What type of join results in the entire table being scanned?

The correct answer is based on the nature of the join operation. A join operation merges records from two or more tables based on a related column between them. While specific types of joins like Inner Join and Outer Join efficiently filter records according to specific criteria, there is a specific join known as Cross Join that leads to an entire table being scanned.

In a Cross Join, each row from one table is combined with every row from another table, leading to a Cartesian product. This kind of operation will result in a substantial amount of data, as the number of resultant rows will be the product of the number of rows in each participating table. Since a Cross Join does not have any filtering criteria to limit which records to include based on matches, every record from both tables is considered, necessitating a full scan of both tables.

While it might seem that other types of joins could also lead to a substantial number of records being processed, they typically apply filtering conditions that would prevent the complete scan of tables. Therefore, the Cross Join is the most relevant to the question asked about a join type resulting in an entire table being scanned. The reasoning behind choosing "All Join" could stem from a misunderstanding of the implications of different joins and how they process data, but in
