匯出資料庫

-- 匯出dbname表結構
mysqldump -uroot -p123456 -d dbname > dbname.sql
 
-- 匯出dbname表資料
mysqldump -uroot -p123456 -t dbname > dbname.sql
 
-- 匯出dbname表結構和資料
mysqldump -uroot -p123456 dbname > dbname.sql

匯出資料庫中指定表

-- 匯出dbname下的test表結構
mysqldump -uroot -p123456 -d dbname test > test.sql
 
-- 匯出dbname下的test表資料
mysqldump -uroot -p123456 -t dbname test > test.sql
 
-- 匯出dbname下的test表結構和資料
mysqldump -uroot -p123456 dbname test > test.sql
 

還原

-- 建立資料庫
CREATE DATABASE dbname DEFAULT CHARACTER SET utf8 COLLATE utf8_general_ci;
 
-- 還原資料庫
mysql -uroot -p123456 dbname < /path/dbname.sql
 
-- 還原資料庫
source dbname.sql
 
-- 查看錶結構
desc wp_users;
show create table wp_users \G;

SELECT INTO OUTFILE匯出

SELECT * INTO OUTFILE 'temp.txt' 
FIELDS TERMINATED BY ',' OPTIONALLY ENCLOSED BY '"' LINES TERMINATED BY '\n' 
FROM table_name 
WHERE createtime < 1382716800;
 

LOAD DATA 匯入

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： 從本地匯入遠端伺服器需使用LOAD DATA LOCAL INFILE

確保local_infile開啟且有許可權的情況下LOAD DATA若報錯：message:The used command is not allowed with this MySQL version

1.mysql_connect指定第五個引數128測試，即mysql_connect($host, $user, $pwd, false, CLIENT_LOCAL_FILES)

2.PHP中mysql擴充套件版本（待確認）
