Subject Re: [IBO] Primary Key of Query set by Trigger
Author Svein Erling Tysvær
The primary key is the identifier of a row - and unless IBO knows this
identifier (or some other unique fields) it is simply impossible for the
client to identify the row in question.

You simply cannot put something into the server and try to get it back
unless you know what it is. It's like looking into a telephone directory
for the phone number of a person you have forgotten the name of.
