I have an problem with my homework. I have the following type definitions:
-- Type definitions
CREATE OR REPLACE TYPE languages_table_t AS TABLE of VARCHAR2(20);
/
CREATE OR REPLACE TYPE phones_table_t AS TABLE of NUMBER;
/
CREATE OR REPLACE TYPE tourist_t AS OBJECT (
-- ...
-- some simple attrubutes
-- one attribute of user defined type
-- more simple attrubutes
-- ...
) NOT FINAL;
/
CREATE OR REPLACE TYPE guide_t UNDER tourist_t (
languages languages_table_t,
phones phones_table_t
);
/
-- All types are created successfully
-- table definitions:
CREATE TABLE Tourist OF tourist_t (
-- all simple attributes with nullity constraints
CONSTRAINT PK_TOURIST PRIMARY KEY (username),
) NESTED TABLE the_UDT_attr STORE AS the_user_defined_type;
-- Created successfully
CREATE TABLE Guide OF guide_t (
CONSTRAINT PK_GUIDE PRIMARY KEY (username)
) NESTED TABLE languages STORE AS guide_languages
NESTED TABLE phones STORE AS guide_phones;
-- returns mystic error
when running the last create instruction, I get the following error:
CREATE TABLE Guide OF guide_t (
*
ERROR at line 1:
ORA-22913: must specify table name for nested table column or attribute
I've searched for this error, but it seems too specific to my definitions, and I couldn't find how to solve it. Please, any help will be appreciated. I need an idea about how to attack these kind of errors, how to solve them or where to read about it.
