• 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_generic_ci;

– 还原数据库
source dbbackup.sql;

– 还原数据库
mysql -uroot -p123456 dbname < dbnamebackup.sql;
– 查看表结构
desc tablename;
show create table tablename;

• select into outfile 导出

select * from outfile ‘temp.txt’
fields terminated by ‘,’ optionally enclosed by ‘"’ lines terminated by ‘\n’
from tablename
where createtime < 12345689;

• load data导入

load data file ‘/home/temp.txt’
into table tablename
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）
