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 create a playlist of about 5 songs, although by a fairly roundabout route! First create a package called Playlist, and within this a data flow task which includes the following:
|What||What it does|
|Excel source||Import the 123 songs from the Excel workbook in the folder above.|
|Multicast transform||Duplicate this list of songs.|
|Row sampling transform||Sample 3 rows from the left-hand list.|
|Percentage sampling transform||Sample 1% of the rows from the right-hand list|
|Union all transform||Combine the two paths into one|
|Sort transform||Sort the songs so the one with the highest sales comes first|
|Union all transform||Add this, and put a data viewer on the data pipe leading to it so you can see which songs you've chosen!|
All of this is much easier to understand with a flow chart - for which read on!
Here's what your final package could look like, if you didn't give any of the transforms nice names:
A possible final flow chart for your package.
Here's what your playlist should look like (your songs will obviously be different):
A mix of styles here ...
Generate a couple of playlists, then close your package down.
