oracle觸發器加條件判斷、dblink

--新增基站同步給電池組信息
create or replace trigger a_b_test
  after  insert or update or delete
  on BJLT.BASESTATION 
  --REFERENCING NEW AS new_val OLD AS old_val --在這里設置名字,然后可引用新值,舊值

dblink情況下，新增本地表，同步遠程服務器另一張表

參考自：http://www.blogjava.net/hhhaaawwwkkk/archive/2009/05/06/269251.html

參考內容：

---創建dblink,dblink_test名稱，（被同步數據庫的a_test）ST10766用戶名，ep密碼，ass100連接字符串
create public database link dblink_test
　　 connect to ST10766 identified by ep
　　 using 'ass100';

---刪除dblink
----drop public database link dblink_test;

----建立表
create table a_test (id int,name varchar(20),pass varchar(20))
select * from a_test;

insert into a_test (id,name,pass) values (1,'zzn','shanshan')
insert into b_test (id,username,password) values('1','zxl','xiaolan')

----在目的數據庫上，測試dblink，查詢的是源數據庫的表
select * from a_test@dblink_orc10; 
select * from a_test;

----創建觸發器

create or replace trigger a_b_test
  after  insert or update or delete
  on a_test
  for each row
begin
  if deleting then
      delete from b_test where id=:old.id;
  end if;
  if inserting then
      insert into b_test(id,username,password)  //b_test表的字段
      values(:new.id,:new.name,:new.pass); //a_test表的字段
  end if;
  if updating then
     update b_test set username=:new.name,password=:new.pass where id=:old.id;
  end if;
end a_b_test;
