mysql 查询结果导出csv文件：
select logtime, operatingsystem, imeifrom GameCenterLogswhereoperatingsystem >= 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\n
1453515470,2,#title content#\r\n
mysql命令行导入csv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
