mysql - 无明显原因的错误 1064

Question

我收到这个查询:

SELECT  companies_comments.id as id, 
        companies_comments.post as post, 
        companies_comments.comment as comment, 
        companies_comments.date as date, 
        companies.`id` AS company, 
        companies.`name` as name, 
        companies.`username` as username, 
        companies.`photo` as photo, 
        companies.`status` AS company_status
LEFT JOIN companies ON companies.id = companies_comments.company
WHERE company_status NOT IN (3,4)
AND companies_comments.post =1

错误:错误代码:1064。您的 SQL 语法有错误；检查与您的 MySQL 服务器版本相对应的手册，了解在第 10 行的“LEFT JOIN Companies ON Companies.id = Companies_comments.company WHERE compa”附近使用的正确语法

意外错误 1064。刚刚尝试不使用 ` ，结果相同。没有缺失的列。会发生什么？

Answer 1

您缺少表名以及查询中的 FROM 部分

SELECT  companies_comments.id as id, 
        companies_comments.post as post, 
        companies_comments.comment as comment, 
        companies_comments.date as date, 
        companies.`id` AS company, 
        companies.`name` as name, 
        companies.`username` as username, 
        companies.`photo` as photo, 
        companies.`status` AS company_status
FROM companies, companies_comments
LEFT JOIN companies ON companies.id = companies_comments.company
WHERE companies.company_status NOT IN (3,4)
AND companies_comments.post =1
