Loading a Table with a VARRAY in It: INSERT VALUEs with Constants

Oracle's VARRAYs behave like classes in object-oriented programming.

Classes are instantiated into objects using constructors.

SQL>
SQL> CREATE OR REPLACE TYPE mem_type IS VARRAY(10) of VARCHAR2(15)
  2  /

Type created.

SQL>
SQL> CREATE TABLE club (Name VARCHAR2(10),
  2  Address VARCHAR2(20),
  3  City VARCHAR2(20),
  4  Phone VARCHAR2(8),
  5  Members mem_type)
  6  /

Table created.

SQL>
SQL> INSERT INTO club VALUES ('AL','111 First St.','Mobile',
  2  '222-2222', mem_type('Brenda','Richard'));

1 row created.

SQL>
SQL> INSERT INTO club VALUES ('FL','222 Second St.','Orlando',
  2  '333-3333', mem_type('Gen','John','Steph','JJ'));

1 row created.

SQL>
SQL> SELECT *
  2  FROM club;
