MySQL自己提供了导入导出的工具，但有时我们需要仅仅导入导出单个表的数据，比如导入导出CSV文件，此时可以使用MySQL自动的命令来做导入导出工作。
导出语法如下：
SELECT * FROM [TABLE]
INTO OUTFILE \'[FILE]\'；
或者
SELECT * FROM [TABLE]
INTO OUTFILE \'[FILE]\'
FIELDS TERMINATED BY \',\'
OPTIONALLY ENCLOSED BY \'"\'
LINES TERMINATED BY \'\n\'；
下边是一个具体的导出的例子：
SELECT * FROM mytable
INTO OUTFILE \'/tmp/mytable.csv\'
FIELDS TERMINATED BY \',\'
OPTIONALLY ENCLOSED BY \'"\'
LINES TERMINATED BY \'\n\'；
导入语法如下：
LOAD DATA INFILE \'[FILE]\'
INTO TABLE [TABLE]；
或者
LOAD DATA INFILE \'[FILE]\'
INTO TABLE [TABLE]
FIELDS TERMINATED BY \',\'
OPTIONALLY ENCLOSED BY \'"\'
LINES TERMINATED BY \'\n\'；
下边是一个具体的导入的例子：
LOAD DATA INFILE \'/tmp/mytable.csv\'
INTO TABLE mytable
FIELDS TERMINATED BY \',\'
OPTIONALLY ENCLOSED BY \'"\'
LINES TERMINATED BY \'\n\';
