使用MySQL查询以降序获取固定数量的结果

对于降序结果，请使用DESC。但是，LIMIT用于获取固定数量的记录-

select *from yourTableName order by yourColumnName DESC LIMIT yourLimitNumber;

让我们首先创建一个表-

create table DemoTable (Id int, Name varchar(100));

示例

使用插入命令在表中插入一些记录-

insert into DemoTable values(100,John); insert into DemoTable values(101,Chris); insert into DemoTable values(102,Robert); insert into DemoTable values(103,Bob); insert into DemoTable values(104,Adam); insert into DemoTable values(105,James);

使用select语句显示表中的所有记录-

select *from DemoTable;

输出结果

+------+--------+ | Id | Name | +------+--------+ | 100 | John | | 101 | Chris | | 102 | Robert | | 103 | Bob | | 104 | Adam | | 105 | James | +------+--------+ 6 rows in set (0.00 sec)

以降序获取固定数量的记录-

select *from DemoTable order by Name DESC LIMIT 3;

输出结果

+------+--------+ | Id | Name | +------+--------+ | 102 | Robert | | 100 | John | | 105 | James | +------+--------+ 3 rows in set (0.00 sec)
