mysql实现查询结果导出csv文件及导入csv文件到数据库操作
作者:CyborgLin
本文实例讲述了mysql实现查询结果导出csv文件及导入csv文件到数据库操作。分享给大家供大家参考,具体如下:
mysql 查询结果导出csv文件:
select logtime, operatingsystem, imei
from GameCenterLogs
where
operatingsystem >= 1 and operatingsystem <=3
group by operatingsystem,imei
into 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
