如何查看某个角色被授予的权限Oracle select*fromdba_role_privs;授予用户和其他角色的角色 select*fromdba_sys_privs;授予用户和其他角色的系统权限 select*fromdba_tab_privs;数据库中对象的所有授权 参考:查看角色 权限 oracle 谷歌 DBA是用户名,是角色
如何查看某个角色被授予的权限Oracle
select * from dba_role_privs; 授予用户和其他角色的角色
select * from dba_sys_privs; 授予用户和其他角色的系统权限
select * from dba_tab_privs; 数据库中对象的所有授权
参考:查看角色 权限 oracle 谷歌
DBA是用户名,是角色名?角色名
=========================================
oracle 角色和权限的关系查看
例如:要查看 scott 具有的角色,可查询 dba_role_privs;
SQL> select * from dba_role_privs where grantee='SCOTT';
//查询 orale 中所有的系统权限,一般是dba
select * from system_privilege_map order by name;
//查询 oracle 中所有对象权限,一般是dba
select distinct privilege from dba_tab_privs;
//查询 oracle 中所有的角色,一般是dba
select * from dba_roles;
//查询数据库的表空间
select tablespace_name from dba_tablespaces;
问题 1:如何查询一个角色包括的权限?
a.一个角色包含的系统权限
select * from dba_sys_privs where grantee='角色名'
select * from dba_sya_privs where grantee='COONNECT'; connect要大写
另外也可以这样查看:
select * from role_sys_privs where role='角色名'
b.一个角色包含的对象权限
select * from dba_tab_privs where grantee='角色名'
问题 2:oracle 究竟 多少种角色?
SQL> select * from dba_roles;
问题 3:如何查看某个用户,具 什么样的角色?
select * from dba_role_privs where grantee='用户名'
显示当前用户可以访问的所有数据字典视图。
select * from dict where comments like '%grant%';
显示当前数据库的全称
select * from global_name;
其它说明
数据字典记录 oracle 数据库的所有系统信息。通过查询数据字典可以取得以
下系统信息:比如
1.对象定义情况
2.对象 占用空间大小
3.列信息
4.约束信息
...
但是因为这些个信息,可以通过 pl/sql developer工具查询得到,所以这里我
就飘过。

详解查看Oracle用户权限的七种方法
查看Oracle用户权限一般要通过一些实际操作,首先需要遍历所有用户,然后才是查看Oracle用户的权限等等操作。希望本文能给大家有所帮助。
1.查看所有用户:
<ol> <li><span><span><strong><span>select</span></strong></span><span> * </span><span><strong><span>from</span></strong></span><span> dba_users; </span></span></li> <li> <span><strong><span>select</span></strong></span><span> * </span><span><strong><span>from</span></strong></span><span> all_users; </span> </li> <li> <span><strong><span>select</span></strong></span><span> * </span><span><strong><span>from</span></strong></span><span> user_users; </span> </li> </ol>
2.查看用户或角色系统权限(直接赋值给用户或角色的系统权限):
<ol> <li><span><span><strong><span>select</span></strong></span><span> * </span><span><strong><span>from</span></strong></span><span> dba_sys_privs; </span></span></li> <li> <span><strong><span>select</span></strong></span><span> * </span><span><strong><span>from</span></strong></span><span> user_sys_privs; </span> </li> </ol>
3.查看角色(只能查看登陆用户拥有的角色)所包含的权限
<ol><li><span><span>sql></span><span><strong><span>select</span></strong></span><span> * </span><span><strong><span>from</span></strong></span><span> role_sys_privs; </span></span></li></ol>
4.查看用户对象权限:
<ol> <li><span><span><strong><span>select</span></strong></span><span> * </span><span><strong><span>from</span></strong></span><span> dba_tab_privs; </span></span></li> <li> <span><strong><span>select</span></strong></span><span> * </span><span><strong><span>from</span></strong></span><span> all_tab_privs; </span> </li> <li> <span><strong><span>select</span></strong></span><span> * </span><span><strong><span>from</span></strong></span><span> user_tab_privs; </span> </li> </ol>
5.查看所有角色:
<ol><li><span><span><strong><span>select</span></strong></span><span> * </span><span><strong><span>from</span></strong></span><span> dba_roles; </span></span></li></ol>
6.查看用户或角色所拥有的角色:
<ol> <li><span><span><strong><span>select</span></strong></span><span> * </span><span><strong><span>from</span></strong></span><span> dba_role_privs; </span></span></li> <li> <span><strong><span>select</span></strong></span><span> * </span><span><strong><span>from</span></strong></span><span> user_role_privs; </span> </li> </ol>
7.查看哪些用户有sysdba或sysoper系统权限(查询时需要相应权限)
<ol><li><span><span><strong><span>select</span></strong></span><span> * </span><span><strong><span>from</span></strong></span><span> V$PWFILE_USERS </span></span></li></ol>

MySQL processes data replication through three modes: asynchronous, semi-synchronous and group replication. 1) Asynchronous replication performance is high but data may be lost. 2) Semi-synchronous replication improves data security but increases latency. 3) Group replication supports multi-master replication and failover, suitable for high availability requirements.

The EXPLAIN statement can be used to analyze and improve SQL query performance. 1. Execute the EXPLAIN statement to view the query plan. 2. Analyze the output results, pay attention to access type, index usage and JOIN order. 3. Create or adjust indexes based on the analysis results, optimize JOIN operations, and avoid full table scanning to improve query efficiency.

Using mysqldump for logical backup and MySQLEnterpriseBackup for hot backup are effective ways to back up MySQL databases. 1. Use mysqldump to back up the database: mysqldump-uroot-pmydatabase>mydatabase_backup.sql. 2. Use MySQLEnterpriseBackup for hot backup: mysqlbackup--user=root-password=password--backup-dir=/path/to/backupbackup. When recovering, use the corresponding life

The main reasons for slow MySQL query include missing or improper use of indexes, query complexity, excessive data volume and insufficient hardware resources. Optimization suggestions include: 1. Create appropriate indexes; 2. Optimize query statements; 3. Use table partitioning technology; 4. Appropriately upgrade hardware.

MySQL view is a virtual table based on SQL query results and does not store data. 1) Views simplify complex queries, 2) Enhance data security, and 3) Maintain data consistency. Views are stored queries in databases that can be used like tables, but data is generated dynamically.

MySQL partitioning improves performance and simplifies maintenance. 1) Divide large tables into small pieces by specific criteria (such as date ranges), 2) physically divide data into independent files, 3) MySQL can focus on related partitions when querying, 4) Query optimizer can skip unrelated partitions, 5) Choosing the right partition strategy and maintaining it regularly is key.

How to grant and revoke permissions in MySQL? 1. Use the GRANT statement to grant permissions, such as GRANTALLPRIVILEGESONdatabase_name.TO'username'@'host'; 2. Use the REVOKE statement to revoke permissions, such as REVOKEALLPRIVILEGESONdatabase_name.FROM'username'@'host' to ensure timely communication of permission changes.
