本篇文章為大家展示了MongoDB中怎么重命名database，內(nèi)容簡(jiǎn)明扼要并且容易理解，絕對(duì)能使你眼前一亮，通過(guò)這篇文章的詳細(xì)介紹希望你能有所收獲。

重命名database腳本如下:

var source = "source";

var dest = "dest";

var colls = db.getSiblingDB(source).getCollectionNames();

for (var i = 0; i < colls.length; i++) {

var from = source + "." + colls[i];

var to = dest + "." + colls[i];

db.adminCommand({renameCollection: from, to: to});

}

測(cè)試：

> var source = "test";

> var dest = "test_new";

> var colls = db.getSiblingDB(source).getCollectionNames();

> for (var i = 0; i < colls.length; i++) {

... var from = source + "." + colls[i];

... var to = dest + "." + colls[i];

... db.adminCommand({renameCollection: from, to: to});

... }

{ "ok" : 1 }

> use test_new

switched to db test_new

> show tables

test

aaa

bbb

log

task

push_log

push_task
