When designing an Access query it can be simple or more complex. In Access complex query guidlines let you do more with data.
In the previous lesson, you learned how to create a simple query with one table. Most queries you design in Access will likely use multiple tables, allowing you to answer more complex questions. In this lesson, you'll learn how to design and create a multi-table query.
Throughout this tutorial, we will be using a sample database. If you would like to follow along, you'll need to download our Access 2013 sample database. You will need to have Access 2013 installed on your computer in order to open the example.
Queries can be difficult to understand and build if you don't have a good idea of what you're trying to find and how to find it. A one-table query can be simple enough to make up as you go along, but to build anything more powerful you'll need to plan the query in advance.
When planning a query that uses more than one table, you should go through these four steps:
This process might seem abstract at first, but as we go through the process of planning our own multi-table query you should start to understand how planning your queries can make building them a lot easier.
