MongoDB CREATE Database

MongoDB CREATE DATABASE syntax

The syntax format for MongoDB database creation is as follows:

Use database_name

If the database does not exist, create the database, or switch to the specified database.

Instance

The following example we created the database Runoob:

> Use runoobswitched to db runoob> dbrunoob>    

If you want to see all the databases, you can use the show dbs command:

> show dbsshow dbslocal  0.078GB0.078GB>     

As you can see, the database Runoob we just created is not in the list of databases, and to display it, we need to insert some data into the Runoob database.

> Db.. Insert ({ "name" : "Rookie Tutorial" writeresult ({  "ninserted"  : 1  }) > show Dbslocal 0.078gbrunoob 0.078gb< Span class= "PLN" >test 0.078gb>     

The default database in MongoDB is test, and if you do not create a new database, the collection will be stored in the test database.
