MySQL获取记录按顺序传递给IN条件

Question

希望结果与传递给IN条件的顺序相同：

SELECT * FROM `table_x` WHERE `id` IN (30, 12, 1001, 24);

获得：

id    | field_a | field_b
--------------------------
12    | ...     | ...
24    | ...     | ...
30    | ...     | ...
1001  | ...     | ...

期待：

id    | field_a | field_b
--------------------------
30    | ...     | ...
12    | ...     | ...
1001  | ...     | ...
24    | ...     | ...
