本文實(shí)例講述了mysql實(shí)現(xiàn)查詢(xún)結(jié)果導(dǎo)出csv文件及導(dǎo)入csv文件到數(shù)據(jù)庫(kù)操作。分享給大家供大家參考，具體如下：

mysql 查詢(xún)結(jié)果導(dǎo)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 ',' 設(shè)置字段的分割符

OPTIONALLY ENCLOSED BY '#' 設(shè)置字段內(nèi)容若為字符串，則使用'#'包含

LINES TERMINATED BY '\r\n' 數(shù)據(jù)行分割符

導(dǎo)出文件內(nèi)容：

1453513680,3,#hello word#\r\n
1453515470,2,#title content#\r\n

mysql命令行導(dǎo)入csv文件到數(shù)據(jù)庫(kù)：

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

有可能操作系統(tǒng)不同，導(dǎo)出的csv文件的數(shù)據(jù)行分隔符不一定為\r\n，可以使用cat -A /tmp_logs/tmp.csv 查看結(jié)尾符
