订购没有标识符的MySQL结果？

要订购没有标识符的MySQL结果，语法如下-

select * from yourTableName order by 1 DESC LIMIT yourLimitValue;

让我们首先创建一个表-

mysql> create table DemoTable1325
   -> (
   -> Id int,
   -> Name varchar(20)
   -> );

使用插入命令在表中插入一些记录-

mysql> insert into DemoTable1325 values(100,'Chris');
mysql> insert into DemoTable1325 values(101,'Bob');
mysql> insert into DemoTable1325 values(120,'David');
mysql> insert into DemoTable1325 values(115,'Sam');
mysql> insert into DemoTable1325 values(130,'Carol');
mysql> insert into DemoTable1325 values(150,'Mike');

使用select语句显示表中的所有记录-

mysql> select * from DemoTable1325;

这将产生以下输出-

+------+-------+
|  Id  | Name  |
+------+-------+
|  100 | Chris |
|  101 | Bob   |
|  120 | David |
|  115 | Sam   |
|  130 | Carol |
|  150 | Mike  |
+------+-------+
6 rows in set (0.00 sec)

这是查询不带标识符的MySQL结果的查询-

mysql> select * from DemoTable1325 order by 1 DESC LIMIT 4;

这将产生以下输出

+------+-------+
| Id   | Name  |
+------+-------+
| 150  | Mike  |
| 130  | Carol |
| 120  | David |
| 115  | Sam   |
+------+-------+
4 rows in set (0.00 sec)
