Is it possible to fire a trigger on an Oracle database using the .AddNew and .Update methods or do you have to use INSERT - SQL statements.

Cheers...

The trigger should fire regardless of the method used to actually insert the data. As far as the Oracle DB is concerned, data has been inserted into the table and the appropriate trigger(s) will be fired. The .AddNew and .Update methods merely provide a mechanism to handle the creation of an implicit INSERT statement.

When you call .AddNew in your VB code, Oracle will not fire any triggers.  This is because the new record is not actually added to the database until the .Update method is called.  
However, Oracle does have BEFORE INSERT and AFTER INSERT triggers that fire when .Update is called.  Since the before insert trigger is fired before the new record is added, you can use it to do any validation or anything you may have wanted to do when the .AddNew method was called.  It is also a great place to populate a PK field with a value from a sequence.
Once the record has been added to the database, the after insert trigger will fire.
