In this video, we will show you the different special joins you can use in PostgreSQL such as Natural Join, Cross Join, and Self Join. Natural join in PostgreSQL combines tables based on their common columns, automatically matching columns with the same name in both tables. Cross join, on the other hand, does not have a join predicate and creates a Cartesian product by combining every row from one table with every row from another table. Self join in PostgreSQL involves joining a table to itself and is useful for comparing or retrieving related data from different rows within the same table.
