Additional Schemas

Occasionally other schemas are required to run examples. These schemas are listed in the following sections.

Schema Objects Used in OraMetaData Examples

This section presents OraMetaData schema definitions.

CREATE TYPE ORAMD_ADDRESS AS OBJECT ( no NUMBER, 
                   street VARCHAR(60), 
                   state CHAR(2), 
                   zip CHAR(10), 
MEMBER PROCEDURE ChangeStreetName(newstreet IN VARCHAR2) 
); 

Schema Objects Used in LOB Data Type Examples

The following schema objects are used in the OraLOB and BFILE examples. Run the SQL script ORAEXAMP.SQL on your database to set up the schema.

CREATE TABLE part ( 
                   part_id NUMBER, 
                   part_name VARCHAR2(20), 
                   part_image BLOB, 
                   part_desc CLOB, 
                   part_collateral BFILE 
); 
 
Create Directory NewDirectoryName as 'C:\valid\path' 

Schema Objects Used in the OraObject and OraRef Examples

The following schema objects are used in the OraObject and OraRef examples. Data for the following tables can be inserted with the ORAEXAMP.SQL script that is provided with the OO4O installation.

CREATE TYPE address AS OBJECT (
                        street VARCHAR2(200),
                        city VARCHAR2(200),
                        state CHAR(2),
                        zip VARCHAR2(20)
);
 
CREATE TYPE person as OBJECT( 
                        name VARCHAR2(20), 
                        age NUMBER,
                        addr ADDRESS);
 
CREATE TABLE person_tab of PERSON;
CREATE TABLE customers(
                        account NUMBER,
                        aperson REF PERSON);

Schema Objects Used in OraCollection Examples

The following schema is used in examples of OraCollection methods

CREATE TYPE ENAMELIST AS VARRAY(20) OF VARCHAR2(30);
  CREATE TABLE department (
    dept_id NUMBER(2),
    name VARCHAR2(15),
    ENAMES ENAMELIST);

    DROP TYPE COURSE;

  CREATE TYPE Course AS OBJECT (
    course_no NUMBER(4), 
    title VARCHAR2(35),
    credits NUMBER(1));

  CREATE TYPE CourseList AS TABLE OF Course;

  CREATE TABLE division (
    name VARCHAR2(20),
    director VARCHAR2(20),
    office VARCHAR2(20),
    courses CourseList) 
  NESTED TABLE courses STORE AS courses_tab;
