MySQL多重条件，结果不满足所有条件

Question

我有一个从expressJS注入MySQL的查询，但是当执行这些查询时。 有时我会返回不正确满足条件的数据。

---

原版的：

SELECT * FROM table
  WHERE status = 'Invoiced'
  AND (ordereddate between '2009-12-01' AND '2011-12-30')
  OR (duedate between '2009-12-01' AND '2011-12-30');

结果：

Ordered Date   Due Date      Status
2009-11-18     2009-12-16    Invoiced
2009-11-18     2009-12-14    Cancelled

结果显示具有任何状态的项目都已被拉出，但满足日期条件。

尝试：

SELECT * FROM table
  WHERE (status = 'Invoiced')
  AND (ordereddate between '2009-12-01' AND '2011-12-30')
  AND (duedate between '2009-12-01' AND '2011-12-30');

结果：如果两个ordereddate或duedate超出日期范围，该项目将被排除在外的结果。

更改为AND而不是OR

---

尝试：

SELECT * FROM table
  WHERE status = 'Invoiced'
  AND (ordereddate AND duedate between '2009-12-01' AND '2011-12-30');

结果：正确返回的一切，除非要么ordereddate或duedate超出日期范围，该行将被冷落的结果。

结合ordereddate和duedate WHERE条件

尝试：

SELECT * FROM table
  WHERE status = 'Invoiced'
  AND (ordereddate OR duedate between '2009-12-01' AND '2011-12-30');

结果：

Ordered Date   Due Date      Status
2008-07-07     2008-07-28    Invoiced
2008-07-07     2008-07-25    Invoiced
2008-07-07     2008-07-23    Invoiced

这似乎拉出了正确的状态，但是日期不正确，它似乎在拉出状态为“已开具发票”的任何内容，而忽略了日期范围。

如果我正确理解了您的问题，则需要使用其他括号：

SELECT
    *
FROM
    table
WHERE
    status = 'Invoiced'
    AND (
           (ordereddate between '2009-12-01' AND '2011-12-30')
        OR (duedate between '2009-12-01' AND '2011-12-30')
    )
;
