MySQL多个where条件，结果不满足所有条件

Question

我有一个从 expressJS 注入 MySQL 的查询，但是当这些查询被执行时。有时我返回的数据不正确满足条件。

---

原文：

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

结果显示任何状态的项目正在被拉取，但满足日期条件。

试过了：

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 ordereddate 或 duedate 超出日期范围，则该项目将被排除在结果之外。

改为AND而不是OR

试过了：

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

结果： 正确返回所有内容，除非 ordereddate 或 duedate 超出日期范围，否则该行将被排除在结果之外。

结合ordereddate 和duedate where 条件

试过了：

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

这个似乎提取了正确的状态，但是日期不正确，它似乎提取了状态为 Invoiced 的任何内容，并且忽略了日期范围。

如果我正确理解您的问题，您需要使用额外的括号：

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')
    )
;
