测试了很久，网上说的方法很多，其实都是错误的，正确的写法：
declare
cursor rowAll is select * from tb_news where 1=1;
row1 tb_news%rowtype;
i int;
begin
i := 0;
for row1 in rowAll
loop
row1.id := fn_gen_getid('tb_news');
row1.addtime := sysdate;
row1.starttime := sysdate;
row1.adduserid := -100;
insert into tb_news values row1;
commit;
end loop;
end;
误打误撞，乱写一通，没想到这样可以。不过我在查询窗口使用dbms_output.put_line(sysdate); 怎么都报错，崩溃！by default7#zbphp.com
