有多少cars for all departments.
create or replace type CARTYPE as object
(
VIN NUMBER(17),
YEAR NUMBER(4),
MODEL VARCHAR2(60)

create or replace type CARTABLETYPE as table of CARTYPE;
/
create table Dept(
deptID integer constraint dept_pk primary key,
dname char(20) not null,
cars CartableType
)
nested table cars store as Cartable;
然后我用：
select sum(count(c.*)) from dept D,table(d.cars) c; |
