Refresh available grid fields when table scheme has been updated

Hello folks,

In grid applications sometimes I use the “SELECT * FROM tablename” statement.

After adding/removing fields from a db table, in the past, it was possible to simply refresh the field list of a grid application by updating the query in the application’s SQL command. Then the star included also the new fields. But now this seems not to be any more possible. How can I synchronize the fields list within a grid app after changing the table scheme? In form apps, there is a specific command “Synchronize”, but not in grids.

Thanks
