Are you filling in the Insert, Update, Delete SQL properties yourself or are
you letting the IB_Query do it for you at run-time? It looks to me like the
field may not be part of the insert query so it is therefore being seen as
NULL on the server.

Object methods all have a Sender parameter which is the object executing the
method. For BeforeInsert and AfterInsert methods, the Dataset object that is
passed is what you should use in the statements, not the actual component
name IB_QueryConta.
