Question

我的查询包含IN和＆amp;查询中NOT，但它给了我一个错误：

错误代码：1064。您的SQL语法有错误;查看与您的MariaDB服务器版本对应的手册，以便在第1行的“IN（'aniket27'）ORDER BY id DESC LIMIT 2'附近使用正确的语法

这是我查询的外观

SELECT * FROM users 
WHERE username IN ('aniket27','deepakrajak','bhawana','Mehul13','sanchayeeta',
                   'shivajidutta', 'anamika_4a','parekh','anupamkumar') 
AND NOT IN ('aniket27') 
ORDER BY id DESC LIMIT 2

Answer 1

您必须指定NOT IN

的列

SELECT * FROM users WHERE username IN ('...') AND username NOT IN ('aniket27') ORDER BY id DESC LIMIT 2

但第一个条件足以匹配NOT IN部分中列出的元素，只需从第一个IN列表中删除它们。

Answer 2

您忘记将字段名称放在“NOT IN”之前：

SELECT * FROM users WHERE username IN ('aniket27','deepakrajak','bhawana','Mehul13','sanchayeeta','shivajidutta','anamika_4a','parekh','anupamkumar') AND username NOT IN ('aniket27') ORDER BY id DESC LIMIT 2

Answer 3

试试这个：

SELECT * FROM users 
WHERE username IN ('aniket27','deepakrajak','bhawana','Mehul13','sanchayeeta','shivajidutta','anamika_4a','parekh','anupamkumar') 
AND username NOT IN ('aniket27') 
ORDER BY id DESC LIMIT 2;

如何使用IN＆amp;不在同一个查询中
