原文�q�接�Q?br /> http://blog.csdn.net/fenglibing/archive/2007/10/11/1820153.aspx
语法�Q?/div>

				LOAD DATA [LOW_PRIORITY | CONCURRENT] [LOCAL] INFILE 'file_name'

				    INTO TABLE tbl_name

				    [CHARACTER SET charset_name]

				        [TERMINATED BY 'string']

				    [IGNORE number LINES]

				    [(col_name_or_user_var,...)]

				    [SET col_name = expr,...]

使用如下命��o�Q?/div>

LOAD DATA LOCAL INFILE 'C:\\stu.txt' INTO TABLE stu;

因�ؓ�q�是一条SQL语句�Q�你同样可以在你�?strong>JAVA�E�序序中用：

st.execute(“LOAD DATA LOCAL INFILE 'C:\\stu.txt' INTO TABLE stu�?;

(st表示Statement的一个实例变量，假设数据库连接，st的初使化已经完成)

创徏stu表：

create table stu_other(id int auto_increment primary key,stu_name varchar(50),age int);

然后创徏一个文本文件“stu.txt”，每行包含一个记录，攑֜�C盘的根目录下�?strong>默认的字�D�分隔符�?/strong>(tab)�Q�你可以更改�Q�下面说明。�ƈ且以CREATE TABLE语句中列出的列次序给�?/strong>。对于丢��q��?例如未知的性别�Q�或仍然�zȝ��的动物的��M��日期)�Q�你可以使用NULL倹{��ؓ了在你的文本文�g中表�C��些内容，使用\N�Q�反斜线�Q�字母N�Q��?/div>

如stu.txt的内容如下：

100001    FLB100001     100001

100002    FLB100002     100002

100003    FLB100003     100003

100004    FLB100004     100004

100005    FLB100005     100005

100006    FLB100006     100006

100007    FLB100007     100007

100008    FLB100008     100008

�?/div>
�q�里我用的是table分开�?/div>

要想��文本文件“stu.txt”装载到stu表中�Q��用这个命令：

mysql> LOAD DATA LOCAL INFILE 'c:\\stu.txt' INTO TABLE stu;

�q�里没有指定字段分隔�W�，以及行的�l�止�W�，默认情况下是�q�样的：

字段分隔�W�：

FIELDS TERMINATED BY '\t' ENCLOSED BY '' ESCAPED BY '\\'

其中�?\t'��p��C�是字段分隔�W��ؓtab键，如果不想更改�Q�那��把FIELDS TERMINATED BY '\t'中的'\t'改在你自��q��分隔�W�。将执行命��o�Ҏ��q�样�Q?/span>

mysql> LOAD DATA LOCAL INFILE 'c:\stu.txt' INTO TABLE stu fields terminated by �?�?

�q�里我用的是�I�格�?/div>
行终止符�Q?/strong>

LINES TERMINATED BY '\n' STARTING BY ''

��h��意如果用Windows中的�~�辑器（使用\r\n做�ؓ行的�l�束�W�）创徏文�g�Q�应使用�Q?/div>

mysql> LOAD DATA LOCAL INFILE 'C:\\stu.txt' INTO TABLE stu

    -> LINES TERMINATED BY '\r\n';

�Q�在�q�行OS X的Apple��Z��Q�应使用行结束符'\r'。）

如果你愿意，你能明确地在LOAD DATA语句中指出列值的分隔�W�和行尾标记�Q�但是默认标记是定位�W�和换行�W�。这对读入文件“stu.txt”的语句已经��_��?/div>

另外�Q�还可以使用SELECT ... INTO OUTFILE ��数据导入到外部文�g中，如下�Q?/strong>

select * from stu_t into outfile "c:\\stu_t.txt";

不过�Q�没有按记录自动分行

�q�样才能够换行：

select * from stu_t into outfile "c:\\stu_t.txt" lines terminated by '\r\n';

所有实例都是经�q�测试的�Q�运行成功�?/div>

windows下安装解压版mysql

想飞的鱼 — Tue, 26 Dec 2006 07:39:00 GMT
1、下载mysql
       http://dev.mysql.com/downloads/
2、将mysql解压到待安装目录�Q��?MYSQL_HOME%表示�?br />3、编辑my.ini文�g(该文件放到C:\windows目录�?�Q�内容如下：

[mysqld]
#default-character-set=gbk
basedir=%MYSQL_HOME%
datadir=%MYSQL_HOME%/data

