SELECT * FROM tbl WHERE clm LIKE CONCAT('%',,'%') - HOW?

Question

How can I combine those two queries into one?

1) This finds the japanese sign for dog (犬):

SELECT japanese 
  FROM edict 
 WHERE english LIKE \'dog         


        

Answer 1

Parenthesises are important, therefore, try this :

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

It might have been good to tell us what error you received, though.

Answer 2

Use:

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

I don't recommend the use of LIMIT, but if you really need it for this, use:

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
