, then will there be a default data flow destination already created? ...OR, do you always have to have a destination component?
Thanks for the input. I am just curious.

I have a package variable that I set via an ExecuteSQL task. I want to reference it in a data flow script component. In the Script component I enter the variable into the ReadOnlyVariables collection, then in the script I reference it as Me.Variables.var. (E.G. counter = Me.Variables.var)
I'm getting errors when the data flow starts:
Error: 0xC0047062 at Provider, Set Surrogate Key [4261]: System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> Microsoft.SqlServer.Dts.Pipeline.ReadWriteVariablesNotAvailableException: The collection of variables locked for read and write access is not available outside of PostExecute.
I have no problem referencing other variables that I have in DerivedColumn transformations. I've tried putting the variable in the ReadWriteVariables collection but I get the same error. I don't understand why this is so difficult. Please help.

Hi,
I've read the various posts and articles regarding this matter, but I seem to have problems getting to work:
In my control flow, I start by declaring a variable named "LastJobLedgerEntryID", to identify the records I need to add to the stage. From there I would like to use this variable in the source component in my dataflow, i.e.:
"SELECT [Entry No_],[Job No_],[Posting Date],[Document No_],[Type],[No_],[Description],[Quantity],[Direct Unit Cost],[Unit Cost],[Unit Price],[Chargeable],[Job Posting Group],[Global Dimension 1 Code],[Global Dimension 2 Code],[Work Type Code] FROM mytable WHERE [Entry No_] > " + @[User::LastJobLedgerEntryID]
But this fails? I should note that the variable LastJobLedgerEntryID is stored as a int32, and with the default value of 0
Could someone please help me with this?
Thanks in advance!

I'm wondering if it is possible to create a flat file source on the fly while bypassing the following step:
On the Connection Managers page, add or create the Flat File connection manager, using a descriptive name such as MyFlatFileSrcConnectionManager. Then close the Script Transformation Editor.
I want to create the connection totally in script, yet i'm having a hard time proving this out...does anybody have any
experience with this?

Hello-
I have an SSIS package which I've been using for nearly a year now. Basically the package is responsible for looping through a directory, and importing pipe delimited files into a database.
The issue I'm having is with the UnDoubleError data flow component. I've been using it to remove the qualifiers from the data being imported, in this case it happens to be double-quotes. ex: { " " } I have found that the component will insert a single double-quote { " } when it finds a null string, or two consecutive qualifiers for that matter. If there are two qualifiers with a space seperating them, then it will insert an empty string, or rather a string with one space in it, and the qualifiers will be removed.
The dilemma is since the log files have some columns which are technically NULL, by that I mean columns where there exists only two qualifiers ex: { "" } the UnDoubleError component then inserts a single double-quote. I want to retain the NULL value if it exists, though still use the component to remove the qualifiers when there actually is data there.
Any suggestions?
Thanks for the help...

I'm trying to get a record count out of a databse using OLE DB Source and row count tasks but keep getting an error. I set up a variable as int32 and select the variable name in the row count task and when I go to the Input Columns tab to select a field to count, it gives me this error:
Error at Data Flow Task[Row Count[505]]: The component "Row Count" (505) has forbidden the requested use of the input column with lineage ID 32.

Hi
After having read the forums I understand that it is not possible to use parameters in the "Ole Db Command", when connecting to Oracle.
What I have to do, is to delete a record in an Oracle table from within the "Data Flow", based on parameters.
It does not seem to be possible to create the SQL statement in a variable (with parameters generated) and use the variable in the "Ole Db Command"
Instead I probably need to use the "Script Component"?
So what I need is step by step guidance for how to connect to and interact with an Oracle database from a Script Component, what to import and where, what to declare and where, and generally a way to get this to work.
Any help appreciated.

