MySQLで（）とLIKE一緒

Question

私はより良い方法でこのクエリ

SELECT * FROM [table] WHERE 
(column1 = 'dog' AND column2 = 1) OR 
(column1 = 'cat' AND column2 = 2) OR 
(column1 = 'mouse' AND column3 = 3) OR 
(column1 = 'wolf' AND column4 = 4); 

を書き換えることができることを知っている：

SELECT * FROM [table] WHERE 
(column1 = 'dog' AND column2 like '%red%') OR 
(column1 = 'cat' AND column2 like '%blue%') OR 
(column1 = 'mouse' AND like '%red%') OR 
(column1 = 'wolf' AND column2 like '%green%'); 

：このクエリの同様の方法が

SELECT * 
FROM [table] 
WHERE (column1, column2) IN (('dog', 1), ('cat', 2), ('mouse', 3), 
('wolf', 4)); 

あり

Answer 1

いいえ。タプルリスト形式

(a,b) IN ((2,3) , (5,7) , (11,13)) 

は、等価比較のためにのみ使用されます。

しかし、クエリを書くには他にもいくつかの方法があります。

SELECT t1.* FROM mytable t1 WHERE t1.column1 = 'dog' AND t1.column2 LIKE '%red%' 
UNION ALL 
SELECT t2.* FROM mytable t2 WHERE t2.column1 = 'cat' AND t2.column2 LIKE '%blue%' 
UNION ALL 
SELECT t3.* FROM mytable t3 WHERE t3.column1 = 'mouse' AND t3.column2 LIKE '%red%' 
UNION ALL 
SELECT t4.* FROM mytable t4 WHERE t4.column1 = 'wolf' AND t4.column2 LIKE '%green%'
