dear experts,
i'm trying to build a package programmatically from client c# application. I'm working to create three dataflow components:
- OleDB Source
- Derived Column Transformations
- OleDb Destination.
My package works good, but i have several problems when insert an expression as Value of an IDTSCustomPropriety90 object, like this one:
[LEN](#firsname.lineageID) > 5 ? <<if true>> : <<if false>>
Simple expressions like concatenate strings, for example "#firstname.lineageID" + "#lastname.lineageID" seem to work good.
Hi all I'm into a project which uses a lot of views for joining 2 or more tables. Using the MERGE component in SSIS will be a huge effort coz it only has 2 inputs and I gotta SORT the input too. Isnt it possible to have a VIEW like component that joins more than 2 tables and DOESNT need sorting?? (I've thought about creating views in database engine but it breaks my data floe in SSIS and is'nt a practical solution)
I am loading/executing packages from c# and I need to populate a temp table from user input and pass this table as a variable to the datareader source components sql command. I am using expression to build this query, but I am getting design time error when I have this command..
"select id, (SysDate + 28) as ExpiresDate from Table1 where id in (Select Id from" +@[User::Table2]+")"..
I have declared Table2 as a variable of type Object and I am creating Table2 in C# and I am assigning that Table to the user Table. But in the design mode, I am getting an error...expression cannot be evaluated.
Is there a way of disabling a custom property in a component so that during design-time the property is grayed out? I looked around the properties of IDTSCustomProperty90 and nothing sticks out.
Near the end of 2005 Microsoft made available some sample C# apps that implemented custom SSIS tasks and components. I think Doug Ladenshlager may have had a heavy hand in building them.
Does anyone know where they are? I can't darned well find them!
Does anyone here have a favorite site or set of sites with resources on SSIS custom component (tasks, transforms, log providers, etc.) development? I've been searching around to try to find this on my own, but so far I've had little luck.
Darren - I've noticed that you always seem to have the most insightful responses to questions related to SSIS .NET development (such as your recent response to evaluating expressions in a custom component) so I am particularly interested in anything that you have to share.
I created a SSIS custom component, transformation (Asynchronous) with one Input collection and 2 output collections.
The SSIS Package which includes the Component I created works well in the Business Intelligence Studio, but when the same Package is run in the 'Execute Package utility' It fails to run. ( when you Double click on the dtsx file)
The cause of the failiure is
public override void PrimeOutput(int outputs, int[] outputIDs, PipelineBuffer[] buffers)
method receives only one output buffer when executed using the 'Execute Package Utility' { outputs = 1 , buffer.Length = 1 } ( when executed in the BI studio, the method receives parameters of both the output buffers that I expect { outputs = 2 , buffer.Length = 2 } )
The property ComponentMetaData.OutputCollection.Count = 2 as well. Yet the PrimeOutput method provides only 1 buffer.
The Validation Succeeds on both instances, which I assume means that Meta Data is Provided Properly.
What would be the reason for the same pakage to run in 2 different ways like this,
What might I have missed out to do, to make the package run in different ways on 'Business Intelligence Studio' and 'Execute Package Utility'
Thanks a lot
Below are some of the lines from the ProvideComonentProperties Method which deals with the output Collection, Isn't this sufficient for the PrimeOutput to provide 2 output buffers?
ProvideComponentProperties()
public override void ProvideComponentProperties() {
I have implemented a custom source component that can be used as the data source in the Data Flow task.
I have also created a custom UI for this component by using the IDtsComponentUI .
But my component does not have the capability of setting the custom properties via the DTS Variables using the Expression Builder.
I have looked around for samples on how to do this, but I can only find samples of how to do this for custom Control Tasks, i.e. IDtsTaskUI.
My question is, How can implement the Expression Builder in my custom Source component + custom Source UI. Or do you know of any samples which I can look at.
When I try to debug the break points will always say the source code is different from the current version, but the custom component in the GAC has the new version number. The other strange thing is the toolbox will not reset to the original version meaning it will not remove the custom components. The funny thing is after I compile the custom components and restart VS the custom component runs with the new code changes. I can see the new features I added, but the debugger and toolbox still seem to be broken.
I have tried the following 1) Reset the tool box. 2) uninstall all my custom dll from the GAC €œC:WINDOWSassembly€? 3) remove all my custom dll from €œC:Program FilesMicrosoft SQL Server90DTSPipelineComponents€? 4) restart VS 2005 5) reselect the custom components. 6) reboot my computer.
