mongodb里的集合数据迁移到mysql库

1，在mongodb上导出数据，写个脚步expmongo.sh，shell脚本如下

#!/bin/sh
datestr=`date '+%Y-%m-%d'`
/usr/local/mongodb/mongodb-linux-x86_64-2.4.4/bin/mongoexport -im_user -pxxxeedd -d im -c message -f txnType,issNo,sn,merchantorder,paymentType,paymentTime,authNo,expDate,cardNo,amount,batchNo,refNo,merchantName,voucher,acqNo --csv -o /tmp/im_$datestr.txt && sz /tmp/im_$datestr.txt

导出来的im数据，/tmp/im_$datestr.txt ，大概有6000多条记录。

类似这样的数据：

txnType,issNo,sn,merchantorder,paymentType,paymentTime,authNo,expDate,cardNo,amount,batchNo,refNo,merchantName,voucher,acqNo

“0”,”“,”WP14521000000342”,”“,”银行卡”,”1440050366667”,”“,”“,”6216615625”,”10”,”2”,”891094135928”,”厚味香味馆”,”000235”,””

“1”,,”WP14521000000342”,,,,,,,”10”,,,,,

“0”,”“,”WP14521000000422”,”“,”现金”,”1440050722137”,”“,”“,”“,”0.01”,”“,”“,”老裁缝家纺”,”“,”“

2，在mysql库里面，建一张存储mongodb的数据的表：

建表语句如下：

CREATE TABLE

sap_im

(

txnType

varchar(8) DEFAULT NULL,

issNo

varchar(128) DEFAULT NULL,

sn

varchar(128) DEFAULT NULL,

merchantorder

varchar(128) DEFAULT NULL,

paymentType

varchar(128) DEFAULT NULL,

paymentTime

varchar(128) DEFAULT NULL,

authNo

varchar(128) DEFAULT NULL,

expDate

varchar(128) DEFAULT NULL,

cardNo

varchar(128) DEFAULT NULL,

amount

varchar(128) DEFAULT NULL,

batchNo

varchar(128) DEFAULT NULL,

refNo

varchar(128) DEFAULT NULL,

merchantName

varchar(128) DEFAULT NULL,

voucher

varchar(128) DEFAULT NULL,

acqNo

varchar(128) DEFAULT NULL

) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4

3，导入到mysql里面

上传im_$datestr.txt到mysql服务器，先然后把导出文件改成表名字

mv /tmp/im_detail_2015-11-12.txt /tmp/sap_im.csv

开始导入：

mysql> LOAD DATA INFILE “/tmp/sap_im.csv” REPLACE INTO TABLE sap_im FIELDS TERMINATED BY ‘,’ OPTIONALLY ENCLOSED BY ‘”’ ESCAPED BY ‘”’ LINES TERMINATED BY ‘\r\n’;

Query OK, 1 row affected (0.02 sec)

Records: 1 Deleted: 0 Skipped: 0 Warnings: 0

mysql>

奇怪，这里只导入了第一行记录，估计是换行符的问题，去掉命令行的\r，将’\r\n’换成’\n’即可，如下所示：

mysql>

mysql>

mysql> LOAD DATA INFILE “/tmp/sap_im.csv” REPLACE INTO TABLE sap_im FIELDS TERMINATED BY ‘,’ OPTIONALLY ENCLOSED BY ‘”’ ESCAPED BY ‘”’ LINES TERMINATED BY ‘\n’;

Query OK, 6555 rows affected (1.81 sec)

Records: 6555 Deleted: 0 Skipped: 0 Warnings: 0

mysql>

最终正常导入了6000多条记录出来。
