If you want to select something from your database, then use Query component and SQL language. This example shows, how to select all records, where "Boa" value is in the "NAME" field.
procedure TForm1.Button1Click(Sender: TObject); begin with Query1 do begin Active:=False; SQL.Clear; SQL.Add('Select * from animals where name="Boa"'); Active:=True; end; end;