It seem like VS has another cache. For the tool box or something.
I am creating a customer data flow component for SSIS for use in a package. I've got some custom properties that I am exposing using the supplied advanced editor (no custom property editor here).
Some of my properties are enumerated types, and I have deciphered how to get those properties to show as dropdown lists of their respective enumerations. (For those of you who may be looking as hard as I did as to how to accomplish this, see the end of this post.)
I also have a few properties which request SSIS package variable names - such as an file name variable. However, I can't figure out how to tell the advanced editor that the property is looking for an SSIS variable, so that it can show a dropdown list of package variables, much like virtually any other Microsoft supplied Data Flow component can.
Is there a Type Converter I could specify for those custom properties? Is there another way to instruct SSIS that my custom property is expecting a variable? Or do I need to code a custom UI for editing my Data Flow Task?
To create a dropdown list of values for a custom property that represents an enum, do the following:
1. Create your enum definition, such as "public enum ThisIsMyEnum { one, two }"
2. Create a new class that inherits from TypeConverter, such as "public class MyEnumConverter : TypeConverter"
3. Override "CanConvertFrom", and return true if "sourceType == typeof(string)"
4. Override "CanConvertTo", and return true if "destinationType == typeof(string)"
5. Override "ConvertFrom", and return the enum value (such as "one" or "two" in my example) that corresponds to the string passed in the parameter "value"
6. Override "ConvertTo", and return a string that corresponds to the enum value passed in the parameter "value"
7. Override "GetStandardValuesSupported" and return true
8. Override "GetStandarValuesExclusive" and return true to indicate that ONLY the enum values should be accepted
9. Override "GetStandardValues", and return a new StandardValuesCollection constructed with Enum.GetValues() of your enum, such as "return new StandardValuesCollection(Enum.GetValues(typeof(ThisIsMyEnum)));"
10. Just above your "public enum" declaration, add a "TypeConverter" attribute to link your type converter to your enum, such as "[TypeConverter(typeof(MyEnumConverter))]"
11. In "ProvideComponentProperties", after you've created your custom property like this: "IDTSCustomProperty90 propEnum = ComponentMetaData.CustomPropertyCollection.New()", add another line to specify the TypeConverter property of the property to the full assembly name of your type converter, like so: "propEnum.TypeConverter = typeof(MyEnumConverter).AssemblyQualifiedName;"
Hi, I am using custom dll in script component in SSIS package. This dll is looking for some configuration settings and dsplays the message as "Configuration section could not be found in the configuration source" . Please tell me the configuration source it looks for.
I am writing a custom dataflow transformation component and I need to get the name of the preceeding component.
I have been trying to find a way to get a reference to the Package object, MainPipe object or IDTSPath90 object (connecting to the IDTSInput90 of my component) from my component because I think from there I can get to the information I want.
What I want to accomplish is that at design time the designer can enter a value for some custom property on my custom task and that this value is accessed at executing time.
I have created a package which simply imports data from a flat file to a SQL Server table. But I need to incorporate a data conversion component by which I may change the source-destination column mapping programmatically. So what I thought that I need to add a data conversion component into the dataflow task. After adding this component (I found its component id as {C3BF62C8-7C5C-4F85-83C3-E0B6F6BE267C}) I have created a path which establishes the mapping between output columns of source component and the input columns of data conversion component. Now I am not sure how to establish the mapping between the data conversion component€™s input column collection and output column collection.
I am giving my code snippet here, IDTSComponentMetaData90 sourceDataFlowComponent = dataFlowTask.ComponentMetaDataCollection.New(); sourceDataFlowComponent.ComponentClassID = "{90C7770B-DE7C-435E-880E-E718C92C0573}"; €¦ €¦ €¦. // Code for configuring the source data flow component
IDTSComponentMetaData90 conversionDataFlowComponent = dataFlowTask.ComponentMetaDataCollection.New();// creating data conversion conversionDataFlowComponent.ComponentClassID = "{C3BF62C8-7C5C-4F85-83C3-E0B6F6BE267C}";// This is the GUID for data conversion component CManagedComponentWrapper conversionInstance = conversionDataFlowComponent.Instantiate();//Instantiate conversionInstance.ProvideComponentProperties(); // Now creating a path to connet the source and conversion IDTSPath90 fPath = dataFlowTask.PathCollection.New(); fPath.AttachPathAndPropagateNotifications( sourceDataFlowComponent.OutputCollection[0], conversionDataFlowComponent.InputCollection[0]); // Sould I need to accuire connect for data conversion? Im not sure conversionInstance.AcquireConnections(null); conversionInstance.ReinitializeMetaData(); // Get the input collection IDTSInput90 input = conversionDataFlowComponent.InputCollection[0]; IDTSVirtualInput90 vInput = input.GetVirtualInput(); foreach (IDTSVirtualInputColumn90 vColumn in vInput.VirtualInputColumnCollection){ conversionInstance.SetUsageType( input.ID, vInput, vColumn.LineageID, DTSUsageType.UT_READONLY); }
.. . // Well here I am stucked. What I need to do here to establish a map // between conversionDataFlowComponent.InputCollection[0] and // conversionDataFlowComponent.OutputCollection[0]?
