Using the Tdataset.post method in BDE causes the program to lose current

Hello.

I'm using Delphi 6 and BDE to work against an Oracle or SQL server database (native connection).

During the application, I'm running a select statement that does not return a value in order to create an empty dataset. After filling some data in the recordset I use the post method to save the record. The problem is that after doing the post method, I lose the current record and have an empty dataset, which requires me to re-query the table to retrieve the current record.

Any idea how to solve this problem?

Thanks.

use cachedupdates

in the post-event use the a code like

begin
  try
    Dataset.ApplyUpdates;
    Dataset.CommitUpdates;
  except
    Dataset.CancelUpdates;
    raise;
  end;
end;

or just close and reopen your query instead of cachedupdates

meikl,

The problem is that if I reopen my query, it means that I'm going to the database
again, which is exactly what I want to prevent.

Will using cached updates make me stay on the current record?
