The biggest difference between an INNER JOIN and an OUTER JOIN is that the inner join will keep only the information from both tables that’s related to each other (in the resulting table). An Outer Join, on the other hand, will also keep information that is not related to the other table in the resulting table.

The primary distinction between an INNER JOIN and an OUTER JOIN is that the inner join retains only the information from both tables that are related to each other (in the resulting table). An Outer Join, on the other hand, will keep information from the other table in the final table.
