Use the For Update clause on the select statement used for the stored procedure. Otherwise, it will batch your
notification rows together into a multi-record network packet.

hello Enrico,

events are sent only when the transaction is committed, that's to say
when the job is finished. To update a progress bar, follow the hint
given to me by Jason, use a selectable stored procedure and use the
SUSPEND statement.
