Today, I will talk to you about how to import Mysql data into MongoDB. Many people may not know much about it. In order to make you understand better, the editor has summarized the following content for you. I hope you can get something according to this article.

(1) Export data bit csv files from mysql, such as:

Java code

SELECT * FROM APP_CALL_LOG_1362959187037 WHERE CREATE_TIME

< '2013-03-07 14:45:04' into outfile '/tmp/all_call_log_012.csv' fields terminated by ',' lines terminated by '\n'; 　　(2)导入csv文件到mongodb,如： 　　Java代码 　　bin/mongoimport --host 114.112.94.104 --port 27017 -d lb_v1_log -c APP_CALL_LOG --type csv --ignoreBlanks -f ID,IP,URI,URL,D_CODE,D_TYPE,UID,APP_FROM,CREATE 　　_TIME,USER_AGENT,REMARK -file /usr/local/all_call_log_012.csv 　　(3)对导入数据矫正处理,如: 　　Java代码 　　pmy_log_rs:PRIMARY>

Db.APP_CALL_LOG.update ({UID: "\ N"}, {$set: {'UID': null}}, false,true)

Pmy_log_rs:PRIMARY > db.APP_CALL_LOG.update ({IP: "\ N"}, {$set: {'IP': null}}, false,true)

Pmy_log_rs:PRIMARY > db.APP_CALL_LOG.update ({D_TYPE: "\ N"}, {$set: {'Down typewriter: null}}, false,true)

Pmy_log_rs:PRIMARY > db.APP_CALL_LOG.update ({D_CODE: "\ N"}, {$set: {'Down codes: null}}, false,true)

Pmy_log_rs:PRIMARY > db.APP_CALL_LOG.update ({CREATE_TIME: "\ N"}, {$set: {'CREATE_TIME': null}}, false,true)

Pmy_log_rs:PRIMARY > db.APP_CALL_LOG.update ({APP_FROM: "\ N"}, {$set: {'APP_FROM': null}}, false,true)

Pmy_log_rs:PRIMARY > db.APP_CALL_LOG.update ({URI: "\ N"}, {$set: {'URI': null}}, false,true)

Pmy_log_rs:PRIMARY > db.APP_CALL_LOG.update ({URL: "\ N"}, {$set: {'URL': null}}, false,true)

Pmy_log_rs:PRIMARY > db.APP_CALL_LOG.update ({USER_AGENT: "\ N"}, {$set: {'USER_AGENT': null}}, false,true)

Pmy_log_rs:PRIMARY > db.APP_CALL_LOG.update ({REMARK: "\ N"}, {$set: {'REMARK': null}}, false,true)

(4) Field type correction, such as:

Java code

Db.APP_CALL_LOG.find ({}) .forEach (function (x) {x.D_CODE = "" + x.During CODEX db.App) CALLLCODEX LOG.save (x)