As you can see I am just away from creating the mapping between input and output collection. Can anybody give me an idea how can I achieve this?
I will appreciate all kind of suggestions and comments.
Does anyone have any examples of programmatically creating a Transformation Script Component (or Source/Destination) in the dataflow? I have been able to create other Transforms for the dataflow like Derived Column, Sort, etc. but for some reason the Script Component doesn't seem to work the same way.
I have done it as below trying many ways to get the componentClassId including the AssemblyQualifiedname & the GUID as well. No matter, what I do, when it hits the ProvideComponentProperties, it get Exception from HRESULT: 0xC0048021
Does anyone know how to create a Source Script Component programmatically. I can only seem to create a Transformation Script Component. I have this:
PipeLineWrapper.IDTSComponentMetaData90 sourceComponent = ((dataflowTask as TaskHost).InnerObject as PipeLineWrapper.MainPipe).ComponentMetaDataCollection.New();
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?
I am trying to call a SSIS package from a web service hosted on the same machine as the package file is sitting. The package is running fine from the Agent and also by the "Integration Services Project" in VS.NET.
I had a lot of problems with permissions but they are resolved, at least I have no error messages to point to that direction. Now I am getting these results:
1. Error: -1073659874 / Description: The file name "\Diver-svrInputDataFilesdn_cust.txt" specified in the connection was not valid.
I'm building packages programmatically and all is well. I have a new custom transform that I developed. It also works fine. Now I'm trying to add my new component to my packages when I programmatically build them, and I'm unable to do that.
Has anyone added their own custom components to a programmatically built package successfully?
I get a COM error on the line that calls ProvideComponentProperties. I've attempted various modifications including not overriding ProvideComponentProperties or just having it do nothing. I always get the same result. What I don't understand is that the custom transform works and handles ProvideComponentProperties fine when it is added to a package in BIDS.
In a Data Flow, I have the necessity to use a SSIS variable of type €œObject€? inside Script Component and assign to it the content of 'n' variables of string type. On exiting from the script the variable of type object should contain something like in the following lines: AAAAAAAAAAAAAAAAAAAAAAAAAAAAA BBBBBBBBBBBBBBBBBBBBBBBBBBBBB CCCCCCCCCCCCCCCCCCCCCCCCCCCCC DDDDDDDDDDDDDDDDDDDDDDDDDDDDD €¦€¦€¦€¦€¦€¦€¦. €¦€¦€¦€¦€¦€¦€¦. On exiting from the data flow I will use the variable of type Object in a Script Task, by reading each element in a cyclic fashion. Is there anyone who have experienced something like this? Could anyone provide any example of that? Thanks in advance!
I am writing a custom transformation component that utilises a user variable.
Before using the variable at run time I am checking that the variable exists, but it would be nice to be able to add it if it does not. I cannot find any documentation on the subject, though I can see that the Variables class is derived from a ReadOnlyCollectionBase.
Is there a way to add a user variable with package scope from a custom component, either at run time or design time?
I've run into this a second time now. I'm hoping for some resolution AND guidance for proper build, save, etc. protocols in BIDS.
I've coded a custom component, included post-build procedures to add it to the GAC, selected it from the "Choose Items..." menu, and successfully added to a data flow. I've then been able to succesfully debug it.
