查询以在MySQL中找到第N个最大值
让我们首先创建一个表-
mysql> create table DemoTable-> (
-> Value int
-> );
使用插入命令在表中插入一些记录-
mysql> insert into DemoTable values(40);mysql> insert into DemoTable values(60);
mysql> insert into DemoTable values(45);
mysql> insert into DemoTable values(85);
mysql> insert into DemoTable values(78);
使用select语句显示表中的所有记录-
mysql> select * from DemoTable;
+-------+| Value |
+-------+
| 40 |
| 60 |
| 45 |
| 85 |
| 78 |
+-------+
5 rows in set (0.00 sec)
以下是在MySQL中查找第N个最大值的查询-
mysql> select * from DemoTable order by Value desc limit 2,1;
这将产生以下输出-
+-------+| Value |
+-------+
| 60 |
+-------+
1 row in set (0.00 sec)
