I have application written in Delphi 6. The application works with Local Access table. I need to know Immediately when this table has a new record (the record is being added from different application). Right now I am working with 3 seconds timer that count the records. Is there any other way to do it without this timer ?

Thanks & regards.

for short, you are limited by the database you are using

>> with oracle, you can register to get events immediately upon change
DBMS_ALERT sample:

access does not have this capability

but,
i would add a DATE/TIME Modified column

counting records will not show you the latest record modified

SELECT MAX(DT_MODIFIED) FROM TABLE

gives you the latest change time > store this and run again to check any changes
