How to format and sort a date in Oracle?

Question

In my application am trying to format and sort the date, i am using to_char() function to format the date to my required format, but when i sort them it is sorting

Answer 1

The easiest way is to retrieve the same field with the query again and doing sorting based upon that filed

In your example

SELECT 
         to_char( your_date_column, your_format_mask ) as formate_purpose,
         your_date_column as sorting_purpose
FROM your_table

ORDER BY your_date_column
