This video explains how to write inner joins in your SQL queries for Excel files to look up related information in different worksheets. You'll learn a bit about relational database design including what primary keys, foreign keys and one-to-many relationships are. You'll see how to join two tables using an inner join to match rows based on a common value. You'll see an alternative way to do the same thing without using an inner join. You'll also learn the syntax required to include multiple tables in the same query and finally how to apply criteria and sorting to the results.
This video has the following accompanying files:
|Inner Joins.xlsm||Excel workbook with macros||The query code|
