导出数据库

– 导出dbname表结构

mysqldump -uroot -p123456 -d dbname > dbname.sql

– 导出dbname表数据

mysqldump -uroot -p123456 -t dbname > dbname.sql

– 导出dbname表结构和数据

mysqldump -uroot -p123456 dbname > dbname.sql

导出数据库中指定表

– 导出dbname下的test表结构

mysqldump -uroot -p123456 -d dbname test > test.sql

– 导出dbname下的test表数据

mysqldump -uroot -p123456 -t dbname test > test.sql

– 导出dbname下的test表结构和数据

mysqldump -uroot -p123456 dbname test > test.sql

还原

– 创建数据库

CREATE DATABASE dbname DEFAULT CHARACTER SET utf8 COLLATE utf8_general_ci;

– 还原数据库

mysql -uroot -p123456 dbname < /path/dbname.sql

– 还原数据库

source dbname.sql

– 查看表结构

desc wp_users;
 
show create table wp_users \G;
SELECT INTO OUTFILE导出
 
SELECT * INTO OUTFILE 'temp.txt'
 
FIELDS TERMINATED BY ',' OPTIONALLY ENCLOSED BY '"' LINES TERMINATED BY '\n'
 
FROM table_name
 
WHERE createtime < 1382716800;
LOAD DATA 导入
 
LOAD DATA INFILE '/home/temp.txt'
 
INTO TABLE table_name
 
FIELDS TERMINATED BY ',' OPTIONALLY ENCLOSED BY '"' LINES TERMINATED BY '\n'

(product_id,uuid,mac,monitor,win_version,ip,createtime) ;
注： 从本地导入远程服务器需使用LOAD DATA LOCAL INFILE

确保local_infile打开且有权限的情况下LOAD DATA若报错：message:The used command is not allowed with this MySQL version

1.mysql_connect指定第五个参数128测试，即mysql_connect($host, $user, $pwd, false, CLIENT_LOCAL_FILES)

2.PHP中mysql扩展版本（待确认）
