Reuse Existing Data Flow Components In A Custom Data Flow Component
Aug 29, 2007Hello,
Is it possible to use existing data flow components (Merge Join, aggregation,...) in a custom data flow component?
Thanks,

Developing Custom Components By Extending The SSIS Stock Data Flow Components
Sep 7, 2006Everything 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.
Custom Data Flow Components, DllImport, And Third Party Dlls
Mar 29, 2007I'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.
Expression Editor On Custom Properties On Custom Data Flow Component
Aug 14, 2007Hi,
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, 2007Hi,
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()
{
ComponentMetaData.RuntimeConnectionCollection.RemoveAll();
RemoveAllInputsOutputsAndCustomProperties();
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 ?
Custom Data Flow Component Column Mapping Question
Feb 7, 2007Hi,
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.
cheers
SSIS Custom Data Flow Component - Variable Type Converter
Jun 27, 2007Hi all,
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;"
Data Flow Components
Nov 1, 2006Does 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.
Grouping Data Flow Components
Nov 15, 2007Hello 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.

Programmatically Iterating Tasks/components In The Data Flow Portion Of A Package.
Mar 6, 2007HI 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.
Data Flow Contains No Components After Package Save Operation And Reopening Solution
Jul 25, 2007I 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!!!
Custom Data Flow
Mar 26, 2007
To all the SSIS gurus,
I have a situation where I have multiple source tables, I need to populate the destination tables that have the same schema as the source ones. I dont want to do the repetitive task of creating a Dataflow for each source-destination load.
I want to create one custom dataflow component and loop through all my source tables and provide destination tables dynamically.
Is there a way to do that? Any custom data flow component out there??
Your ideas are greatly appreciated.

Need Help With Script Component In Data Flow
Jul 26, 2007I 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.
Xml Ssis Data Flow Component?
Jul 2, 2007There 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?
The Component Could Not Be Added To The Data Flow Task
Feb 6, 2007Dear 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,

This happens with EVERY custom component on my computer. The same components work fine on other machines.
Does anyone have an idea?

The Data Flow's Default Destination Component
Dec 10, 2007Is 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.
Using Variables In Data Flow Script Component
Jan 12, 2006I 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.
Passing Variables To Data Flow Component
Apr 27, 2006Hi,
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!
Data Flow Source Script Component
Dec 3, 2007I'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?

UnDoubleError Data Flow Component Problem
Oct 30, 2007
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...
What Does Strategy Exist To Deploy SSIS Package And My Own Data Flow Components Into A Enterparise Server?

SSIS Package Hangs In Data Flow, Magically Works After Opening And Closing Components
Nov 2, 2006We'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?
Updating Existing Table With Result Of Data Flow
Dec 4, 2007Hi,
I could use some help on how to save the result of my data-flow in an existing table.
I have created a data flow. I have no trouble storing the result of the flow in a new table. But I'm trying to store the result of my data flow in an existing table. (The flow involves fuzzy grouping, and i would like to store the result in the original table on which the fuzzy grouping was performed). But I cannot get it to work.
I can select the existing table as OLE DB destination. I can write an SQL to manipulate this table, but how do i address the result of the flow in the SQL?
Help is welcome here!

View 5 Replies View RelatedUsing Expressions In Custom Data Flow Transformation
Sep 18, 2006Hi,
I'm creating a custom data flow transformation in c#.
I would like to use expressions within this component in the same way as in the derived column component: specifying the expression as a custom property of an output column, then evaluating this expression for each row of the buffer and using this evaluated expression to populate my output column values.
So I've added an custom expression on my output column, and set its expression type to CPET_NOTIFY
IDTSCustomProperty90 exp = col.CustomPropertyCollection.New();
exp.Name = "Expression";
exp.ExpressionType = DTSCustomPropertyExpressionType.CPET_NOTIFY;
But in the ProcessInput method I don't manage to get the evaluated expressions, when I use exp.Value I get my expression definition and not its evaluation.
Is there a way to get these evaluated expressions ?
Thanks,

How To Connect To Oracle In A Script Component In A Data Flow
Nov 9, 2007Hi
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.

Logging Data Flow Component Events In SSIS
Nov 14, 2007Does 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.
