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 read in a shopping list and calculate the total amount of money it will cost to buy:

Shopping list to read in Final message to display
The shopping list What the package should show

To get started, run the script in the above folder to create a table called tblList, then create a package called Aldi or Waitrose.

Create the following variables (strictly speaking you don't need the last one):

Variables for shopping list

The ShoppingList variable will hold the table records.

Now create the control tasks to make this work:

Control flow for shopping list

The SQL script to begin should be something like SELECT ItemName, Quantity, Pence FROM tblList.

 

Here's the script you could use:

// display total value of all items (price * quantity)

decimal TotalValue = Convert.ToDecimal(

Dts.Variables["TotalValue"].Value);

 

MessageBox.Show("Total value of all items is £" +

(TotalValue/100).ToString("#,##0.00"),"Shopping list");

Test that this package gives £8.14 when run as the total!
