mysql使in、find_in_set按顺序查出来

select * from table_name where id in ()或者select * from table_name where find_in_set()的时候，MySQL会自动按主键自增排序，要是按给定的顺序来取，如何实现呢？

1、使in按顺序查出来select ID from IndexData where Type=2 and RelateID in(2,4,1,3) order by FIND_IN_SET(RelateID,'2,4,1,3');

2、使find_in_set按顺序查出来select ID from IndexData where Type=2 and FIND_IN_SET(RelateID,'2,4,1,3') order by FIND_IN_SET(RelateID,'2,4,1,3');

find_in_set实现 1,2,3   查询  3,6,11(departure字段)

(FIND_IN_SET(1,departure) or FIND_IN_SET(2,departure) or FIND_IN_SET(3,departure)
