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)
