SQL'LEFT JOIN'两个表，每个表都有'Where'（不是联接条件）

Question

此Left Join查询效果很好：

SELECT * FROM `Articles`  
  LEFT JOIN `uploaders` ON 
   uploaders.username=Articles.Poster
   ORDER BY `DATE` ASC  LIMIT 5;

但是在第一个表中添加“位置”时

 SELECT * FROM `Articles`  WHERE `Content` OR `Title` LIKE '%somthing'
  LEFT JOIN `uploaders` ON 
   uploaders.username=Articles.Poster
   ORDER BY `DATE` ASC  LIMIT 5;

我收到语法错误。 我尝试命名第一个结果，但仍然是相同的错误

1：

SELECT * FROM `Articles`  WHERE `Content` OR `Title` LIKE '%somthing' AS art
  LEFT JOIN `uploaders` ON 
   uploaders.username=art.Poster
   ORDER BY `DATE` ASC  LIMIT 5;

2：

(SELECT * FROM `Articles`  WHERE `Content` OR `Title` LIKE '%somthing')Art
  LEFT JOIN `uploaders` ON 
   uploaders.username=Art.Poster
   ORDER BY `DATE` ASC  LIMIT 5;

我究竟做错了什么？ 如果不是这样，我还能怎么做？

Answer 1

 SELECT * FROM `Articles` 
 LEFT JOIN `uploaders` ON 
   uploaders.username=Articles.Poster
 WHERE `Content` LIKE '%somthing' OR `Title` LIKE '%somthing'
 ORDER BY `DATE` ASC  LIMIT 5;

Answer 2

加入后的位置：

SELECT * FROM `Articles`  
  LEFT JOIN `uploaders` ON 
   uploaders.username=Articles.Poster
WHERE `Content` LIKE '%somthing' OR `Title` LIKE '%somthing'
   ORDER BY `DATE` ASC  LIMIT 5;
