Setting Up the Database
This tutorial uses a database schema with a single table called PRODUCT. Use your own database system tools to create the table, using the following SQL statements as a model. The statements are based on Oracle syntax.
PARTS_T Type
CREATE TYPE PARTS_T AS OBJECT (
PARTNO INTEGER NOT NULL,
PARTNAME VARCHAR(20) NOT NULL)
PARTS_TABLE_T Type
CREATE TYPE PARTS_TABLE_T AS TABLE OF PART_T
PRODUCT Table
CREATE TABLE PRODUCT (
PRODNO INTEGER NOT NULL,
PRODNAME VARCHAR(50) NOT NULL,
PARTS PARTS_TABLE_T,
PRIMARY KEY (PRODNO))
The column PARTS in the PRODUCT table contains the nested tables.
The PRODUCT table contains the following data:
PRODNO | PRODNAME | PARTS |
