HomeDatabaseMysql TutorialOracle收集用户的权限

【使用场景】系统上线前准备工作。一般迁移数据的时候经常使用导入dump文件的方法。由于是一个一个用户导入进去的,所以在导入过程中会报权限问题的错误(可以忽略),还必须在生产库授权系统才能正常工作。使用下面的脚本可以得到授权语句。
 
在UAT环境执行select语句,在生产环境执行grant语句,根据实际用户做相应的修改。
 
注意:查询的用户需要有查看dba_开头数据字典的权限,否则报出表或者视图不存在。

SELECT 'GRANT ' || T1.GRANTED_ROLE || ' TO ' || T1.GRANTEE || ';' AS TEXT
 
FROM DBA_ROLE_PRIVS T1

WHERE T1.GRANTEE IN ('ABOQ',

'AMLM',

'BOP',

'CREDIT',

'DATACORE',

'MDR2',

'METABASE',

'METABASE_CREDIT',

'REPORT',

'UPRR',

'WORK')

UNION ALL

SELECT 'GRANT ' || T2.PRIVILEGE || ' TO ' || T2.GRANTEE || ';' AS TEXT
 
FROM DBA_SYS_PRIVS T2

WHERE T2.GRANTEE IN ('ABOQ',

'AMLM',

'BOP',

'CREDIT',

'DATACORE',

'MDR2',

'METABASE',

'METABASE_CREDIT',

'REPORT',

'UPRR',

'WORK')

UNION ALL

SELECT 'GRANT ' || T3.PRIVILEGE || ' ON ' || T3.OWNER || '.' ||
 
T3.TABLE_NAME || ' TO ' || T3.GRANTEE || ';' AS TEXT
 
FROM DBA_TAB_PRIVS T3

WHERE T3.GRANTEE IN ('ABOQ',

'AMLM',

'BOP',

'CREDIT',

'DATACORE',

'MDR2',

'METABASE',

'METABASE_CREDIT',

'REPORT',

'UPRR',

'WORK');

这样写比较死板,,使用‘&’替换变量也很不好用,可以建立一个存储过程。

create or replace procedure user_priv(username in varchar2) as
 cursor v_cur is
 SELECT 'GRANT ' || T1.GRANTED_ROLE || ' TO ' || T1.GRANTEE || ';' AS TEXT
 FROM DBA_ROLE_PRIVS T1
 where T1.grantee = upper(username)
 union all
 SELECT 'GRANT ' || T2.PRIVILEGE || ' TO ' || T2.GRANTEE || ';' AS TEXT
 FROM DBA_SYS_PRIVS T2
 WHERE T2.GRANTEE = upper(username)
 union all
 SELECT 'GRANT ' || T3.PRIVILEGE || ' ON ' || T3.OWNER || '.' ||
 T3.TABLE_NAME || ' TO ' || T3.GRANTEE || ';' AS TEXT
 FROM DBA_TAB_PRIVS T3
 where T3.grantee = upper(username);
 /*select privilege from dba_sys_privs where grantee in (select granted_role from dba_role_privs where grantee=upper(username) );如果有必要可-以收集角色中的权限*/
 
begin
 for v_t in v_cur loop
 begin
 dbms_output.put_line(v_t.TEXT);
 end;
 end loop;
 end;
 
最后直接运行procedure即可 execute user_priv (username => 'hr');

Adding MySQL users through the PHP web interface can use MySQLi extensions. The steps are as follows: 1. Connect to the MySQL database and use the MySQLi extension. 2. Create a user, use the CREATEUSER statement, and use the PASSWORD() function to encrypt the password. 3. Prevent SQL injection and use the mysqli_real_escape_string() function to process user input. 4. Assign permissions to new users and use the GRANT statement.
