The FORMAT function does not exist in the Oracle database. However, Oracle provides other relevant functions and methods to format dates, numbers, and strings.

  1. Formatting the date:
  2. TO_CHAR function: formats a date into a specified string format. For example: TO_CHAR(date_column, ‘YYYY-MM-DD’).
  3. TO_DATE function: converts a string into a date. For example: TO_DATE(‘2021-01-01’, ‘YYYY-MM-DD’).
  4. EXTRACT function: Extracts specific parts from a date, such as year, month, day, hour, minute, etc. For example: EXTRACT(YEAR FROM date_column).
  5. Number formatting:
  6. TO_CHAR function: formats numbers into the specified string format. For example: TO_CHAR(number_column, ‘999,999.99’).
  7. TO_NUMBER function: Converts a string to a number. For example: TO_NUMBER(‘123.45’).
  8. String formatting:
  9. The CONCAT function combines two strings together. For example: CONCAT(‘Hello’, ‘World’).
  10. SUBSTR function: Extracts a substring from a string. For example: SUBSTR(‘Hello World’, 7, 5).

These functions can be used to format dates, numbers, and strings according to specific requirements, in order to meet various business needs.
