Formatting Dates
SQL*Plus doesn't format dates at all. If you are selecting a date column from the database, you must use Oracle's built-in TO_CHAR function to convert the date to a character string, formatting it the way you want it. As far as SQL*Plus is concerned, that makes it another character column. Table B-3 shows the date format elements that can be used with the TO_CHAR function.
