MySQL 如何使用LIMIT命令对记录进行排序并获取部分记录

首先创建一个表 –

mysql> create table DemoTable679(FirstName varchar(100)); 
Query OK, 0 rows affected (0.44 sec)

使用插入命令将一些记录插入表中 –

mysql> insert into DemoTable679 values('John'); 
Query OK, 1 row affected (0.14 sec) 
mysql> insert into DemoTable679 values('Chris'); 
Query OK, 1 row affected (0.11 sec) 
mysql> insert into DemoTable679 values('David'); 
Query OK, 1 row affected (0.19 sec) 
mysql> insert into DemoTable679 values('Bob'); 
Query OK, 1 row affected (0.14 sec) 
mysql> insert into DemoTable679 values('Mike'); 
Query OK, 1 row affected (0.11 sec) 
mysql> insert into DemoTable679 values('Sam'); 
Query OK, 1 row affected (0.15 sec) 
mysql> insert into DemoTable679 values('Robert'); 
Query OK, 1 row affected (0.15 sec)

使用select语句显示表中的所有记录 –

mysql> select *from DemoTable679;

将会产生以下输出 –

+-----------+ 
| FirstName | 
+-----------+ 
| John      | 
| Chris     | 
| David     | 
| Bob       | 
| Mike      | 
| Sam       | 
| Robert    | 
+-----------+ 
7 rows in set (0.00 sec)

以下是在MySQL中选择最后n行的查询方法。 这里，我们首先按ASC排序并显示前4条记录 –

mysql> select * from DemoTable679 order by FirstName Limit 0,4;

将会产生以下输出 –

+-----------+ 
| FirstName | 
+-----------+ 
| Bob       | 
| Chris     | 
| David     | 
| John      | 
+-----------+ 
4 rows in set (0.00 sec)
