SSIS Integration Services | Previous versions exercise | A Script Task to count X Factor series and advise Simon
This exercise is provided to allow potential course delegates to choose the correct Wise Owl Microsoft training course, and may not be reproduced in whole or in part in any format without the prior written consent of Wise Owl.
You can learn how to do this exercise on the relevant Wise Owl classroom training course (sadly for the moment only in the UK).
You need a minimum screen resolution of about 700 pixels width to see our exercises. This is because they contain diagrams and tables which would not be viewable easily on a mobile phone or small laptop. Please use a larger tablet, notebook or desktop computer, or change your screen resolution settings.
Create a package called Simon Says, which will count how many series have been made so far and then offer suitable advice to Simon Cowell on whether to make another. Within this new package, create a couple of variables:
We've tentatively set the maximum permissible number of series to 10. Some may think one was too many ...
Create a data flow task, and set the source to be the Series worksheet in the workbook in the folder above:
What you should see when you preview the results in the Excel source.
Now add a Row Count transform on so that the data flow task looks like this:
Store the number of rows in your NumberSeriesMade variable.
Create 3 script tasks as follows to control what happens next:
The first task should end in success or failure, depending on whether we've exceeded the maximum number of permissible series yet. The other two tasks should display suitable messages in either case.
Try running the package with the MaximumNumber variable set to 10 and then 7 (say). You should see messages something like this:
|The first message||The second message|
Again, note that this is NOT the quickest way to solve this problem!
Close your package down.
