mysql - 内部加入 like 子句

Question

我正在使用带有 like 子句的内部连接 ​​..

我试过的sql是

SELECT tbl_songs.id    AS sid, 
       tbl_songs.name  AS sname, 
       tbl_albums.id   AS aid, 
       tbl_albums.name AS aname 
FROM   tbl_songs 
       INNER JOIN tbl_albums 
               ON tbl_songs.albums LIKE '%' + tbl_albums.name + '%'; 

它向我显示语法错误。

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 '+ tbl_albums.name + '%'' at line 2

请详细说明语法错误的原因。

Answer 1

你必须使用 concat ... 形成子句

...LIKE CONCAT('%',tbl_albums.name, '%');

mysql中没有这样的+操作符
