That shouldn't be the case. Dates should never be stored as strings. You need to change that or you'll run into other problems down the line too, as well as its being generally inefficient

As I mentioned above you need to sort the data once it is loaded, and not using a query.

You can use the code you already have to create a Comparator for use with the sort.

You can get a flavour of how it should be by doing something like the following. Of course it's less efficient than storing your dates properly as i mentioned above, but still more efficient than sorting it twice, the second time in Java:

                       
                                String sql = "select TO_DATE(a.date, 'DD/MM/YYYY'),b.name,a.purpose,a.status,a.emid,c.time from room_booking a, room b, time_slot c where a.rid = b.rid and a.rbid=c.rbid and status = 'Taken' order by 1";

Yes, it might be too late now if you have clients that are treating the date as a string. If so, leave it along and try the query as i just posted

Try the following. You need to get the DBAs on to it

                       
                                String sql = "select TO_DATE(CONCAT (a.date, ' 00:00:00')),b.name,a.purpose,a.status,a.emid,c.time from room_booking a, room b, time_slot c where a.rid = b.rid and a.rbid=c.rbid and status = 'Taken' order by 1";
