I don’t really get the point of this because the whole idea of using triggers is to automatically have the database do something without the need to do it from your server-side language on every insert/update or delete.

So basically it’s code you only execute once to create the trigger.

I suppose it’s just creating a trigger between your <CFQUERY> tags similar to how you do an insert, update or delete operation

Before the insert

CREATE TRIGGER triggerName BEFORE INSERT ON tableName FOR EACH ROW what_ever_you_want_your_trigger_todo;

After the insert

CREATE TRIGGER triggerName AFTER INSERT ON tableName FOR EACH ROW what_ever_you_want_your_trigger_todo;

But really I would do this using a mysql-client, set and forget it. Depending on the use of BEFORE or AFTER it will be executed either before or after your insert/update/delete statement on that table.
