一，CSV格式

採用csv格式匯入匯出mysql中的資料都會非常快，經過測試，通過csv格式匯入1566w的資料只需要花了112mins。

• 1，匯出csv格式

into outfile '/tmp/test.csv'   
fields terminated by ',' optionally enclosed by '"' escaped by '"'   
lines terminated by '\r\n'; 

• 2，匯入csv格式

 load data infile '/tmp/test.csv'  
into table test_info   
fields terminated by
 
 ','  optionally enclosed by '"' escaped by '"'  
lines terminated by '\r\n';

• 3,錯誤處理。
  ERROR 1290 (HY000): The MySQL server is running with the –secure-file-priv option so it cannot execute this statement
  通過命令：
  SHOW VARIABLES LIKE "secure_file_priv";
  檢視相應的檔案在哪裡。
