oracle創建sequence和觸發器trigger

1、創建sequence

create sequence JEECG.SEQU_NT_PLFBGCSJB_ID
minvalue 1
maxvalue 9999999999999999999999999999
start with 1
increment by 1
cache 20
order;

2、觸發器trigger

   create or replace trigger TRIG_PLFBGCSJB_ID
  before insert on NT_PLFBGCSJB
  for each row
declare
  -- local variables here
begin
  select SEQU_NT_PLFBGCSJB_ID.nextval into :new.id from dual;
end TRIG_PLFBGCSJB_ID;
