Example: Querying the Number of Months from the Year Beginning - Analytics Database - Teradata Vantage

If the current date is March 15, 2011, the following query returns 3 because March 15, 2011, is in the third month of the Teradata calendar:

SELECT TD_SYSFNLIB.MONTHNUMBER_OF_YEAR(CURRENT_DATE);

The following query returns 3 because March 15, 2011, is in the third month of the ISO calendar:

SELECT TD_SYSFNLIB.MONTHNUMBER_OF_YEAR(DATE '2011-03-15', ’ISO’);
