mysql order by field自定义排序

语法

ORDER BY FIELD(`id`, 5, 3, 7, 1)

要注意的是, FIELD 后面是没有空格的.

因此, 完整的 SQL 为:

SELECT * FROM `MyTable` 
WHERE `id` IN (1, 7, 3, 5) 
ORDER BY FIELD(`id`, 5, 3, 7, 1)

 

常见应用

SELECT * FROM `MyTable` 
WHERE `name` IN ('张三', '李四', '王五', '孙六') 
ORDER BY FIELD(`name`, '李四', '孙六', '张三', '王五')

另外除了使用field，还可以用locate和instr函数进行排序：

SELECT * FROM mr_member ORDER BY locate(id,'5056,5052,5054,5050') desc;
SELECT * FROM mr_member ORDER BY field(id,5056,5052,5054,5050) desc;
SELECT * FROM mr_member ORDER BY INSTR('5056,5052,5054,5050',id) desc;
