It forms the foundation for understanding the following chapters which will go into detail about how SQL commands are applied ignored. Tip The ARRAY constructor syntax (see Section 4.2.12) is often easier to work with than the ar- ray-literal syntax when writing array values in SQL commands. In ARRAY, individual element values
