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

switched to db test_new

> show tables
