FAQ: TRUNC in Oracle

• What’s the difference between TRUNC and ROUND in Oracle?
  TRUNC removes digits or date parts without rounding; ROUND performs rounding to the nearest specified unit.

• Can I truncate a TIMESTAMP in Oracle?
  Yes, but precision may be limited. For timestamps, you can usually truncate to 'DAY', 'MONTH', or 'YEAR'.

• Is the format parameter required?
  No, it is optional. By default, TRUNC(date) removes the time portion, returning midnight for that date.
