Question

有没有办法在MySQL中通过Word订购？

例如：

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

我想按顺序获取行列表：Business，Professional，然后是Consumer而不是字母顺序。

Answer 1

试试这个：

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

UNION

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

UNION

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