create table orderinfo
( order_id integer primary key,
salary number(5) not null)；
create table smallorder

salary number(5) not null)；
create table largeorder
( order_idinteger primary key,
salary number(5) not null)；
create table specialorder
( order_id integer primary key,
salary number(5) not null)；
insert into orderinfo values(1, 100);
insert into orderinfo values(2, 600);
insert into orderinfo values(3, 700);
insert into orderinfo values(4, 200);
insert into orderinfo values(5, 300);
select * from orderinfo；
21.2. 同時插入多個表
insert all
into smallorder values(order_id,salary)
into largeorder values(order_id,salary)
select * from orderinfo;
21.3. 同時插入多個表(帶條件)
insert all
when salary >= 0 and salary < 300then
intosmallorder values(order_id,salary)
when salary >= 700 then
into specialorder values(order_id,salary)
when salary >= 300 then
intolargeorder values(order_id,salary)
select * from orderinfo; --700同時插入largeorder表和specialorder表
21.4. insert first
when salary >= 0 and salary < 300then
intosmallorder values(order_id,salary)
when salary >= 700 then
intospecialorder values(order_id,salary)
when salary >= 300 then
intolargeorder values(order_id,salary)
select * from orderinfo; --700只插入specialorder表，與條件語句的順序有關
select * from smallorder;
select * from largeorder;
select * from specialorder
