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)
