oracle触发器和序列迁移至达梦如何实现自增？

原oracle主键使用序列加触发器实现自增，如下：

create sequence USER1.SEQ_TEST
minvalue 1
maxvalue 999999999999999
start with 600
increment by 1
cache 20;

CREATE OR REPLACE TRIGGER USER1.TR_TEST
BEFORE INSERT ON USER1.TEST
for each row
where (NEW.ID is NULL)
begin
  select USER1.SEQ_TEST.Nextval into :NEW.ID from dual;
end;

迁移至达梦后，如下：

create sequence "USER1"."SEQ_TEST"
INCREMENT BY 1
START WITH 630
MAXVALUE 999999999999999
NOCYCLE
CACHE 20
NOORDER;

create or replace trigger "USER1"."TR_TEST"
before INSERT 
on "USER1"."TEST"
referencing OLD ROW AS "OLD" NEW ROW AS "NEW"
for each row
where (NEW.ID is NULL)
begin
  select USER1.SEQ_TEST.Nextval into :NEW.ID from dual;
end;

用insert语句插入不带主键ID的数据，发现没使用序列的start with，是否触发器语法不对？
