带有 AND 运算符的简单 SQL 语法 NOT LIKE 似乎被忽略了

Question

非常感谢您的帮助！我似乎在这里没有做任何事情。我想要做的是删除特定列中具有特定值的行。像这样：

Where SegStart_Date between getdate()-90 and getdate()-1
    And q.Center not like 'Collections Center'
    And q.Center not like 'Cable Store'
    And q.Center not like 'Business Services Center'
    And q.Center not like 'Escalations'

然而，我所有的尝试都是徒劳的，因为查询无论如何都会返回带有它们的行。我在这里做错了什么？

整个查询如下：

Select segstart,
CASE
--when hour is = 0 and min < 30 then 0
WHEN DATEPART(HOUR, segstart) = 0 AND DATEPART(MINUTE, segstart) < 30 THEN CAST('0' as int)
--when hour is = 0 and min > 30 then 30
WHEN DATEPART(HOUR, segstart) = 0 AND DATEPART(MINUTE, segstart) >= 30 THEN CAST('30' as int)
--when hour is 1 and min < 30 then 100
WHEN DATEPART(HOUR, segstart) = 1 AND DATEPART(MINUTE, segstart) < 30 THEN CAST('100' as int)

Answer 1

在底部有一个OR，我认为即使它们具有排除值，它们也会吸进一些行。没有括号的效果是(A AND B AND C ... AND Z) OR W。也许您需要对谓词进行不同的分组。

虽然我们在这里，但您在这里不需要LIKE，因为您正在寻找完全匹配的内容。改为这样做：

Where SegStart_Date between getdate()-90 and getdate()-1
    And q.Center not in ('Collections Center',
                         'Cable Store',
                         'Business Services Center',
                         'Escalations')

底部的东西也是如此。

Answer 2

您对 AND 和 OR 之间的优先级感到困惑。

OR 的优先级低于 AND，这使您的查询返回 e.disposition like '4' 的任何行

几周前，我在对Need help with correct SQL 的回答中为一个等效问题写了一个冗长的解释。

Answer 3

你有一个包围问题：

   AND e.transferred like '1'
    OR e.disposition like '4'

应该是这样的

   AND (e.transferred like '1'
    OR e.disposition like '4')

或

   (... 
   AND e.transferred like '1')
    OR e.disposition like '4'

?

Answer 4

正如其他人指出的那样，SQL 中布尔运算符的优先级如下。

• 不是
• 和
• 或者

这解释了您遇到的问题。

我在您发布的代码中注意到的另一件事是它包含类似的行

WHEN DATEPART(HOUR, segstart) = 0 
      AND DATEPART(MINUTE, segstart) < 30 THEN CAST('0' as int)

这可以/应该写成没有从 string 到 int 的强制转换为

WHEN DATEPART(HOUR, segstart) = 0 AND DATEPART(MINUTE, segstart) < 30 THEN 0

但实际上我认为你可以去掉整个大写的 case 表达式并将其替换为

100*DATEPART(HOUR, segstart) +30*(DATEPART(MINUTE, segstart)/30)  as Interval
