oracle触发器与数据导入导出的简单使用

exp cjtxx/123456@192.168.80.231/orcl file=d:\cjtxx.dmp owner=cjtxx [tables=tablename]

imp cjttest/123456@192.168.80.231/orcl file=d:\cjtxx.dmp full=y 

insert into bdf2_user_position(id_,position_id_,username_) values(:new.username_,'ptjs',:new.username_);

　　触发器根据新插入的表记录，新增另一条表信息

create or replace trigger test
  after insert on bdf2_user  
  for each row
declare
  -- local variables here
begin
  insert into bdf2_user_position(id_,position_id_,username_) values(:new.username_,'ptjs',:new.username_);
end test;