This was all Friday afternoon. I shut down my BIDS session(s) and called it a week. This morning when I open BIDS, I get the following error when I attempt to add it to a data flow task:
TITLE: Microsoft Visual Studio------------------------------The component could not be added to the Data Flow task.Could not initialize the component. There is a potential problem in the ProvideComponentProperties method.------------------------------ADDITIONAL INFORMATION:Error at Data Flow Task [DTS.Pipeline]: Component "component "" (16)" could not be created and returned error code 0x80131600. Make sure that the component is registered correctly.------------------------------Exception from HRESULT: 0xC0048021 (Microsoft.SqlServer.DTSPipelineWrap)------------------------------BUTTONS:OK------------------------------
What would explain this? I'm new to VS/BIDS. Am I improperly shutting down my BIDS sessions? Is a save required for my code? Does "Build <component>" not automatically save?
Also, when I re-build a component after making a change to it, what do I need to do in my package's Data Flow task? Delete the current component, re-add it, and configure it again? I'm sure there are certain things that require one type of re-initialization vs. others (i.e., making a change to the Design Time code vs. making a change to code within the ProcessInput method.)
What can I do to properly register this now? I'm dead in the water and have no idea what to do. Any help's appreciated.
I developed a €œdata flow source€? in my computer and it is ready! It works in my computer, but how do I deploy this component in to the server? I have any programming environment on it. Any Idea?
I need to set variable during runtime in script component and then use it to create and fill new column in my Data Flow. So I'm using ReadWriteVariable of script component, and override PostExecute() method in ScriptMain where I set SSIS variable. Later in same data flow I need to use that variable to insert data into DB. However OLE DB Destination is not supporting parameters (I think) so I figured out that I'll use derived column and specify variable there and ADD AS NEW COLUMN. Then I map new columnt to proper field in DB and everything should be ok.
It is not. Variables are working really strange in SSIS. Derived Column is not taking variable at runtime but before execution. So my new columns are set to whatever I'll set in designer variables window at design time. Am i doing something wrong?
It would be very stupid to provide variables in Derived Column component if it is imposible to change their values at runtime. (I could do the same using constant in Derived Columna and Variables are not needed then)
I was trying the SSIS programming samples,that comes with installation of SQL Server 2005, I want to load the ChangeCase DLL in the toolbox.
The readMe file gives the direction. It does not work. It says you will see component in once you see DataFlow Task button( clicking Choose Items in the tools box).
I cannot load the custom component to the toolbox, Can I get some help.
in the acquireconnection method Using the below statment I can get a connection Object
oledbConnection = cmado.AcquireConnection(transaction) as OleDbConnection;
from the connection object I can get the connectionstring from the object by calling
oledbConnection.connectionstring() property which will have all the details like DataBase, UserName & other Inofrmation but there is no password Info.
How to get the password Information, I need that information since I will use that info to make OCI calls to fetch the data from the Oracle database in m,y custome source component.
Hi,I have developed a custom source component to get data from a generic odbc connection with some special caracteristics.
The component works fine by getting and mapping the output fields etc...
The only two problems existing are that when i run the task it says that the data flow has no components inside... how is this possible since i have my source mapped to a flat file inside that data flow?
This is the error:
SSIS package "BVEIT000D.dtsx" starting.
Warning: 0x80047034 at BVEIT000D_<EMPRESA> TXT, DTS.Pipeline: The DataFlow task has no components. Add components or remove the task.
Information: 0x4004300C at BVEIT000D_<EMPRESA> TXT, DTS.Pipeline: Execute phase is beginning.
SSIS package "BVEIT000D.dtsx" finished: Success.
The other problem is that if i want to <ignore> a certain source column the component already shows me an error saying that the no column with ID 0 was found...
Any one with experience in creating custom components?
Hi huys, can you tell me how you create a MSI file for your custom component.
basically i've created a SSIS custom component, and i want to distiribute among a few people, i guess instead of providing step by step instructions it would be easy if they just clicked on packaged msi file.
i've seen many people putting their custom components on the web as MSI, how do you do it?
Does anyone know how to get destination coulmns to show up in the advanced editor for a custom component? I have a custom flat file destination component that builds the output based on a specific layout. It works as long as the upstream column names match my output names. What I want is to allow non-matching columns to be mapped by the user as they can in a stock flat file destination. The closest that I have been able to come is to get the "column mappings" tab to show up and populate the "Available Input Columns" by setting ExternalmetadataColumnCollection.IsUsed to true on the input. The problem is that the "Available destination columns" box is always empty. I have tried the IsUsed property on the output and pretty much every other property that I could find. On the Input and Output properties all of my columns show up under the output as both External and Output columns. Is there a separate collection for "destination" columns that I can't find? It's getting a little frustrating, is this something that can be done or do I have to write a custom UI to make it happen?
