Create a string representing a date to a particular format The Standard provides us with the EXTRACT function that can be used however many engines provide a more convenient alternative.

EXTRACT EXRESSION as: EXTRACT(MONTH FROM wk) other components that may be extracted:

   YEAR
   MONTH
   DAY
   HOUR
   MINUTE

In this example we use CAST in order to build up a date in the UK format dd/mm/yyyy
