Example:

select * bulk collect into my_temp_storage from student;

Question:

If the temporary table ever created on the hard disk and the data is written?

Or you can let everything run in memory?

Thank you!

Do it with a very big table and you will see the error "ORA-04030: out of process memory when trying to allocate %s bytes".
