Answer Posted / Kaptan Singh
Cross join, also known as a cartesian product, is used in SQL to combine all rows from two or more tables with no regard for the relationship between them. It can be useful when you want to find combinations of all possible values from each table. However, due to its potential to produce a large result set quickly, it should be used carefully and sparingly.
