Table functions are very cool: they are functions that return collections, and can be called in the FROM clause of a SELECT, as if it were a table or view. In this session, Steven Feuerstein starts with a quick intro to and demos of table functions. We then shift to answering your questions on this useful feature, including (new to 18c) polymorphic table functions and interactions between table functions and the SQL optimizer.
