automatically refreshing of a table

Hello Vaadin DB binding experts

I have a table that is connected to a database using a code like this


                String sql = ".....";
		FreeformQuery q1 = new FreeformQuery(sql, 
					DbAf.getInstance().getConnectionPool(),
					DbTablePostings.FIELD_id);
	        m_container = new SQLContainer (q1); 
	        setContainerDataSource(m_container);

I would like to know if it is possible for the table to show automatically the new records that fit inside the query resuts.
Is it possible for table to refresh autocatially and show the new database records?

They told me that this is possible, even though I can’t imagine how this could be done.

Any hints?

Best regards
