mysql - mysql语法不等于多个值

Question

我正在尝试为以下情况获取正确的语法？

SELECT * 
FROM wp_posts AS p 
WHERE post_type = 'post' 
AND post_status = 'publish' 
AND ID <> 5616,1095,1357,271,2784,902
ORDER BY post_title DESC

Answer 1

而不是<>，您可以使用NOT IN (5616,1095...)

SELECT * 
FROM wp_posts AS p 
WHERE post_type = 'post' 
AND post_status = 'publish'
AND ID NOT IN (5616,1095,1357,271,2784,902)
ORDER BY post_title DESC 

Answer 2

运算符比较<>单个左右参数以查看它们是否不相等。在您的情况下，您需要检查一个左手参数（我假设）以查看ID右侧是否没有值。因此你应该使用ID NOT IN (5616,1095,1357,271,2784,902)

Answer 3

SELECT * FROM wp_posts AS p WHERE post_type = 'post' 
AND post_status = 'publish' AND 
ID NOT IN (5616,1095,1357,271,2784,902) ORDER BY post_title DESC
