If Cross join is also called as wrong join then why we have to go for cross join?
what is the purpose of cross join? is it useful inside query part?
There are very of few or you can say none scenario which requires cross join. For me, its the result of users inefficiency of generating conditions which result in oracle to decide and generate all possible outcome.
Cross join just gives all the possible outcomes,many to many mapping between the two tables.
