In IBO you have the option to set GeneratorLinks for your inserts. At the
dataset level:

CLIENT_NUMBER=GEN_PK_ORGANIZATION

At the connection level (applies globally):

ORGANIZATION.CLIENT_NUMBER=GEN_PK_ORGANIZATION

By this means, IBO will get the sequence number during the BeforeInsert
event and it will be available to the application before anything is posted
to the database.

Btw, EDatabaseError is a client-side exception, thrown on the basis of the
application's knowledge of the metadata. Exceptions returned from the
server are EIB_IscError and EIBO_IscError descendants, respectively.
