What are the different types of triggers in SQl

There are 2 types of triggers in the SQL server 2000 :-

1) INSTEAD OF triggers:

The INSTEAD OF triggers fire in place of the triggering action. For e.g., if an INSTEADOF UPDATE trigger exists on the Sales table and an UPDATE statement is executed against the Salestable, the UPDATE statement will not modify any row in the sales table. In spite, the UPDATE statement causes the INSTEAD OF UPDATE trigger to be executed, which might or might not modify the data in the Sales table.

2) AFTER triggers

The AFTER triggers execute the following in the SQL action, like insert, delete,or update. This is the traditional trigger that existed in the SQL SERVER. INSTEAD OF triggers gets executed automatically before the Primary Key & the Foreign Key constraints are checked, whereas the traditional AFTER triggers gets executed after these constraints are checked.

Unlike INSTEAD OF triggers, AFTER triggers can be created on views.
