有人能解释一下，当明确提到日期条件大于2014时，为什么查询返回所有表值？我理解将消息条件保留在括号中会产生适当的结果。但是，我想知道为什么sql排除了前面提到的日期条件，而not like运算符不在括号中。

您缺少了偏执so或优先级较低的转换为

WHERE 
MESSAGE NOT LIKE '%"FOOT_BALL"%' OR (MESSAGE NOT LIKE '%BASKET_BALL%'
AND CREATED_ON >= '2014-01-01')

MESSAGE NOT LIKE '%"FOOT_BALL"%' 

返回3行，不关心日期

将两个OR都放在括号中。

这是因为

和

运算符的值大于

或

。更改为：

SELECT 
    ID,CREATED_ON,MESSAGE 
FROM 
    MESSAGE
WHERE 
    (MESSAGE NOT LIKE '%"FOOT_BALL"%' OR MESSAGE NOT LIKE '%BASKET_BALL%')
    AND CREATED_ON >= '2014-01-01'

根据您的需要，括号应该围绕后面的部分，如下所示：

    MESSAGE NOT LIKE '%"FOOT_BALL"%' OR (MESSAGE NOT LIKE '%BASKET_BALL%'
    AND CREATED_ON >= '2014-01-01')

同样不带支架，也包括带脚球和带篮球的线条，如篮球！=足球——关于或的逻辑用法的问题。。。您可能正在为您的评论jpw寻找某种xor运算符库…我理解，通过放置括号，我们可以得到正确的结果。但我想理解sql执行此条件消息的顺序，它不像“%”FOOT\u BALL“%”，或者它不像“%BASKET\u BALL%”，并且在“>=”2014-01-01”上创建，因为查询会一起忽略日期条件。@RameshM它不会忽略日期，但日期和BASKET\u BALL条件是绑定在一起的；它与不喜欢足球的第一排、篮球和日期的第二排、不喜欢足球的第三排和第四排相匹配。
