SQL Server Integration Services (SSIS) – Part 34 – Aggregate (COUNT) Transformations Control in SSIS


This is part 34 of the series of article on SSIS. In this article we are going to see on how to use an Aggregate (COUNT) data flow transformation control in SSIS packaging.


In this article we are going to see on how to use an Aggregate (COUNT) data flow transformation control in SSIS packaging. With this function operation we can get a Count on the number of rows necessary to get result in desired format. Let’s jump into to the example on how to use this control in real time.

You can look into my series of article on SSIS at the url - http://f5debug.net/tutorial/ssis.aspx



Follow steps 1 to 3 on my first article to open the BIDS project and select the right project to work on integration services project. Once the project is created, we will see on how to use an aggregate control for getting the count of the rows of a particular column or a list of columns.

Here we will see on the COUNT operation in the aggregate control. I have added an OLEDB connection which fetches the data from the database upon which we are going to do get the Count of number of rows and then pass it to a file destination as shown in the below screen


Here last 2 controls shows a red mark inside the control indicating that the control is not configured. We step forward and configure the same. Now double click on the Aggregate function will open a pop-up windows as shown in the below screen


Here we are selecting the columns on which we need a Count as shown in the screen. And after selecting the numbers of columns for getting the count now click on the OK button to get configured. Now configure the Flat File Destination as shown in the below screen.


Once everything is configured your screen will look as shown in the below screen


Now Hit F5 will run the application and show the output as shown in the below screen


Here the numbers of rows are indicated at the bottom of the each control as shown in the above screen. And finally the results (COUNT of rows) are loaded to flat file destination which looks like below



So in this article we have seen on how to get a count of number of rows using an Aggregate function transformation in data flow tab.
