<p>I've been hearing about triggers, and I have a few questions.<br />
What are triggers?<br />
How do I set them up?<br />
Are there any precautions, aside from typical SQL stuff, that should be taken?</p>

A trigger is a named database object that is associated with a table and that is activated when a particular event occurs for the table.
To create a trigger:
```
```
CREATE TRIGGER triggerName [BEFORE|AFTER] [INSERT|UPDATE|DELETE|REPLACE] ON tableName FOR EACH ROW SET stuffToDoHERE;
```
```
Even though I answered this part the other question still stands.
