Example: Querying the Number Of Weeks from the Beginning of the Quarter - Advanced SQL Engine - Teradata Database

If the current date is April 20, 2011, the following query returns 3 because April 20, 2011, is in the third week of the quarter in the Teradata calendar :

SELECT TD_SYSFNLIB.WEEKNUMBER_OF_QUARTER(CURRENT_DATE);

The following query returns 3 because April 20, 2011, is in the third week of the quarter in the ISO calendar:

SELECT TD_SYSFNLIB.WEEKNUMBER_OF_QUARTER (DATE '2011-04-20', ’ISO’);
