Hi experts, I am a teacher and I am supposed to teach PL/SQL to my students. I am referring a book 'PL/SQL by Ivan byross'. I am right now reading cursor topic. I read following paragraph about cursor in the book and I am not able to understand meaning of it. Please help me to make it clear. "If the number of rows returned by oracle engine is more than the area available in the cursor opened on the client, the cursor data and the retrieved data is swapped between the operating system's swap area and RAM"
