選擇 - 順序在MySQL中的單詞？

Question

有沒有辦法在MySQL中通過Word進行排序？

例如：

SELECT * FROM `table` WHERE `batch` = 'something' AND outcome in ('Business','Professional', 'Consumer') 

我想爲了行的列表：商務，專業，然後消費，而不是字母順序。

Answer 1

試試這個：

SELECT * 
FROM `table` 
WHERE `batch` = 'something' 
     AND outcome in ('Business','Professional', 'Consumer') 
ORDER BY 
    CASE WHEN outcome = 'Business'  THEN 1 
     WHEN outcome = 'Professional' THEN 2 
     WHEN outcome = 'Consumer'  THEN 3 
     ELSE 4 
    END 

Answer 2

你可以結合每一個具體..試試這個。

SELECT * FROM `table` WHERE `batch` = 'something' AND outcome = 'Business' 

UNION 

SELECT * FROM `table` WHERE `batch` = 'something' AND outcome = 'Professional' 

UNION 

SELECT * FROM `table` WHERE `batch` = 'something' AND outcome = 'Consumer'
