Answer 1

CREATE OR REPLACE TYPE dob_date AS OBJECT(
DAY NUMBER,
MONTH VARCHAR2(12),
YEAR NUMBER
drop type dob_date
CREATE OR REPLACE TYPE names AS OBJECT(
fname VARCHAR2(10),
mname VARCHAR2(10),
lname VARCHAR2(10)
create table employee_details (Emp_no number,name names,dob dob_date,manager_name varchar2(15),
sal number,dept_name varchar2(10));
insert into employee_details values(1,names('Sankara','narayanan','C'),dob_date(26,'MAY',1985),'manager',12312,'maths');
update employee_details ed set ed.name.lname='Sank' where emp_no=1;
update employee_details ed set ed.dob.DAY='27' where emp_no=1;
updated sucessfully
use the column name to refer...not the type name
Thanks
