數據庫中的選擇語句錯誤

Question

我有一個 SELECT 語句，但它在 MYSQL 中給了我一個錯誤。 不知道我做錯了什么。

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

嘗試這個 ：

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

注意' （單引號）
