Use a dynamic connection to loop over Excel workbooks, combining their rows into a SQL Server table

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.

Before you can do this exercise, you'll need to download and unzip this file .

In Management Studio, open the SQL script in the above folder and execute it to generate an empty table:

Your package should fill this table!

The idea is to combine data from the three workbooks in this folder into a single table:

The final result your package should produce: a list of songs in the original empty SQL Server table imported from each of the Excel workbooks in the above folder.

Start by creating a package called Something for everyone which looks like this:

To start with, just get the data flow task to import the Anyone.xlsx data into your Playlist table (we'll worry about changing this file in a moment).

When you run this package, you should get a bit of repetition:

Adele is good, but not THAT good - we've imported rows from the same workbook 3 times over.

Now change the properties of your Excel connection manager so that the connection is an expression whose value changes each time round the loop:

Much better!

How much energy do you still have left? You could always add a derived column transform within the data flow task to generate the target market column value. Here's a suggestion for the (horrible) expression you could use:

REPLACE(RIGHT(@[User::FilePath],
FINDSTRING(REVERSE(@[User::FilePath]),
"\\",1) - 1),".xlsx","")

And now it's definitely time to close the package down!

You can unzip this file to see the answers to this exercise, although please remember this is for your personal use only.