Does anyone know how to hook up to data flow pipeline events via custom solution (C#)? I am trying to write code to log start and end times of components(lookup,merge joins etc) in a data flow task. I tried with a class inheriting from the EventsProvider class but it didn't work as this is only for container tasks. Any ideas will be greatly appreciated.

oledbItemMasterSource.ComponentClassID = "DTSAdapter.OLEDBSource";
oledbItemMasterSource.Name = "InventTable";
oledbItemMasterSource.Description = "Get Item Master";
After creating this package i found that 'InventTable" is not set to OLE Db Source component. where as i can set name to OLE DB Flat File destination component.

I want to insert data calling a stored procedure and call this from a Data Flow destination object. Is it possible?
I understand that Ole Db Command transformation object can call stored procedure, but that will not rollback in the event of error in the middle.
I understand that Ole Db Destination object will rollback in middle of import, but I don't see how to do the insert by calling stored procedure. "Sql Command" option in Ole Db Destination object does not seem to present solution to the problem.
Am I missing something here or is Ssis / Microsoft demanding that Insert stored procedure not be used when using Data Flow destination object to insert data into target table?

Hi,
I have SSIS which will have OLF DB Source, and then have Derived Column component to managering all data from OLF DB Source. I used to have default columns such as Create Date, Update Date set as fixed date. Now we decided to put this default column values into a table to manage. I then have problem to choose which component I should use in order to have this columns selected from default table.
For example: if Create Date is null, I have to select default value from the default table; otherwise, use Create Date value and so on.
Thanks,

I have found not very good behavior of Union All Data Flow Component.
I have Script component and about 30 Union All Data Flow Components. I have string field named 'MyField'. Legth of the field is 15 characters. The field appears first in Script component (defined as 'MyField' Output collumn) and present in all Union All Data Flow Components. I need to change field length from 15 to 10. In Script Transformator Editor of Script component I changed 'MyField' Output collumn Length property value set it to 10. But length of the field remains 20 in all Union All Data Flow Component downstream and no errors no warnings appears. To fix this i recreated (deleted and added again) 'MyField' in all Union All 30 Data Flow Components.
If extend length from, say, 15 to 20 in the first of Union All Data Flow Components error sign appears
"Error 1 Validation error. Data Flow Task: Union All [22]: The metadata for "input column "MyField" (144)" does not match the metadata for the associated output column."
and only recreation of the field in all Union All Data Flow Components can help to fix it.
May be someone knows other solution to fix such behavior?

Hi,
I'm pretty new in SSIS and i have some problems with error log. I want to get detailled error description in a script component of a dataflow. for the moment I use thooses lines
Row.ErrorDesc = ComponentMetaData.GetErrorDescription(Row.ErrorCode)
and for unique constraints on a sql table I have this error : The data value violates integrity constraints.
For the same error, if i use an event handler on error, i have more row and the first of them is more explicit (Variable System::ErrorDescription)
An OLE DB error has occurred. Error code: 0x80040E2F.
An OLE DB record is available. Source: "Microsoft SQL Native Client" Hresult: 0x80040E2F Description: "The statement has been terminated.".
An OLE DB record is available. Source: "Microsoft SQL Native Client" Hresult: 0x80040E2F Description: "Cannot insert duplicate key row in object 'dbo.dimDepot' with unique index 'IX_dimDepot'.".
Is that possible to have a so detailled error text in a script componnent of a data flow? If yes, How?
Or if i use error event how can authorize the dataflow go ahead even if there is error.
thanks for you help

Hi,
I'm having my first go at developing a destination adapter which will send data to an update Web Service.
I've got some rather big gaps in my understanding. I've been following the various samples I've found on the net and have validated my mapping and picked up all the available column names and datatypes which are appearing in the Input and Output Properties tab of the Advanced Editor but I only have a tab for "Input Columns" and not "Column Mappings".
Which method defines the availble columns for the user to map?
Let me know if I haven't given enough information.

Hi,
I created a package with SQL 2005. The package gets the Access DB and then inserts it into SQL Server.
If I open the package in .NET, I can see the SQL Task and Data Flow Task. The SQL Task has a property sqlstatementsource, which has the necxessary SQL code to create the tables.
How can I tell the SQL Task to recompile the SQL code if I give it another DB name, because the tables differ and don't map in the Data Flow Task
Thanks
