Currently i have date in the
2006/01/01 00:00:00
What should i use to convert it into following format
01-JAN-2006.
if it's a string use
to_char(to_date('2006/01/01 00:00:00', 'YYYY/MM/DD HH24:MI:SS'), 'DD-MON-YYYY')
If it's a DATE use
to_char(date_val, 'DD-MON-YYYY')
BUT whether you'll get JAN or national abbr of January depends on your NLS settings (session and database)
