在数据库中选择语句错误

Question

我有一个SELECT语句，但它给我一个MYSQL错误。不知道我做错了什么。

SELECT input, 
CASE WHEN input LIKE %is this to% THEN 10 
ELSE CASE WHEN input LIKE %this to you% THEN 12 
END END 
AS 'matches' 
FROM tableName 
LIMIT 0 , 30 

Answer 1

试试这个：

SELECT input, 
CASE 
    WHEN input LIKE '%is this to%' THEN 10 
    WHEN input LIKE '%this to you%' THEN 12 
ELSE 0 
END AS 'matches' 
FROM tableName 
LIMIT 0 , 30 

Answer 2

SELECT input 
CASE WHEN input LIKE '%is this to%' THEN 10 
    ELSE 
    CASE WHEN input LIKE '%this to you%' THEN 12 
    END 
END 
AS 'matches' 
FROM tableName 
LIMIT 0 , 30
