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。

原始

：

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均被拉出，但满足日期条件。

尝试过：

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不在日期范围内，则该项目将不在结果之列。

更改为AND，而不是OR

尝试过：

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，否则该行将不包含在结果中。

结合ordereddate和duedate的条件

尝试过：

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”的任何东西，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')
    )
;

MySQL多重条件，结果不满足所有条件
