mysql 查询结果导出文件：

select logtime, operatingsystem, imeifrom GameCenterLogswhere    operatingsystem >= 1 and operatingsystem <=3group by operatingsystem,imeiinto outfile '/tmp_logs/tmp.csv'fields TERMINATED BY ',' OPTIONALLY ENCLOSED BY '#' LINES TERMINATED BY '\r\n'

fields TERMINATED BY ',' 设置字段的分割符

OPTIONALLY ENCLOSED BY '#' 设置字段内容若为字符串，则使用'#'包含

LINES TERMINATED BY '\r\n' 数据行分割符

导出文件内容：

1453513680,3,#hello word#\r\n1453515470,2,#title content#\r\n

mysql命令行导入文件到数据库：

load data infile '/tmp_logs/tmp.csv' into table GameCenterDAULogs fields terminated by ',' OPTIONALLY ENCLOSED BY '#' lines terminated by '\r\n'

有可能操作系统不同，导出的csv文件的数据行分隔符不一定为\r\n，可以使用cat -A /tmp_logs/tmp.csv 查看结尾符
