Solution

The SQL INNER JOIN retrieves only the matching rows between two tables. This means it will only return the records where there is a match in both tables based on the condition specified in the JOIN clause. If there is a record in the first table that does not have a corresponding match in the second table, it will not be included in the result set, and vice versa.
