Oracle(90)数据库如何创建用户(User)

-- 使用SQL*Plus连接到数据库
sqlplus sys as sysdba
-- 或者使用其他工具如SQL Developer连接

CREATE USER my_user 
IDENTIFIED BY my_password 
DEFAULT TABLESPACE users 
TEMPORARY TABLESPACE temp;

-- 分配CONNECT和RESOURCE角色
GRANT CONNECT, RESOURCE TO my_user;

-- 分配特定的系统权限
GRANT CREATE SESSION TO my_user;
GRANT CREATE TABLE TO my_user;
GRANT CREATE VIEW TO my_user;
GRANT CREATE PROCEDURE TO my_user;
GRANT CREATE SEQUENCE TO my_user;

-- 分配特定的对象权限
GRANT SELECT, INSERT, UPDATE, DELETE ON my_schema.my_table TO my_user;

ALTER USER my_user QUOTA 100M ON users;

-- 锁定用户账户
ALTER USER my_user ACCOUNT LOCK;

-- 解锁用户账户
ALTER USER my_user ACCOUNT UNLOCK;

-- 连接到数据库
-- sqlplus sys as sysdba

-- 创建用户
CREATE USER my_user 
IDENTIFIED BY my_password 
DEFAULT TABLESPACE users 
TEMPORARY TABLESPACE temp;

-- 分配CONNECT和RESOURCE角色
GRANT CONNECT, RESOURCE TO my_user;

-- 分配特定的系统权限
GRANT CREATE SESSION TO my_user;
GRANT CREATE TABLE TO my_user;
GRANT CREATE VIEW TO my_user;
GRANT CREATE PROCEDURE TO my_user;
GRANT CREATE SEQUENCE TO my_user;

-- 分配特定的对象权限
GRANT SELECT, INSERT, UPDATE, DELETE ON my_schema.my_table TO my_user;

-- 为用户分配表空间配额
ALTER USER my_user QUOTA 100M ON users;

-- 解锁用户账户
ALTER USER my_user ACCOUNT UNLOCK;

-- 确认用户创建和权限分配成功
SELECT username, account_status FROM dba_users WHERE username = 'MY_USER';

-- 使用新用户连接到数据库
sqlplus my_user/my_password@your_database

-- 创建一个表
CREATE TABLE test_table (id NUMBER, name VARCHAR2(50));

-- 插入数据
INSERT INTO test_table (id, name) VALUES (1, 'Test Name');

-- 查询数据
SELECT * FROM test_table;

-- 删除表
DROP TABLE test_table;
