Question

考虑以下2个表格....

M.no   budget    created date
1      250M       2010
2      210M       2011
3      200M       1999
4      150M       1994

S.no   Name     
1      Avator
2      Transformers
3      Titanic
4      Dark knight

现在我想要一个查询来查找 预算大于 的电影名称。

Answer 1

select m.name 
from movies m inner join budgets b on (b.no = m.no)
where b.budget > (select budget 
                  from from movies mm inner join budgets bb on (bb.no = mn.no) 
                  where mm.name = ?)

Answer 2

所有电影名称及其预算：

SELECT S.name, M.budget
FROM   S
JOIN   M ON M.no = S.no

泰坦尼克号的预算：

SELECT M.budget
FROM   S
WHERE  S.Name = 'Titanic'
JOIN   M ON M.no = S.no

预算超过泰坦尼克号的所有电影名称：

SELECT S.name
FROM   S
WHERE  M.budget > (
    SELECT M.budget
    FROM   S
    WHERE  S.Name = 'Titanic'
    JOIN   M ON M.no = S.no
)
JOIN   M ON M.no = S.no

需要MYSQL查询此方案
