您可以重写您的问题吗？对许多“请帮助我在这里我尝试”。 – Mualig

你只需要做一个子查询：

SELECT ... dtStrt ... 
FROM (
    (SELECT ... as dtStrt, ... 
    FROM ... JOIN... WHERE...) 
    union all 
    (SELECT ... as dtStrt, ... 
    FROM ... JOIN... WHERE...) 
) as val 
ORDER BY dtStrt

其实，你不会 - 在UNION中的ORDER BY是违反最终结果集的。 MySQL在UNION'd语句中以per语句为基础支持ORDER BY，但只有当查询被括号/括号包围时 –
