Question

如果我在当前表中执行搜索查询，就没有问题：

SELECT * FROM articles 
WHERE CONCAT(title, content, author) LIKE '%searchstring%'

但是，如果我想包括联接表中的列，则无法将该列添加到where子句中：

    SELECT articles.*, associations.name AS association_name 
FROM articles 
    JOIN associations 
    ON articles.association_id = associations.id
    WHERE CONCAT(title, content, author,association_name ) 
LIKE '%searchstring%'

错误变为"Unknown column 'association_name' in where clause"

那我如何在搜索查询中包括该列？

只需写下注释中上面提供的答案即可。您应该这样做：

SELECT articles.*, associations.name AS association_name 
FROM articles 
JOIN associations ON articles.association_id = associations.id
WHERE CONCAT(title, content, author, associations.name) 
  LIKE '%searchstring%'
