This video demonstrates how to use the IN clause (not to be confused with the IN operator!) in an ADODB SQL query to select data from multiple files in the same query. You'll learn how to union tables from multiple Excel workbooks, both with and without header rows. As a bonus, you'll also see how to union data from a CSV file.
