+----+-------+
| id | name  |
+----+-------+
|  1 | test1 |
|  2 | test2 |
|  3 | test3 |
|  4 | test4 |
|  5 | test5 |
+----+-------+

执行以下SQL:
mysql> select * from test where id in(3,1,5);
+----+-------+
| id | name  |
+----+-------+
|  1 | test1 |
|  3 | test3 |
|  5 | test5 |
+----+-------+
3 rows in set (0.00 sec)

这个select在mysql中得结果会自动按照id升序排列,
但是我想执行"select * from test where id in(3,1,5);"的结果按照in中得条件排序,即:3,1,5,想得到的结果如下:
id   name
3    test3
1    test1
5    test5



mysql> select * from Tbl_FQQ_FScoreCount where id in(3,1,5) order by find_in_set(id,'3,1,5');    
+----+-----------+-------------+
| ID | FQQ       | FScoreCount |
+----+-----------+-------------+
|  3 | 715113297 |          40 |
|  1 |  78540474 |          37 |
|  5 |   1735548 |           0 |
+----+-----------+-------------+



select id, name from table where 'daodao' IN (list);
IN (list);      如果list是常量，则可以直接用IN，大家怎么看？
