Oracle 10 新增用户操作指南（oracle10添加用户）

Oracle 10g is a popular database management system that is widely used across different sectors, including businesses, governments, and educational institutions. It is known for its robustness, security, and scalability, making it a go-to choice for many users. This guide will provide a step-by-step process to create a new user in Oracle 10, along with code snippets to help you along the way.

Before we get started, it is important to understand the different types of users in Oracle 10. There are three types of users, including:

1. Database users: These users have privileges to interact with the database objects like tables, views, and stored procedures. They can also create, update, and delete tables.

2. Schemas: Schemas are like namespaces for database objects. They are used to group objects under one umbrella and provide a way to organize objects.

3. Operating system users: These users have access to the operating system level and are used to manage system resources.

Now, let’s dive into the steps to create a new user in Oracle 10.

Step 1: Connect to your Oracle 10 database using SQL*Plus

Open the command console on your system and connect to the Oracle 10 database using SQL*Plus. You will need to enter your username and password to gn access to the database.

Command:

sqlplus /nolog

To log in as a privileged user:

connect sys as sysdba

Enter the password when prompted.

Step 2: Create a new database user

Enter the following command to create a new database user.

Command:

create user NEWUSER identified by Password;

Here, NEWUSER is the username you want to create, and Password is the password for the user.

Step 3: Grant privileges to the new user

Next, you need to grant privileges to the new user so that they can interact with the database objects. Enter the following command to grant the necessary privileges:

Command:

grant connect, resource to NEWUSER;

Here, connect and resource are two privileges that allow the user to connect to the database and create tables, respectively.

Step 4: Grant specific privileges to the new user

You can also grant specific privileges to the user based on your requirements. For example, if you want the user to have read-only access to a specific table, you can grant select privilege to that table.

Command:

grant select on TABLENAME to NEWUSER;

Here, TABLENAME is the name of the table, and NEWUSER is the username you created earlier.

Step 5: Verify the user credentials

Once you have created the new user and granted the necessary privileges, you can verify the user credentials using the following command:

Command:

select * from dba_users where username=’NEWUSER’;

This command will display the detls of the newly created user, including their username, account status, and default tablespace.

In conclusion, creating a new user in Oracle 10 is a strghtforward process that involves a few simple steps. By following this guide and using the code snippets provided, you can create a new user easily and effectively, granting them the necessary privileges to interact with the database objects.
