對於只備份單張表的備份與還原，通過SELECT命令，可以更快速的達到備份和恢復的目的；
以及通過此方法把一個數據庫中表的數據，導入至另一數據庫的表中去。
備份格式：SELECT * INTO OUTFILE '/PATH/TO/somefile.txt'
FROM table_name [WHERE CLAUSE];
#備份table_name表中的[或者備份滿足WHERE語句的數據]數據至服務器上保存。
註釋：table_name：需要備份的表 WHERE：滿足的條件，可選項。
/PATH/TO：服務器上的路徑目錄，且此目錄必須是執行SELECT語句的用戶有寫的權限，
否則無法備份。
還原格式：LOAD DATA INFILE '/PATH/TO/somefile.txt' INTO TABLE table_name;
註釋：table_name：需要還原的表的名稱，此表必須先在數據庫中存在。
/PATH/TO：備份所存放的路徑
mysql> CREATE TABLE tutor LIKE tutors; #仿照tutors表的框架創建一個空表tutor
實例：備份一個數據庫表的數據，導入至另一個數據庫表的數據；
mysql> USE jiaowu;
Database changed
mysql> SELECT * FROM tutors; #查詢表tutors的信息
