Writing 11g
Triggers
|
 |
When people in the database
hear the word trigger ... they think of table triggers.
Event driven code that executes when an invent happens:
Either an INSERT, UPDATE, or DELETE. That isn't even half
of the story.
Triggers are not just for tables. We get into INSTEAD OF
triggers, DDL and SYSTEM EVENT triggers. And the Oracle
System Event environment variables that make them
incredibly powerful for auditing, security, and tracing.
This 3 hour hands-on workshop is only
$100/person.
|
Here's the rest of the story
- Triggers that fire when a
named columns are modified
- Triggers that fire when
someone logs into the instance
- Triggers that fire when
someone tries to truncate or drop a table
- Triggers that fire when
on granting and revoking of privileges
- The new 11g Follows
Clause
- New 11g Compound

Lab
1 |
Table
Triggers
Lab 1 is instructor led and teaches the syntax for
creating STATEMENT and ROW LEVEL BEFORE and AFTER
triggers. This hands-on session focuses on best
practices and syntax for building table triggers.
In this hands-on session we build every type of
table trigger and learn to work with the ON, OF,
and REFERENCING clauses, and cascading and
mutating triggers. The important new 11g
trigger extensions compound triggers and the
follows clause are covered in depth. |
| 7:30-8:30pm |
Lab
2 |
DDL
Event Triggers
Since version 9i Oracle has provided developers
and DBAs with a full complement of triggers that
fire when DDL statements are executed. These might
include CREATE, ALTER, TRUNCATE, DROP; or they might
fire on GRANT and REVOKE; or other DDL.
These triggers can be used for purposes of
auditing and compliance, for purposes of security,
and to prevent damage to production environments.
This hands-on session covers all of these uses. |
| 8:30-9:00pm |

System
Event Triggers
These are among the most useful of triggers for
auditing, compliance, security, monitoring, and
tracing. This instructor led session will
demonstrate how these triggers can be used. |
