How Does oracle authorize users to create tables only in the specified tablespace?

First, view the permissions that the user has, revoke irrelevant permissions, and then view the permissions of the user on the table space.
1. view User Permissions
1. view the system permissions of the current user
Select * from session_privs;
2. view all roles in the database
Selec * from dba_roles;
3. view the maximum number of roles supported by the database
SQL> show parameter role

Max_enabled_roles integer 150 -- this value can be modified

OS _roles boolean FALSE

Remote_ OS _roles boolean FALSE
4. view the roles of the current user
Select * from session_roles;

5. view the nested relationship of the role and the assigned user
Select * from dba_role_privs order by 1;

6. Other commands for viewing roles and permissions
Select * from role_sys_privs;
Select * from dba_sys_privs;

2. view User tablespace Permissions
SQL> select * from user_ts_quotas;
If you can operate on other tablespaces, modify the user;

How does an Oracle database create a user and create a tablespace for the user?

Create a tablespace
Create tablespace table name datafile 'data filename 'size tablespace size;

Create user
Create user Username identified by password default tablespace table;

After creating a user, you must authorize the user to use it. First, you must authorize the login permission.
Grant create session to user name
Then grant other permissions.
