在MySQL5.0.15-nt-max下进行测试。

1.新建一张临时表(MyISAM或者InnoDB类型的都可以)，本测试表没有使用自增列。

CREATE TABLE `andkylee` (
`id` int(11) NOT NULL,
`name` varchar(30) default NULL,
`sex` char(1) NOT NULL,
`age` smallint(6) default NULL,
`note` varchar(100) default NULL
) ENGINE=MyISAM DEFAULT CHARSET=utf8;

2.插入测试数据。在这里尤其介绍一种插入大量测试数据的方法。

先插入2条数据：

insert into andkylee
values(1,'hanyuliu','F',25,'aaaaaaaaaa'),(2,'andkylee','F',33,'bbbbbbbbbb');

批量插入数据：

在没有自增列的情况下，用下面的语句来实现插入“重复”数据。

insert into andkylee
select id+(select max(id) from andkylee),name,sex,age,note from andkylee;

本语句能够复制表已有的所有记录，并且能够实现“主键列”自增。

循环插入重复数据，使得表数据行数以指数方式增长。再把已有的数据插入到表内，行数变为以前的2倍。

insert into andkylee
select id+(select max(id) from andkylee),name,sex,age,note from andkylee;
mysql> select count(*) from andkylee;
+----------+
| count(*) |
+----------+
| 4 |
+----------+
1 row in set (0.05 sec)

重复上面的语句，执行10次之后，表内的数据行数为：2048

测试数据情况为：

mysql> select *from andkylee;
+------+----------+-----+------+------------+
| id   | name     | sex | age  | note       |
+------+----------+-----+------+------------+
|    1 | hanyuliu | F   |   25 | aaaaaaaaaa |
|    2 | andkylee | F   |   33 | bbbbbbbbbb |
|    3 | hanyuliu | F   |   25 | aaaaaaaaaa |
|    4 | andkylee | F   |   33 | bbbbbbbbbb |
.....
| 2043 | hanyuliu | F   |   25 | aaaaaaaaaa |
| 2044 | andkylee | F   |   33 | bbbbbbbbbb |
| 2045 | hanyuliu | F   |   25 | aaaaaaaaaa |
| 2046 | andkylee | F   |   33 | bbbbbbbbbb |
| 2047 | hanyuliu | F   |   25 | aaaaaaaaaa |
| 2048 | andkylee | F   |   33 | bbbbbbbbbb |
+------+----------+-----+------+------------+
2048 rows in set (0.08 sec)

3.选择第100至300行数据

这里不得不介绍limit这个关键字了。

limit关键字的使用方式为：

(SQL statement) limit row_position,row_count

其中：(SQL statement) 为完整的SQL语句，就是普通的sql语句，以前的语句该怎么写的还是怎么写。

limit 是个关键字，在MySQL中关键字是不区分大小写的，Limit,limit,LIMIT对于数据库引擎来说都是一样的。

后面是两个参数，row_position表示起始行，更确切的说应该是偏移行，自然row_position是从0开始的。也就是说第一行的偏移行数为0.

要是想返回从第二行开始的记录，就将row_position指定为1.

第二个参数：row_count表示返回的行数。这个很简单，不赘述。

因此，要返回第100至300行数据，需要指定偏移行号为99，并且行数为201.

语句为：

select *from andkylee LimiT 99,201;

返回结果为：

mysql> select *from andkylee LimiT 99,201;
+-----+----------+-----+------+------------+
| id  | name     | sex | age  | note       |
+-----+----------+-----+------+------------+

4. 功能完善。

通过第3步骤中的两个结果集进行对比，我们可以发现，MySQL中的limit关键字类似于一个伪列的功能。比oracle中的rownum要强大，在 oracle中要通过一次rownum再加一次虚拟列才能实现类似MySQL中的limit功能。因此limit功能存在优势的地方在于：不产生虚拟列。也就是说你不需要花费额外的功夫来处理列名列表了。最简单的就是直接用星号*,开发人员在编写存错过程的时候比较省事了。
