After updating dataset the record goes to the end of the dataset

Hi all,<br /><br />I am using Postgres in a Delphi application through ODBC. I am having an issue with updating
records.<br/><br />When I create a dataset to get the records in a table then after I update one of these records and
thenrefresh the dataset, the record goes to the end of the dataset. This is disappointing when editing records on a
DBGrid,where users find their updated records jump to the end of the grid. Even after restarting the application, the
updatedrecord keeps showing at the end of the grid. I have tried the same thing with SQL Server and it works normally,
soI thought it was a postgres behvior.<br /><br />Has anyone an idea about what could be the cause of such a
behavior.<br/><br />Thanks to all in advance.<br /><br />Nacef<br />
