请问这样的问题的MySql查询语句怎么写？

[ga6840]

现在有一个表，名字就叫作comment吧：
+------+
| id |
+------+
| 102 |
| 203 |
| 213 |
| 222 |
| 258 |
| 288 |
| 298 |
| 322 |
+------+

我想给他按照id顺序加上编号：

+---+-----+
| 编号 | id |
+---+-----+
| 1 | 102 |
| 2 | 203 |
| 3 | 213 |
| 4 | 222 |
| 5 | 258 |
| 6 | 288 |
| 7 | 298 |
| 8 | 322 |
+----+----+
这个我能用以下语句实现：

set @floor := 0; select @floor := @floor + 1 as '编号', comment.* from comment

然后我想得到编号4和其后面的2行，在这张表里就会得到如下结果：

+---+-----+
| 编号 | id |
+---+-----+
| 4 | 222 |
| 5 | 258 |
| 6 | 288 |
+----+----+

按照这个实例的步骤，我想请问一般情况下的MySql语句怎么写。我才接触Sql，希望大家能帮助我。谢谢

select 编号,id From temp where 编号 >=4 And 编号 <= 4+2
不行吗？呵呵

SQL不好写，用存储过程或则函数什么的就简单了。

----增加id
alter table comment add column id int auto_increment not null;
--到编号4和其后面的2行

select * from comment order by id limit 4,2;

修改编号列number

mysql> SELECT * FROM TA4;
+------+
| ID   |
+------+
|  102 |
|  203 |
|  213 |
|  222 |
|  258 |
|  288 |
|  298 |
|  322 |
+------+
8 rows in set (0.00 sec)

mysql> SET @NUM:= 0;
Query OK, 0 rows affected (0.00 sec)

mysql> SELECT * FROM (
    -> SELECT *,@NUM:= @NUM + 1 AS '编号' FROM TA4) A ORDER BY 编号 LIMIT 3,3;
+------+------+
| ID   | 编号     |
+------+------+
|  222 |    4 |
|  258 |    5 |
|  288 |    6 |
+------+------+
3 rows in set (0.00 sec)

MySQL中的ROWNUM的实现
MySQL 几乎模拟了 Oracle,SQL Server等商业数据库的大部分功能，函数。但很可惜，到目前的版本(5.1.33)为止,仍没有实现ROWNUM这个功能。 下面介绍几种具体的实现方法.建立实验环境如下mysql> create table tbl ( -> id int primary key, -> col int -> );Que...

[ACMAIN_CHM]

set @floor := 0; select * from (select @floor := @floor + 1 as `编号`, comment.* from comment) t where `编号`>=4 limit 3;

[wwwwb]

or

mysql> SET @NUM:= 0;
Query OK, 0 rows affected (0.00 sec)

mysql> SELECT * FROM (SELECT *,@NUM:= @NUM + 1 AS '编号' FROM TA4) A
    -> WHERE 编号>=4 ORDER BY 编号 LIMIT 3;
+------+------+
| ID   | 编号     |
+------+------+
|  222 |    4 |
|  258 |    5 |
|  288 |    6 |
+------+------+
3 rows in set (0.00 sec)

谢谢!
wwwwb在5楼的回复很好地解决了问题：

mysql> set @num:=0; select floor from (select floor, @num:=@num+1 as '编号' from comment order by floor) a order by '编号' limit 2,3;
Query OK, 0 rows affected (0.00 sec)

+-------+
| floor |
+-------+
|   102 |
|   203 |
|   213 |
+-------+
3 rows in set (0.00 sec)

但是7楼和wwwwb在8楼的语句我试了一下，在我这里没有结果，不知道什么原因：

set @num:=0; select * from (SELECT *, @num:= @num + 1 AS '编号' FROM comment) t where '编号'>4 limit 3;
Query OK, 0 rows affected (0.00 sec)

Empty set, 1 warning (0.00 sec)

mysql> set @num:=0; select * from (select *, @num:=@num+1 as '编号' from comment) a where '编 号'>4 order by '编号' limit 3;
Query OK, 0 rows affected (0.00 sec)

Empty set, 1 warning (0.00 sec)

我先给分了，不过想问一下wwwwb，有什么好的SQL书籍推荐一下吗？谢谢你了

[wwwwb]

我是用你1楼的数据测试的，没有问题，
SHOW WARNINGS
看看结果

sql cookbook
高性能 mysql

嗯，谢谢。

[ga6840]

mysql> show warnings;
+---------+------+-----------------------------------------+
