Inner Join

An Inner Join is a way to combine data from two related tables based on a common piece of information they share, such as an ID or name. It creates a new set that includes only the records where there is a match in both tables. Think of it like connecting two lists with a common column, and only seeing the entries that appear on both lists. This method is useful for finding related information, like matching customer details with their orders, and excludes any entries that don’t have a match in both tables.
