Before you can do this exercise, you'll need to download and unzip this file (if you have any problems doing this, click here for help).

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.

The aim of this exercise is to import the X Factor contestants (again!), storing for each their category number.  Here's what the final tblFinalist table should look like:

List of finalists imported

The final table of finalists (shown here in reverse alphabetical order).

Begin by deleting any existing tables called tblCategory or tblFinalist from your X_Factor database, then run the SQL script in the above folder.

List of categories

What you should now see in the tblCategory table. All contestants with unknown categories will be assigned the value 5.

 

Create a variable called UnknownCategoryId to hold the number 5 above (it's better practice to store this in a variable, so we can change it easily).

Optionally create a task to truncate the table of finalists (so that you can rerun the package several times), then create a data flow task looking something like this:

Final data flow with lookup

As this shows, there are 32 contestants with no corresponding category name.

 

When you're happy this is all working OK, give yourself a pat on the back!
