                问题描述

                限时送ChatGPT账号..

                这可能是一个简单的...我怎样才能通过这个查询实现我想要的:

                从没有 id 的帖子中删除(SELECT id FROM posts order by timestamp desc limit 0, 15)

                所以,简而言之,我想删除所有不在最新 15 条上的帖子.

                当我尝试那个查询时,我明白了

                <块引用>

                MySQL 尚不支持 'LIMIT &IN/ALL/ANY/SOME 子查询

                编辑

                mySQL Server 版本:5.5.8mySQL 客户端版本:mysqlnd 5.0.7-dev - 091210 - $Revision: 304625 $

                <块引用>

                错误:#1235 - 此版本的 MySQL 尚不支持 'LIMIT &IN/ALL/ANY/SOME 子查询'

                解决方案

                试试这个:

                删除发件人WHERE id 不在 (选择 * 从 (选择 ID发件人ORDER BY timestamp desc limit 0, 15)作为 t);

                This is probably an easy one... how can I achieve what i want with this query:

                delete from posts where id not in
                (SELECT id FROM posts order by timestamp desc limit 0, 15)
                

                so, to put it in a nutshell, I want to delete every post that isn't on the latest 15.

                When I try that query, I get that

                MySQL doesn't yet support 'LIMIT & IN/ALL/ANY/SOME subquery

                EDIT

                mySQL Server version: 5.5.8

                Error: #1235 - This version of MySQL doesn't yet support 'LIMIT & IN/ALL/ANY/SOME subquery'

                解决方案

                Try this:

                DELETE 
                FROM posts 
                WHERE id not in (
                      SELECT * FROM (
                            SELECT id 
                            FROM posts 
                            ORDER BY timestamp desc limit 0, 15
                      ) 
                      as t);
