ORA-01403:no data found 解决方法两则
解决方法一:加一个exception异常处理
exception when no_data_found then
….
解决方法二:更改select语句,如:
select count(*) field into var from table where ….
增加一个count(*)即使没有找到数据,也会返回0,而不是null。
请问:在执行以下语句时报错。
declare
v_spec varchar2(255);
begin
for r in (select subne.id, subne.subneassetid from subne where subne.subneassetid >0)
loop
select subnetype.subnemodel into v_spec from subnetype , subne
where subne.id = r.id and subne.subnetypeid = subnetype.id;
update asset set specformula = v_spec where id = r.subneassetid and specformula is null;
 oracle账号; end loop;
end;
ORA-01403: 未找到数据
ORA-06512: 在line 6
加个独立的块,
begin
select subnetype.subnemodel into v_spec from subnetype , subne
where subne.id = r.id and subne.subnetypeid = subnetype.id;
update asset set specformula = v_spec where id = r.subneassetid and specformula is null;
exception
when no_data_found then
null;
end;
这样在no_data_found时,循环就不会跳出了!
