MySQL查询获取多个最小值？
为此，您可以将子查询与一起使用MIN()。让我们首先创建一个表-
mysql> create table DemoTable-> (
-> Name varchar(20),
-> Score int
-> );
使用插入命令在表中插入一些记录-
mysql> insert into DemoTable values('John',56);mysql> insert into DemoTable values('John',45);
mysql> insert into DemoTable values('John',58);
mysql> insert into DemoTable values('Chris',43);
mysql> insert into DemoTable values('Chris',38);
mysql> insert into DemoTable values('Chris',87);
使用select语句显示表中的所有记录-
mysql> select *from DemoTable;
+-------+-------+| Name | Score |
+-------+-------+
| John | 56 |
| John | 45 |
| John | 58 |
| Chris | 43 |
| Chris | 38 |
| Chris | 87 |
+-------+-------+
6 rows in set (0.00 sec)
这是获取多个最小值的查询-
mysql> select *from DemoTable tbl1-> where Score IN( select min(Score) from DemoTable tbl2 where tbl1.Name=tbl2.Name);
+-------+-------+| Name | Score |
+-------+-------+
| John | 45 |
| Chris | 38 |
+-------+-------+
2 rows in set (0.00 sec)
