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); +----+
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
