Oracle SQL Sum缺少右括號

Question

我有一個適用於MySQL的Oracle SQL，但在Oracle上運行時，我得到了「缺少的右括號」。

Answer 1

Oracle沒有使用CASE或者像MySQL的簡寫方式。因此，你將不得不使用一個CASE內您sum：

select p.id, p.name, 
    t.id as toyid, 
    t.name as toyname 
from person p 
inner join toys t on p.id = t.person_id 
inner join 
(
    select person_id 
    from toys 
    group by person_id 
    having sum(case when name = 'hat' then 1 else 0 end) > 0 and 
    sum(case when name = 'doll' then 1 else 0 end) > 0 
) t2 
    on p.id = t2.person_id;
