mysql导出文本文件，加分隔符

从mysql导出，再导入到oracle

#!/bin/sh

cd /u03/tools/machine_info
rm -f data/machine_info.txt

mysql -u用户名 -p密码 -h服务器IP -P端口 < select_machine_info.sql|awk -F"\t" ' {printf("%s|%s|%s|%s|%s|%s|%s|%s|%s|%s|%s|%s|%s|%s|%s|%s|%s|%s|%s\n", $1,$2,$3,$4,$5,$6,$7,$8,$9,$10,$11,$12,$13,$14,$15,$16,$17,$18,$19)}' >  data/machine_info.txt

mysql> select * into outfile 'D:/temp/20150410.txt' FIELDS TERMINATED BY ',
' from `2015-04-10`;

把命令存成sql，在shell里面执行

mysql -uroot -ppassword < update.sql  

a.sql

select DATE_SUB(sysdate(), INTERVAL  DAY), * into outfile '\data\player\equip.log' FIELDS TERMINATED BY ';' from `equip` limit ;

a.sh

cd  /data/player
rm -rf *
mysql -uroot -ppassword < a.sql
MYDATE=$(date +%Y%m%d)
mv equip.log equip--$MYDATE.log

SELECT INTO…OUTFILE语法：

select * from Table into outfile '/路径/文件名'
fields terminated by ','
enclosed by '"'
lines terminated by '\r\n'

(1)路径目录必须有读写权限777
(2)文件名必须唯一
(3)fields terminated by ','必须存在，否则打开的文件的列在同一的单元格中出现
(4)我验证的表结构为gbk的，否则出现乱码

●  fields子句：在FIELDS子句中有三个亚子句：TERMINATED BY、 [OPTIONALLY] ENCLOSED BY和ESCAPED BY。如果指定了FIELDS子句，则这三个亚子句中至少要指定一个。

（1）TERMINATED BY用来指定字段值之间的符号，例如，“TERMINATED BY ','”指定了逗号作为两个字段值之间的标志。

（2）ENCLOSED BY子句用来指定包裹文件中字符值的符号，例如，“ENCLOSED BY ' " '”表示文件中字符值放在双引号之间，若加上关键字OPTIONALLY表示所有的值都放在双引号之间。

（3）ESCAPED BY子句用来指定转义字符，例如，“ESCAPED BY '*'”将“*”指定为转义字符，取代“\”，如空格将表示为“*N”。

(4) LINES子句：在LINES子句中使用TERMINATED BY指定一行结束的标志，如“LINES TERMINATED BY '?'”表示一行以“?”作为结束标志。

导出mysql，并执行rsync

#
time=`date +%Y%m%d`
mysql -uroot -p'密码' -e "show databases;" >/tmp/database.txt
db=`cat /tmp/database.txt |grep _ws|awk -F'[ws_]+' '{print $2}'`
bak_path=/data/player_rsync/
for i in ${db[@]}
do
mkdir /data/player_rsync/$time/
chmod  /data/player_rsync/$time/
#mysqldump -uroot -p'密码' _ws${i}_branch  player_query_data > /data/player_rsync/$time/tw${i}.txt
mysqldump --tab='/data/player_rsync/'$time'/' --fields-terminated-by='|' -h 127.0.0.1 -u root -p'密码' _ws${i}_branch player_query_data
mv /data/player_rsync/$time/player_query_data.txt   /data/player_rsync/$time/game_tw${i}.txt
sed -i 's/^/playerquerydata|100'$i'|&/g' /data/player_rsync/$time/game_tw${i}.txt
done
sleep 

sed -i "s/\\\\|/\&/g"  /data/player_rsync/$time/*.txt
rm -r /data/player_rsync/$time/player_query_data.sql

rsync -vzrtp --progress --password-file=/etc/rsync.passwd /data/player_rsync/ qysql@127.0.0.1::qy_sql

num=`ls /data/player_rsync/|wc -l`

if [[ $num > 5 ]];then
file=`ls /data/player_rsync/|grep $time`
for a in ${file[@]}
do
cd $bak_path
rm -rf $a
done
fi

exit
