Creating a Database Using Commands

A database is a collection of tables, indexes, views, stored procedures, and operators. To make it easier to manage DDS DB instances, you can create a database by running commands on the newly-created DB instance. If the database does not exist, create the database and switch to the new database. If the database exists, directly switch to the database.

Prerequisites

A DDS instance has been connected. For details, see "Connecting to an Instance over a Public Network" and "Connecting to an Instance over a Private Network" in Document Database Service Getting Started.

Procedure

Create a database.
use dbname

dbname: indicates the name of the database to be created.

Figure 1 Creating databases
After a database is created, insert data into the database so that you can view the database in the database list.

Figure 2 Inserting data

There are three system databases created by default: admin, local, and test. If you directly insert data without creating a database, the data is inserted to the test database by default.
