Displaying a Date in a Specific Format Previously, all Oracle date values were displayed in the DD-MON-YY format. The TO_CHAR function allows you to convert a date from this default fomat to one specified by you. Guidelines
? The format model must be enclosed in single quotation marks and is case sensitive;
? The format model can include any valid date format element. Be sure to separate the date value from the format model by a comma.
? The names of days and months in the output are automatically padded with blanks.
? To remove padded blanks or to suppress leading zeros, use the fill mode fm element.
? Yon can resize the display width of the resulting character field with the SQL*Plus COLUMN command.
? The resultant column width is 80 characters by default.
