在单个查询中实现 MySQL LIMIT 和 OFFSET，说明其区别

LIMIT 说明您想要多少条记录，而 OFFSET 给出从给定位置 +1 开始的记录。让我们首先创建一个表 −
mysql> create table DemoTable -> ( -> Name varchar(100) -> ); Query OK, 0 rows affected (1.33 sec)
使用 insert 命令在表中插入一些记录 −
mysql> insert into DemoTable values('John');
Query OK, 1 row affected (0.13 sec)
mysql> insert into DemoTable values('Chris');
Query OK, 1 row affected (0.27 sec)
mysql> insert into DemoTable values('David');
Query OK, 1 row affected (0.27 sec)
mysql> insert into DemoTable values('Bob');
Query OK, 1 row affected (0.26 sec)
mysql> insert into DemoTable values('Sam');
Query OK, 1 row affected (0.22 sec)
mysql> insert into DemoTable values('Mike');
Query OK, 1 row affected (0.59 sec)
mysql> insert into DemoTable values('Carol');
Query OK, 1 row affected (0.14 sec)
mysql> insert into DemoTable values('Robert');
Query OK, 1 row affected (0.60 sec)
使用 select 语句显示表中的所有记录 −
mysql> select *from DemoTable;
输出
这将产生以下输出 −
+--------+ | Name | +--------+ | John | | Chris | | David | | Bob | | Sam | | Mike | | Carol | | Robert | +--------+ 8 rows in set (0.00 sec)
以下是实现 MySQL 限制偏移量的查询 −
mysql> select *from DemoTable limit 4 offset 3;
输出
这将产生以下输出 −
+-------+ | Name | +-------+ | Bob | | Sam | | Mike | | Carol | +-------+ 4 rows in set (0.00 sec)
