Example: Querying the Number of Quarters from the Year Beginning - Teradata Vantage

If the current date is December 20, 2010, the following query returns 4 because December 20, 2010, is in the fourth quarter in the Teradata calendar:

SELECT TD_SYSFNLIB.QUARTERNUMBER_OF_YEAR(CURRENT_DATE);

The following query returns 4 because December 10, 2010, is in the fourth quarter in the ISO calendar:
