基于Oracle触发器存储过程

先说下需求,有一套表触发器监听这一套表的增删改,并记录操作到监听记录表中City_cfjlb

触发器:

create or replace trigger Tri_city_scsbxxb_Change --
  after delete or update or insert on city_scsbxxb --
  for each row
declare
  -- kid       number;
  cfsj      date;
  tableName VARCHAR2(50);
  sjId      VARCHAR2(50);
  czlx      VARCHAR2(50);

begin
  tableName := 'city_scsbxxb'; --
  sjId      := 'city_scspxxid=' || :OLD.city_scspxxid; --

  --select S_CITY_CFJLB.Nextval into kid from dual;
  select sysdate into cfsj from dual;

  CASE
    WHEN UPDATING THEN
      czlx := 'E';
    WHEN INSERTING THEN
      sjId      := 'city_scspxxid=' || :NEW.city_scspxxid; --
      czlx := 'A';
    WHEN DELETING THEN
      czlx := 'D';
  END CASE;
  Copy_City_BZTOMY(tableName, czlx, cfsj, sjId);
end Tri_city_scsbxxb_Change;

存储过程:

create or replace procedure Pro_Copy_City(Cfbmc  in City_Cfjlb.Cfbmc%type,
                                             Cflx   in City_Cfjlb.Cflx%type,

        dbms_output.put_line(v_sql);
    EXECUTE IMMEDIATE v_sql
      INTO K_ID;
  end if;
  if Cflx = 'D' then

     EXECUTE IMMEDIATE v_sql2;
  end if;
  if K_ID > 0 then
    UPDATE CITY_CFJLB
       SET KID = s_CITY_CFJLB.Nextval, CITY_CFJLB.CFSJ = Cfsj
     where KID = K_ID;
  else
    INSERT INTO CITY_CFJLB city

      (s_CITY_CFJLB.Nextval, Cfbmc, Cflx, cfsj, Cfsjid, '0');
