MongoDB中怎么重命名database

本篇文章为大家展示了MongoDB中怎么重命名database，内容简明扼要并且容易理解，绝对能使你眼前一亮，通过这篇文章的详细介绍希望你能有所收获。

重命名database脚本如下:

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});

}

测试：

> 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
