Posted 2020-12-28 梦想_行人

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）
