Joins exercise
Harder than average exercise

This Microsoft Access JOINS exercise is provided to allow potential course delegates to assess their suitability for the Wise Owl BASIC QUERYING IN ACCESS course only, and may not be reproduced in whole or in part in any format without the prior written consent of Wise Owl.

Exercise: Credit control - deleting unmatched accounts

A full answer to this exercise is provided as part of the training course!

1)	Download the files needed to start this exercise: exercise-517.zip (and click here if you experience any problems unzipping this file after downloading it).
2)	You already have a query called GroupNamesNotUsed, which lists out all of the group names in the Accounts table not used in the AgedDebt table.
3)	Create a query called DeleteUnusedGroups which will delete any such groups not being used from the Accounts table.
Start by creating a query linking the Accounts table with the DeleteUnusedGroups query, then make this a Delete query.
4)	Save and close this query.

Thank you for showing an interest in this Basic Querying in Access training course! As mentioned above, full answers to this and other exercises are provided on the course. On all Wise Owl scheduled courses delegates can take away these model answers (together with their own efforts!) on a free USB stick.
