MongoDB 如何修改数据库名称

Question

如题，在命令行里运行修改已有数据库名称

Answer 1

There is no direct method, only copy and then delete:

db.copyDatabase('old_name', 'new_name'); 
use old_name 
db.dropDatabase();

is still an indirect solution, but WiredTigerthere is a more convenient solution for the storage engine: db.renameCollection.

use admin;
db.runCommand({renameCollection: "test.test", to: "test1.test"});

When you move all collections to a new library, it is equivalent to renaming the entire library. This will be much faster than copyDatabase.

Note: renameCollection cannot be used for shard sets
