表结构如下: 
mysql> select * from test; 
+----+-------+ 
| 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 
请问在这样的SQL在Mysql中怎么写? 
网上查到sqlserver中可以用order by charindex解决,但是没看到Mysql怎么解决??请高手帮忙,谢 
谢! 
select * from a order by substring_index('3,1,2',id,1); 
试下这个good,ls正解。 
order by find_in_set(id,'3,1,5') 
谢谢,经测试order by substring_index和order by find_in_set都可以														
													
					Mysql select in 按id排序实现方法
								表结构如下:mysql>select*fromtest;+----+-------+|id|name|+----+-------+|1|test1||2|test2||3|test3||4|test4||5|tes
