oracle中表insert or update or delete觸發器

在一個表（User_Info_2017 ）上放置一個觸發器；

當對它進行insert，update，delete的操作時，觸發器（UserToTemp ）啓動，

把相應的變動數據根據需要放到另外一個表（User_Info_2017_temp ）中；

觸發器代碼如下：

create or replace trigger UserToTemp after insert or update or delete
on User_Info_2017 for each row
declare
    integrity_error exception;
    errno            integer;
    errmsg           char(200);
    dummy            integer;
    found            boolean;

begin
if inserting then
    insert into User_Info_2017_temp(ID,UserName,PassWord,CreateDate,Status) values(:NEW.ID,:NEW.UserName,:NEW.PassWord,:new.CreateDate,:NEW.Status);
elsif updating then
    update User_Info_2017_temp set ID=:NEW.ID,UserName=:NEW.UserName,PassWord=:NEW.PassWord,Status=:NEW.Status where id=:OLD.id;
elsif deleting then
    delete from User_Info_2017_temp where id=:OLD.id;
end if;
exception
    when integrity_error then
       raise_application_error(errno, errmsg);
end;
