Question

因此，我尝试在查询中添加新行，但不幸的是我遇到了此错误：

SQLSTATE [42000]：语法错误或访问冲突：1064您有一个您的SQL语法错误；检查与您的手册相对应的手册 MariaDB服务器版本可在'FROM附近使用正确的语法职业解决方案

我要添加的内容：

career_solutions_certification as certification,

INNER JOIN certification
ON career_solutions_certification.id = career_solutions.certification

 $career_solution->topic_certification_id = $request['topic_certification_id'];$career_solution->save();

这是我的代码

$career_solutions_data = DB::select(" 
SELECT 
career_solutions.id,
career_solutions.user_id,  
career_solutions.subject, 
career_solutions.date, 
career_solutions.public, 
career_solutions.views, 
career_solutions.optional, 
career_solutions.on_offer, 
users.username, 
users.profile_picture, 
categories.category, 
categories.category_url, 
categories.color, 
career_solutions_categories.category as sub_category,
career_solutions_format.category as event_format,
career_solutions_certification.category as certification,

FROM career_solutions 

INNER JOIN categories 
ON categories.id = career_solutions.topic_category_id 

INNER JOIN career_solutions_format
ON career_solutions_format.id = career_solutions.topic_format_id

INNER JOIN certification
ON career_solutions_certification.id = career_solutions.certification

INNER JOIN career_solutions_categories 
ON career_solutions_categories.id = career_solutions.topic_subcategory_id 

INNER JOIN users 
ON users.id = career_solutions.user_id 


INNER JOIN privacy_settings 
ON privacy_settings.user_id = users.id 

WHERE users.deleted_at IS NULL 
AND ( 
(privacy_settings.career_solutions = 0 AND public = 1 ) 
OR (users.id IN ( 

SELECT contacts.contact_id 
FROM contacts 
WHERE contacts.user_id = $id 
) 
) 
) 

OR users.id = $id 

ORDER BY date desc limit 5000 
");

我的表格是career_solutions_certification /列id和category。
