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.

Create a new database called Credit Control 2.mdb.

Import data from the Excel file in the folder shown above to create 2 new tables:

  • AgedDebt, holding the outstanding debt figures by account number; and
  • Accounts, showing details for each account

Create a query using ad hoc joins to show that there are two groups in the Accounts table with no corresponding AgedDebt figures:

The two groups not referenced

Create a separate query showing that there are 3 accounts with aged debt information which do not have corresponding entries in the Accounts table:
