As the name suggests we have taken the current Row Count Transform that is provided by Microsoft in the Integration Services toolbox and we have recreated the functionality and extended upon it. There are two things about the current version that we thought could do with cleaning up
- Lack of a custom UI
- You have to type the variable name yourself
In the Row Count Plus Transformation we solve these issues for you.
Another thing we thought was missing is the ability to calculate the time taken between components in the pipeline. An example usage would be that you want to know how many rows flowed between Component A and Component B and how long it took. Again we have solved this issue.
Credit must go to Erik Veerman of Solid Quality Learning for the idea behind noting the duration. We were looking at one of his packages and saw that he was doing something very similar but he was using a Script Component as a transformation. Our philosophy is that if you have to write or Copy and Paste the same piece of code more than once then you should be thinking about a custom component and here it is.
The Row Count Plus Transformation populates variables with the values returned from;
- Counting the rows that have flowed through the path
- Returning the time in seconds between when it first saw a row come down this path and when it saw the final row.
It is possible to leave both these boxes blank and the component will still work.
All input columns are passed through the transformation unaltered, you are not permitted to change or add to the inputs or outputs of this component.
Optionally you can set the component to fire an event, which happens during the PostExecute phase of the execution. This can be useful to improve visibility of this information, such that it is captured in package logging, or can be used to drive workflow in the case of an error event.
|Property ||Data Type ||Description |
|OutputRowCountVariable ||String ||The name of the variable into which the amount of row read will be passed (Optional). |
|OutputDurationVariable ||String ||The name of the variable into which the duration in seconds will be passed. (Optional). |
|EventType ||RowCountPlusTransform.EventType ||The type of event to fire during post execute, included in which are the row count and duration values. |
|Name ||Value ||Description |
|None ||0 ||Do not fire any event. |
|Information ||1 ||Fire an Information event. |
|Warning ||2 ||Fire a Warning event. |
|Error ||3 ||Fire an Error event. |
The component is provided as an MSI file which you can download and run to install it. This simply places the files on disk in the correct locations and also installs the assemblies in the Global Assembly Cache as per Microsoft’s recommendations.
You may need to restart the SQL Server Integration Services service, as this caches information about what components are installed, as well as restarting any open instances of Business Intelligence Development Studio (BIDS) / Visual Studio that you may be using to build your SSIS packages.
For 2005/2008 Only - Finally you will have to add the transformation to the Visual Studio toolbox manually. Right-click the toolbox, and select Choose Items.... Select the SSIS Data Flow Items tab, and then check the Row Count Plus Transformation in the Choose Toolbox Items window. This process has been described in detail in the related FAQ entry for How do I install a task or transform component?
We recommend you follow best practice and apply the current Microsoft SQL Server Service pack to your SQL Server servers and workstations, and this component requires a minimum of SQL Server 2005 Service Pack 1.
The Row Number Transformation is available for SQL Server 2005, SQL Server 2008 (includes R2) and SQL Server 2012. Please choose the version to match your SQL Server version, or you can install multiple versions and use them side by side if you have more than one version of SQL Server installed.

Make sure you have downloaded the version that matches your version of SQL Server. We offer separate downloads for SQL Server 2005, SQL Server 2008 and SQL Server 2012.
If you get an error when you try and use the component along the lines of The component could not be added to the Data Flow task. Please verify that this component is properly installed. ... The data flow object "Konesans ..." is not installed correctly on this computer, this usually indicates that the internal cache of SSIS components needs to be updated. This is held by the SSIS service, so you need restart the the SQL Server Integration Services service. You can do this from the Services applet in Control Panel or Administrative Tools in Windows. You can also restart the computer if you prefer. You may also need to restart any current instances of Business Intelligence Development Studio (BIDS) / Visual Studio that you may be using to build your SSIS packages.
Once installation is complete you need to manually add the task to the toolbox before you will see it and to be able add it to packages - How do I install a task or transform component?