[WinMySQLadmin]
Server=%MYSQL_HOME%/bin/mysqld-nt.exe
user=root
password=

4、打开windows的cmd命��o�H�口�Q�进入到%MYSQL_HOME%\bin�?br />5、执行命令： mysqld-nt.exe --install �Q�安装到windows的服务）
6、执行命令： net start mysql
一般情况下�Q�这��h��作后�Q�mysql安装完成�?br />
注：
1、如果以前系�l�存在mysql。则�q�入以前�pȝ��存在的mysql目录,执行 mysqld-nt.exe --remove(先从�pȝ��中移
      除mysql服务)在开始执行上面第4步�?br />2、如果出�?067错误�Q�一般是my.ini文�g配置问题。更改my.ini文�g使之�W�合本地情况.

[转]ysql4.1以上版本�q�接时出现Client does not support authentication protocol问题解决办法

想飞的鱼 — Sat, 23 Dec 2006 07:50:00 GMT

mysql4.1以上版本�q�接时出现Client does not support authentication protocol问题解决办法

shell> mysql
Client does not support authentication protocol requested
by server; consider upgrading MySQL client

官方的说法是

MySQL 4.1 and up uses an authentication protocol based on a password hashing algorithm that is incompatible with that used by older clients. .....

如果你升�U�mysql�?.1以上版本后遇��C��上问�?请先��定你的mysql client �?.1或者更高版�?(WINDOWS下有问题你就直接跛_��下面看解��x��法了,因�ؓMYSQL 在WINDOWS是client和server一赯��上了�?

请��用以下两�U�方法之一

其一:

mysql> SET PASSWORD FOR -> 'some_user'@'some_host' = OLD_PASSWORD('newpwd');

其二:

mysql> UPDATE mysql.user SET Password = OLD_PASSWORD('newpwd') -> WHERE Host = 'some_host' AND User = 'some_user'; mysql> FLUSH PRIVILEGES;

上面�U�色的部分请按自己实际情况修�?...

�q�样做后,�q�接��׃��正常了@!

Linux�q�_��Q�忘记mysql的root密码解决办法

想飞的鱼 — Sat, 23 Dec 2006 05:43:00 GMT
转：http://www.domsn.net/index.php?play=reply&id=490

当忘记MySQL的root密码的时候，可以�q�行如下的步骤重新设�|�MySQL的root密码�Q?

■■Linux的��^台■�?

1�Q�首先确认服务器��Z��安全的状态，也就是没有�h能够��L��地连接MySQL数据库�?
因�ؓ在重新设�|�MySQL的root密码的期��_��MySQL数据库完全出于没有密码保护的
状态下�Q�其他的用户也可以�Q意地��d��和修改MySQL的信息。可以采用将MySQL�?
外的端口��闭�Q��ƈ且停止Apache以及所有的用户�q�程的方法实现服务器的准安全
状态。最安全的状态是到服务器的Console上面操作�Q��ƈ且拔掉网�Uѝ�?

2�Q�修改MySQL的登录设�|�：
# vi /etc/my.cnf
在[mysqld]的段中加上一句：skip-grant-tables
例如�Q?
[mysqld]
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
skip-grant-tables
保存�q�且退出vi�?

3�Q�重新启动mysqld
# /etc/init.d/mysqld restart
Stopping MySQL: [ OK ]
Starting MySQL: [ OK ]

4�Q�登录�ƈ修改MySQL的root密码
# /usr/bin/mysql
Welcome to the MySQL monitor. Commands end with ; or \g.
Your MySQL connection id is 3 to server version: 3.23.56

Type 'help;' or '\h' for help. Type '\c' to clear the buffer.

mysql> USE mysql ;
Reading table information for completion of table and column names
You can turn off this feature to get a quicker startup with -A

Database changed
mysql> UPDATE user SET Password = password ( 'new-password' ) WHERE User = 'root' ;
Query OK, 0 rows affected (0.00 sec)
Rows matched: 2 Changed: 0 Warnings: 0

mysql> flush privileges ;
Query OK, 0 rows affected (0.01 sec)

mysql> quit
Bye

5�Q�将MySQL的登录设�|�修改回�?
# vi /etc/my.cnf
��刚才在[mysqld]的段中加上的skip-grant-tables删除
保存�q�且退出vi�?

6�Q�重新启动mysqld
# /etc/init.d/mysqld restart
Stopping MySQL: [ OK ]
Starting MySQL: [ OK ]

7�Q�恢复服务器的正常工作状�?
��步骤一中的操作逆向操作。恢复服务器的工作状态�?
