Queries VII: Query multiple sources for data

Learn how to query multiple data sources

Learn how to create a query that takes data from two or more sources — tables or queries. You'll probably need to query multiple sources more than you will single tables or queries. The key to doing that is making sure you can join, or associate, the fields in the tables or queries in your record source.
