This example illustrates how the DATE and TIME functions operate. Both functions require that their outputs be formatted properly using the DATEFORMAT function.

  • DATE - Generates valid Datetime values from three integer inputs: year, month, and day. See DATE Function.
  • TIME - Generates valid Datetime values from three integer inputs: hour, minute, and second. See TIME Function.
  • DATETIME - Generates valid Datetime values from six integer inputs: year, month, day, hour, minute, and second. See DATETIME Function.
  • DATEFORMAT - Formats valid Datetime values according to the provided formatting string. See DATEFORMAT Function.
