MySQL-在自定义列上创建搜索

我想运行如下的MySQL查询：

 SELECT * FROM `project` WHERE (project.sold_tons + project.recycled_tons + project.recycled_tons + project.donation_tons)*100/project.total_excess_furniture)>90

#1064 - You have an error in your SQL syntax; check the manual that
corresponds to your MySQL server version for the right syntax to use
near ')>90 ORDER BY `is_archived` DESC 
LIMIT 0, 25' at line 1 

当我运行它时，会出现如下错误：

 SELECT * FROM `project` WHERE (project.sold_tons + project.recycled_tons + project.recycled_tons + project.donation_tons)*100/project.total_excess_furniture)>90

#1064 - You have an error in your SQL syntax; check the manual that
corresponds to your MySQL server version for the right syntax to use
near ')>90 ORDER BY `is_archived` DESC 
LIMIT 0, 25' at line 1 

我能做吗？ 或 有没有其他方法可以创建这样的搜索

如果不是，那么Laravel或MySQL中的解决方案是什么

谢谢你的帮助。

你错过了“（”在哪里

试试这个

SELECT * FROM `project` 
WHERE ((project.sold_tons + project.recycled_tons + project.recycled_tons + project.donation_tons) *100/project.total_excess_furniture) > 90
