SQL NOT EXISTS 子查询未按预期运行

【中文标题】SQL NOT EXISTS 子查询未按预期运行【英文标题】：SQL NOT EXISTS sub query not functioning as expected 【发布时间】：2018-11-14 01:49:50 【问题描述】：

我有一个问题，我使用查询根据文章的前置时间过滤我的结果。对我来说令人困惑的部分是其中的一个子部分，我需要根据交货时间和原产国过滤某些文章。我试图在WHERE 旁边使用NOT EXISTSstatement 来做到这一点，但结果似乎不是我所期望的。例如，所有原产国为洪都拉斯且交货时间为 90 的文章不应返回 so_conf_del_date 为 2/15/19 之后的任何结果......但是在结果中，我得到了许多日期的结果，这些结果应该是 3 月被排除在我能看到的范围之外。以为我会对它有不同的看法，因为我真的不使用不存在大量。谢谢。

更新：从 NOT EXISTS 更改为 NOT IN 并更新了相关性。另请注意，子查询完全按照它应该执行的方式执行，因此不确定为什么我得到的结果超出范围

查询已更新：

/* What to do about multiple COO's in ONE RANGE? ...join on order ORDER_ITEM.SEASONAL_INDICATOR? */
/* Use CASE WHEN in subquery to JOIN outerquery on vw_order_item.seasonal_indicator = OneRange_NAM.SEASON */
/* Assumption is being made that 'seasonal indicator' in vw_order_item would align with 'season' and thus COO in OneRange */
/* Added Date/LeadTime Parameters */
/* Use 'Planned Delivery Time'...this includes lead time and delivery time? */
/* Right join to ONE RANGE */
/* ARUN has no fully unallocated quantities - YES IT DOES */
/* 11/12/18 - replaced RDD with CDD */

【问题讨论】：

猜一猜......你需要更多的括号来正确定义OR布尔表达式。你有一个OR（或者可能很多），它使整个布尔表达式短路。似乎很奇怪，因为在所有其他行上执行相同操作的外部语句工作完美......想知道它是否与 IN 语句有关，或者它如何连接到外部查询？ 【参考方案1】：

您的 OR 短路。比如看这块：

SELECT *
FROM Table
WHERE  aa1.LeadTime = '30'
AND    o1.country_of_origin IN ('EL SALVADOR','HONDURAS','MEXICO','U S A' ,'GUATEMALA')
AND    a1.so_conf_del_date > '12/15/2018'
OR     aa1.LeadTime = '45'

返回所有带有aa1.LeadTime = '45' 的记录，无论其他条件如何。

我猜你的意思是：

WHERE  
(
aa1.LeadTime = '30'
AND    o1.country_of_origin IN ('EL SALVADOR','HONDURAS','MEXICO','U S A' ,'GUATEMALA')
AND    a1.so_conf_del_date > '12/15/2018'
)
OR     
(
aa1.LeadTime = '45' 
AND    o1.country_of_origin IN ('EL SALVADOR','HONDURAS','MEXICO','U S A' ,'GUATEMALA')
AND    a1.so_conf_del_date > '01/01/2019'
)
OR     
(
aa1.LeadTime = '60' 
AND    o1.country_of_origin IN ('EL SALVADOR','HONDURAS','MEXICO','U S A' ,'GUATEMALA')
AND    a1.so_conf_del_date > '01/15/2019'
)
....
....

这是一个非常不同的表达方式。

【讨论】：

啊，感谢您的澄清！出于某种原因，我假设执行顺序在每个 OR 处重新开始，我将试一试！仍在返回范围之外的结果 - 例如，提前期 45 表示返回日期早于 2019 年 1 月 1 日...将继续挖掘。谢谢。您的观点绝对正确 - 为了停止让结果超出我的范围，我将 NOT IN 移到 q0 上的 JOIN 内，这似乎解决了问题。试图完全理解为什么。上面贴出最终代码。
