SELECT * FROM表WHERE列LIKE CONCAT（'％'，<other sql =“”query =“”limit =“”1 =“”>，'％'） - 如何？</other>

Question

如何将这两个查询合并为一个？

1）这找到狗的日本标志（犬）：

SELECT japanese 
  FROM edict 
 WHERE english LIKE 'dog' 
 LIMIT 1;

2）这会找到所有带有“狗”（犬）标志的日语单词：

SELECT japanese 
  FROM edict 
 WHERE japanese LIKE '%犬%';

---

3）我将这两者合二为一，因为这不起作用？！

SELECT japanese 
FROM edict 
WHERE japanese
LIKE CONCAT('%',
    SELECT japanese FROM edict WHERE english LIKE 'dog' LIMIT 1,'%'
);

Answer 1

括号内容很重要，因此，请尝试以下方法：

SELECT japanese
FROM edict
WHERE japanese LIKE CONCAT('%', 
                           (SELECT japanese FROM edict WHERE english LIKE 'dog' LIMIT 1), 
                           '%');

但是，告诉我们你收到的错误可能会很好。

Answer 2

使用：

SELECT a.japanese 
  FROM EDICT a
  JOIN EDICT b ON b.japanese = a.japanese
 WHERE b.english LIKE 'dog'

我不建议使用LIMIT，但如果您真的需要它，请使用：

SELECT a.japanese 
  FROM EDICT a
  JOIN (SELECT t.japanese
          FROM EDICT t
         WHERE t.english LIKE 'dog'
         LIMIT 1) b ON b.japanese = a.japanese
