有没有办法在满足某个值的情况下将一行打断？

Question

例如，假设有这样一个 table：

ID        Food
--        ----
1         Fruit

所以每当它说水果时，我想把它分成 3 行：

ID       Food
--       ----
1        Apple
1        Banana
1        Orange

有什么建议吗？

Answer 1

嗯。 . .你可以这样做：

select t.id, coalesce(a.alt, t.food) as food
from t outer apply
     (select alt
      from (values ('Apple'), ('Banana'), ('Orange')) v(alt)
      where t.food = 'Fruit'
     ) a;

Answer 2

select ID, Food FROM YourTable WHERE food <> 'Fruit' 
UNION 
select ID, f2 FROM YourTable JOIN 
    (SELECT'Apple' f2 
        union 
        SELECT 'Banana' f2 
        UNION 
        SELECT 'ORANGE' f2
    ) DT 
        ON food = 'Fruit'

Is there a way to break out a row if it meets a certain value?
