oracle数据库,插入数据
oracle database, insert data
我正在使用 Oracle 11g table:
create or replace type address as object (
street varchar2(20),
city varchar2(10),
p_code varchar2(8)
) not final;
/
create or replace type name as object (
title varchar2(5),
firstName varchar2(8),
surname varchar2(8)
) not final;
/
create or replace type phone as object
(
homePhone int,
mobile1 int,
mobile2 int
) not final;
/
create or replace type person as object (
pname name,
pAddress address,
Pphone phone
) not final;
/
create or replace type employee under person (
empId varchar2(5),
position varchar2(16),
salary int,
joinDate date,
supervisor ref employee);
/
create table tb_employee of employee
(
primary key(empID)
)
/
我插入的数据
insert into tb_employee values
(
person(name('mr','jone','smith'),address('street','city','post
code'),phone('11111111111','22222222222','33333333333')),
position('head'),
salary(1111),
joinDate(12-Feb-1994),
empID('001')
)
insert into tb_employee values
(
person(name('mr','jane','smith'),address('street','city','post
code'),phone('11111111111','22222222222','33333333333')),
position('accountant'),
salary(2222,
joinDate(13-Feb-1995),
empID('002')
)
insert into tb_employee values
(
person(name('miss','ross','smith'),address('street','city','post
code'),phone('11111111111','22222222222','33333333333')),
position(manager),
salary(333),
joinDate(14-Feb-1996),
empID('003')
)
我想通过引用函数向数据中插入主管,
例如:
负责人 (jone smith) 是主管或经理 (miss ross smith),
经理(罗斯·史密斯小姐)是客户主管(简·史密斯先生),
谢谢!
您正在插入 employee
类型的记录:适用于 整个记录 因此您需要编写一个匹配该类型投影的 VALUES 子句。
要填充 REF 子句,您需要 select 相关对象的引用。您的第一条记录没有主管,因此在这种情况下我们传递 NULL:
insert into tb_employee values
( employee(
name('mr','jone','smith')
, address('street','city','postcode')
, phone('11111111111','22222222222','33333333333')
, '001' -- emp id
, 'head' -- position
, 11111 -- salary
, to_date('12-Feb-1994','dd-mon-yyyy') -- joinDate
, null-- supervisor
))
/
对于其他记录,我们使用 INSERT ... SELECT ... FROM 语法:
insert into tb_employee
select
employee(
name('mr','jane','smith')
, address('street','city','postcode')
, phone('11111111111','22222222222','33333333333')
, '002' -- emp id
, 'accountant' -- position
, 2222 -- salary
, to_date('13-Feb-1995','dd-mon-yyyy') -- joinDate
, ref (m) -- supervisor
)
from tb_employee m
where m.empid = '001'
/
insert into tb_employee
select
employee(
name('miss','ross','smith')
, address('street','city','postcode')
, phone('11111111111','22222222222','33333333333')
, '003' -- emp id
, 'manager' -- position
, 333 -- salary
, to_date('14-Feb-1996','dd-mon-yyyy') -- joinDate
, ref (m) -- supervisor
