In this movie, Adam demonstrates how to create a Find Unmatched query manually in the query design view. By changing the join properties between two related tables, all of the records from the parent table can be revealed. Adding an "is null" criteria on a related field limits the records to just those that are unmatched.

Let's go back into Design View.…Now previously we saw that if we…modify the join line between these two tables…we have some different options.…I'll double click on the line…to bring up the Join Properties window…and the default option is to only…include rows where the join fields…
