MySQL select into outfile用法

select into outfile用法

SELECT ... FROM TABLE_A INTO OUTFILE "/path/to/file" FIELDS TERMINATED BY ',' OPTIONALLY ENCLOSED BY '"' LINES TERMINATED BY '\n';

load data infile用法

LOAD DATA INFILE "/path/to/file" INTO TABLE table_name; 注意：若是導出時用到了FIELDS TERMINATED BY ',' OPTIONALLY ENCLOSED BY '"' LINES TERMINATED BY '\n'語句，那麼LODA時也要加上一樣的分隔限制語句。還要注意編碼問題。

解決select into outfile，不能導出到自定義目錄問題

Recent Ubuntu Server Editions (such as 10.04) ship with AppArmor and MySQL's profile might be in enforcing mode by default. You can check this by executing sudo aa-status like so:

> sudo aa-status
    5 profiles are loaded. 5 profiles are in enforce mode. /usr/lib/connman/scripts/dhclient-script /sbin/dhclient3 /usr/sbin/tcpdump /usr/lib/NetworkManager/nm-dhcp-client.action /usr/sbin/mysqld 0 profiles are in complain mode. 1 processes have profiles defined. 1 processes are in enforce mode : /usr/sbin/mysqld (1089) 0 processes are in complain mode.

If mysqld is included in enforce mode, then it is the one probably denying the write. Entries would also be written in /var/log/messages when AppArmor blocks the writes/accesses. What you can do is edit /etc/apparmor.d/usr.sbin.mysqld and add /data/ and /data/* near the bottom like so:

/usr/sbin/mysqld { ... /var/log/mysql/ r, /var/log/mysql/* rw, /var/run/mysqld/mysqld.pid w, /var/run/mysqld/mysqld.sock w, /data/ r, /data/* rw, }

And then make AppArmor reload the profiles.

> sudo /etc/init.d/apparmor reload
