oracle怎样用触发器将一张表的数据添加到另外一张表中

好吧，我就假设你两个表的数据结构相同吧
create table  TabA
(
     address varchar2(50),
     press varchar2(50),
     city  varchar2(50) 
)
/
create table  TabB
(
     address varchar2(50),
     press varchar2(50),
     city  varchar2(50) 
)
/

create or replace trigger addData
after insert 
on tabA 
begin
insert into tabB  select * from tabA;
end
插入测试语句
insert into tabA values ('123','123','123');
