    HAVING SUM(db.prod.cycles) >= 0.5
    ORDER BY DATE_FORMAT(db.prod.start_date, "%m") ASC, DATE_FORMAT(db.prod.start_date, "%d") ASC;

产生以下错误：

Unknown column 'Unknown column 'db.prod.start_date' in 'order clause'

使用 Sequel Pro。

我的目标是复制符合以下条件的每一列：

SUM(db.prod.cycles) >= 0.5

整个查询将在给我错误之前完成（这么大的查询需要一分钟左右）。

我尝试创建一个子查询并使用UNION 而不是UNION ALL 来解决问题，但没有成功。

【参考方案1】：

在 UNION 中的两个查询之后，字段“db.prod.start_date”现在称为“START DATE (TEST)”。尝试更改您的 ORDER BY 子句以引用新的“作为列名”。

示例：ORDER BY START DATE (TEST)

【讨论】：

查询有效，但现在两个表都是ORDER BY 不是在一个完整的表中，而是在两个表中，一个在另一个之后。例如，我想让我的报告的第一个条目翻倍。它确实翻了一番，但第二行可以在UNION ALL 中第一个表的最后一行之后找到。我该如何解决这个问题？

一种快速而肮脏的方法是在两个查询中添加一列并首先按该列排序，然后按其余列排序。第一个查询中的列可能类似于“1 as QueryNumber”。在第二个查询“2 as QueryNumber”中。按查询编号等排序...

又工作了！我只是使用sort 作为列标题，但它有效！非常感谢！
