Create a new database user

Create a new database user and authorize

There are two built-in users inside oracle: system and sys. Users can log in directly to the system user to create other users because system has the authority to create other users. When installing oracle, the user or system administrator can first create a user for himself.

Syntax [create user]: create user username identified by password [ie password];

Example: create user dsdb identified by manager;

Syntax [change user]: alter user username identified by password [changed password];

Example: alter user test identified by 123456;
