Delphi Programming question

Hi,

My problem is that I've got a database with SQL trigger.
So, when I add a new record to the database, the new record
can't be seen in the DBGRID comp. linked to that database.
When I refresh  the database, then the new record can be see. The question is is there any chance to see the newly
added record without freshing the whole database?
Imagine the database contains 50.000 record. It lasts a lot
of time for refreshing.
So can be refreshed only the new record or not?

1. Use the TQuery component to populate the DBGrid (instead of TTable). Have an SQL statement for populating the DBGrid.

2. To refresh the DBGrid, you have to call the close and open methods of the TQuery component. Ex:
QueryInvoice.close; QueryInvoice.open;

3. You can do this periodically by using a timer control. In fact security trading systems use this methodology to keep screens
upto date. Of course, if you are using MS SQL Server, you could
use an ODS service which would send a message to the Delphi program to close and open the TQuery component.
