【问题描述】：

我正在尝试从 sql 连接查询中获取数据。当我在 where 子句中使用具有 3 个组合的日期过滤器时，查询不起作用。

                                SELECT * FROM #tempAllocStatus1 WHERE [All Total] = 0

我在下面的查询行中遇到了问题。

                             AND TPRAssigned.crtddate >= '2017-04-01'  and TPRAssigned.crtddate<= '2017-05-30'

                                      OR TPRReviewer.crtddate >= '2017-04-01'  AND TPRReviewer.crtddate<='2017-05-30'

                                      OR TPRSignoff.crtddate >= '2017-04-01'  AND TPRSignoff.crtddate<='2017-05-30'

如果我使用任意 2 个日期组合，它工作正常。如果我添加日期的第三个条件，它会加载很长时间并且没有得到任何数据。请帮忙。

【问题讨论】：

我建议您另外问一个关于“如何简化此查询”的问题？所有这些相关的子查询将花费您大量的资源，并且可以用简单的连接和案例语句代替。
请在代码问题中给出minimal reproducible example--剪切&粘贴&运行代码；具有期望和实际输出（包括逐字错误消息）的示例输入（作为初始化代码）；标签和版本；明确的规范和解释。这包括您可以提供的最少代码，即您显示的代码可以通过您显示的代码扩展为不正常。（调试基础。）对于包含 DBMS/产品和 DDL 的 SQL，其中包括约束和索引以及表格格式的基表初始化。对于包括 EXPLAIN 结果和统计信息的 SQL 性能。 PS 显然有非最小代码。
了解 LEFT JOIN ON 返回的内容：INNER JOIN ON 行 UNION ALL 不匹配的左表行，由 NULL 扩展。作为 OUTER JOIN 的一部分，始终知道您想要什么 INNER JOIN。 WHERE 或 INNER JOIN ON 在 OUTER JOIN ON 删除任何由 NULL 扩展的行后，需要右 [sic] 表列不为 NULL，即只留下 INNER JOIN ON 行，即“将 OUTER JOIN 转换为 INNER JOIN”。你有那个。 PS“不工作”告诉我们什么。 PS 既然你有一个有用的答案，请提出一个新问题。使用minimal reproducible example。 PS 速度与代码错误无关。

【解决方案1】：

您有操作顺序问题，因为AND 的优先级高于 OR。使用括号强加你想要的逻辑：

WHERE
    ... AND
    (TPRAssigned.crtddate BETWEEN '2017-04-01' AND '2017-05-30') OR
    (TPRReviewer.crtddate BETWEEN '2017-04-01' AND '2017-05-30') OR
    (TPRSignoff.crtddate BETWEEN '2017-04-01' AND '2017-05-30')

请注意，您当前的逻辑实际上被评估为：

(TPRAssigned.crtddate >= '2017-04-01' AND TPRAssigned.crtddate <= '2017-05-30') OR
(TPRReviewer.crtddate >= '2017-04-01' AND TPRReviewer.crtddate <= '2017-05-30') OR
(TPRSignoff.crtddate >= '2017-04-01'  AND TPRSignoff.crtddate <= '2017-05-30')

很可能，这不是您想要的逻辑。

【讨论】：

我也试过这些方法。但它也加载了很长时间并且超时
@user3581029 您的查询性能是另一个主题，而不是您所问的。我修正了你的逻辑。
我已经尝试过这些带括号的方法。无论有没有括号，这两种组合都有效。即使使用括号，第三个 OR 条件也不起作用。正如我在查询中提到的，它加载了很长时间并且没有得到任何数据
您的查询量很大，我不适合提出优化建议。
谢谢蒂姆。其他任何人都可以帮我解决这个问题。
