Update statement for object table.

Question

Hi,
I have created one type as
Create type test as object(
ins_by varchar2(30),
ins_on date,
upd_by varchar2( 30),
upd_on date);
and then created an object table as
create table imst(
i_code number(5),
i_desc varchar2(35),
i_op test);
now i am able to insert record in this table as
insert into imst values(1,'Hawkins cooker',test(user,sysdate,'',''));
Above works fine.
But I would also like to update the record with i_op.upd_by,i_op.upd_on with some other values.
Can any body help me specifying how to write a plain update statement for the same.
Regards.

Check it out:
SQL> Create type myTest as object(
  2  ins_by varchar2(30),
  3  ins_on date,
  4  upd_by varchar2( 30),
  5  upd_on date);
  6  /
Type created.
SQL> create table imst(
  2  i_code number(5),
  3  i_desc varchar2(35),
  4  i_op myTest);
Table created.
SQL> insert into imst values(1,'Hawkins cooker', mytest(user,sysdate,'',''));
1 row created.
SQL> select * from imst;
    I_CODE I_DESC
I_OP(INS_BY, INS_ON, UPD_BY, UPD_ON)
         1 Hawkins cooker
MYTEST('APC_LOAD', '12-JUL-04', NULL, NULL)
SQL> update imst i set i.i_op.upd_by = USER, i.i_op.upd_on = add_months(sysdate, 1);
1 row updated.
SQL> select * from imst;
    I_CODE I_DESC
I_OP(INS_BY, INS_ON, UPD_BY, UPD_ON)
         1 Hawkins cooker
MYTEST('APC_LOAD', '12-JUL-04', 'APC_LOAD', '12-AUG-04')
