.net - How will you process date values stored in varchar fields? -

-

your user wants report sorted date. report being created using c# , odp.net sort on date column , output not user expected.

upon closer inspection, find date column varchar2 field. values in column stored in dd-mon-yy "01-jan-10" format.

how sorted date?

my answer: 

select to_date(fakedatecolumn,'dd-mon-yy') table order to_date(fakedatecolumn,'dd-mon-yy')

is there available in front-end? suppose datetime.parseexact trick well.

you answer correct. sorting should done @ database level. using datetime.parseexact mean rows need fetched @ client , sorted might not efficient. once results fetched sorted database parse string datetime show formatted in user interface.
