triggers - 创建一个监听多个表的全局触发器

Question

我想在 Oracle 11g 中创建一个全局触发器。可用于审计大约 100 个表。多个表可以触发单个触发器。如果是，那么我怎样才能做到这一点？

Answer 1

I want to create a global trigger in oracle 11g ,which can be used for auditing of around 100 tables

你有什么理由想重新发明轮子吗？为什么不利用 Oracle 的内置审计？

Oracle Base提供有关如何开始审计的一些基本信息:

Auditing can enabled by setting the AUDIT_TRAIL static parameter, which has the following allowed values.

AUDIT_TRAIL = { none | os | db | db,extended | xml | xml,extended }

以下列表提供了每个设置的说明:

none or false - Auditing is disabled.
db or true - Auditing is enabled, with all audit records stored in the database audit trial (SYS.AUD$).
db,extended - As db, but the SQL_BIND and SQL_TEXT columns are also populated.
xml- Auditing is enabled, with all audit records stored as XML format OS files.
xml,extended - As xml, but the SQL_BIND and SQL_TEXT columns are also populated.
os- Auditing is enabled, with all audit records directed to the operating system's audit trail.

启用审计到数据库审计跟踪启用审计到数据库

SQL> ALTER SYSTEM SET audit_trail=db,extended SCOPE=SPFILE;

System altered.

关闭并重新启动数据库

SQL> SHUTDOWN
Database closed.
Database dismounted.
ORACLE instance shut down.
SQL> STARTUP
ORACLE instance started.

现在审核 SELECTS , INSERTS , UPDATES , DELETES来自用户 cube做这个:

CONNECT sys/password AS SYSDBA

AUDIT ALL BY cube BY ACCESS;
AUDIT SELECT TABLE, UPDATE TABLE, INSERT TABLE, DELETE TABLE BY cube BY ACCESS;

可以通过查询 DBA_AUDIT_TRAIL 调出审计日志。
