This video explains how to use left and right outer joins in your SQL queries for Excel files. You'll learn why inner joins don't always return all the results you expect and how to use an outer join to ensure that you always return all of the rows from one of the tables involved in the join. You'll see how to use criteria to find the unmatched rows from a table and find all the invalid entries in a joined table.
See our full range of VBA training resources, or test your knowledge of VBA with one of our VBA skills assessment tests.
