EXAMPLE - DATE and TIME Functions

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.

Transform:

derive type:single value: DATEFORMAT(DATE (year, month, day),'yyyy-MM-dd') as:'fctn_date'

derive type:single value: DATEFORMAT(TIME (hour, minute, second),'HH-mm-ss') as:'fctn_time'

derive type:single value: DATEFORMAT(DATETIME (year, month, day, hour, minute, second),'yyyy-MM-dd-HH:mm:ss') as:'fctn_datetime'


Results:

NOTE: All inputs must be inferred as Integer type and must be valid values for the specified input. For example, month values must be integers between 1 and 12, inclusive.

You can apply other date and time functions to the generated columns. For an example, see YEAR Function.
