    lines terminated by ' '
    enclosed by ''
    escapsed by '\' as: select * from test into outfile 'test.txt' fields terminated by ',' lines terminated by '?' 表示导出的数据中,字段之间用 ','分隔,行之间用 '?'分隔 as: select * from test into outfile 'test.txt' fields terminated by ',' optionally enclosed by '"' lines terminated by '?' 表示字符是用 '"'包围的,如果全部用'"'包围,则不用加上 optionally 也可用dumpfile,但是所有行彼此挨着,值与行之间没有任何标志 as: select * from test into dumpfile 'test.dump' 载入数据数据表中 load data [low_priority][concurrent][local] infile 'filename' [replace] into table tablename [fields terminated by literal] [lines terminated by literal] as: load data infile 'test.txt' replace into table test; as: load data infile 'test.txt' replace into table test fields terminated by ',' line terminated by '?'
