PL/SQL and User Defined Types.....

Question

Hi All,
I defined TEST_1 User Defined Type where VALUE_PART field is a VARCHAR2 type.
TEST_1 is placed under sys so that everyone can use this type in Oracle 9i.
CREATE TYPE TEST_1 AS OBJECT (
VALUE_PART VARCHAR2(50),
x NUMBER,
y NUMBER
This TEST_1 object type will be used as nested tables in the EMPLOYEE table where each attribute might require different bytes of VARCHAR2’s in the VALUE_PART field.
CREATE TYPE NAME AS TABLE OF TEST_1;
CREATE TYPE ADDRESS AS TABLE OF TEST_1;
CREATE TYPE DEPARTMENT AS TABLE OF TEST_1;
CREATE TABLE EMPLOYEE (
SSN NUMBER,
NAME TEST_1,
ADDRESS TEST_1,
DEPARTMENT TEST_1,
SALARY NUMBER
NESTED TABLE NAME STORE AS NAME_TABLE;
NESTED TABLE ADDRESS STORE AS ADDRESS_TABLE;
NESTED TABLE DEPARTMENT STORE AS DEPARTMENT_TABLE;
Is it possible to specify VALUE_PART in the TABLE OF statement with different number of bytes?
Is there any way to do that through methods or some other ways that I may not be aware of?
For Example:
/*This should allocate 10 bytes of VARCHAR2. */
CREATE TYPE NAME AS TABLE OF TEST_1(10);
/* and 30 bytes of VARCHAR2. */
CREATE TYPE ADDRESS AS TABLE OF TEST_1(30);
/*and 10 bytes of VARCHAR2. */
CREATE TYPE DEPARTMENT AS TABLE OF TEST_1(10);
Any help is appreciated.
Thanks a lot.

this type in Oracle 9i.that's just wrong on sooo many levels. don't EVER put anything in sys.
put it under an appropriate user, grant it, even create a synonym for it.
and how would putting it under sys make it "so that everyone can use" it? unless you put everything else under sys as well.
