Alerter On Firebird

Post by alienjohn » Wed 12 May 2021 22:58

Hello,

Reading the topic viewtopic.php?f=3&t=35319&p=122653&hili ... er#p122653
i notice that :

"a) in Delphi i can get connectionID and verify, that executed by itself, so i can skip double refresh"

I try to use Alerter to refresh data from other user/users, is there a way to know if the Alerter is called localy or from other user, to avoid double refreshs?

Thanks
John

Hey John,

Please note that the post you refer to was related to PostgreSQL but not InterBase/Firebird.
Can you kindly specify to which DBMS your request is related to?

Thanks in advance,
Viktor

Hi John,

Please note that the post you refer to is related to PostgreSQL but not InterBase/Firebird.
Interbase/Firebird does not support functionality available in PostgreSQL. In InterBase/Firebird events are simple notification and don’t carry any additional data beside the event name itself. They do carry a “count” - in case many events of same type happen at once, the count shows how many were there.

Best regards,
Viktor
