I’m away from my databases right now, but what you need is to convert the number, which appears to be in yyyymmdd format to a date, then convert that back to character format in dd/mm/yyyy format. I suspect:
Select to_char(to_date(i_am_number, ‘yyyymmdd’), ‘dd/mm/yyyy’) from tbl_number;
That will work, and you can test it in sql*plus to be sure, however, your problem might be how you have configured Toad’s grid to display dates. So, View->Toad Options, then on the left, grid, and have a look see.
Happy Christmas.
By the way, always store dates as dates. Trust me on that matter. If you do nothing else, make sure you store data in the correct format.

Hello
Some time ago there were people who defined the dates as numbers, the column or field is already defined as a number. Now I need the format DD / MM / YYYY dates.
Thanks a lot
Morning Antoine_mc1,
My previous rep,y showed how to do it. Convert from a number in yyyymmdd format to a date with to_date, then convert that back to a char in dd/mm/yyyy format with to_char.
That’s gor fisplay if vourse, if you need to do some calculations, just convert the number to a date as described, and do what needs foing with dstes, in date data types.
HTH

Sorry, the previous reply got a little garbled!
The final paragraph should start with “That’s for display of course…” and finish with “if you need to do some calculations, just convert the number to a date as described, and do what needs doing with dates, in date data types.”
Sigh.
