表結構如下:
mysql> select * from test;
+----+-------+
| id | name |
+----+-------+
| 1 | test1 |
| 2 | test2 |
| 3 | test3 |
| 4 | test4 |
| 5 | test5 |
+----+-------+
執(zhí)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)
這個select在mysql中得結果會自動按照id升序排列,
但是我想執(zhí)行"select * from test where id in(3,1,5);"的結果按照in中得條件排序,即:3,1,5,
想得到的結果如下:
id name
3 test3
1 test1
5 test5
請問在這樣的SQL在Mysql中怎么寫?
網(wǎng)上查到sqlserver中可以用order by charindex解決,但是沒看到Mysql怎么解決??請高手幫忙,謝
謝!
select * from a order by substring_index('3,1,2',id,1);
試下這個good,ls正解。
order by find_in_set(id,'3,1,5')
謝謝,經(jīng)測試order by substring_index和order by find_in_set都可以
