In this example, an OFF and an ON exception are defined for the Teradata business calendar and the information about them is added to the DBC.BusinessCalendarException table. Days with the OFF status are non-business days. Days with the ON status are business days.
EXEC DBC.CreateException
('Teradata', ’OFF’, DATE '2008-03-03', 'Holiday');
EXEC DBC.CreateException
('Teradata', ’ON’, DATE '2008-06-07', 'Holiday make up day');
The two exceptions are inserted into the Teradata business calendar. This first exception indicates that March 3, 2008 is now a non-business day (noted in the comment as a holiday). The second exception indicates that June 7, 2008 is now a business day (noted in the comment as a day to make up for a previous holiday).
The CalendarPeriod of the Teradata calendar is from January 1, 1900 to December 31, 2100. If you try to insert holidays beyond the CalendarPeriod boundary, the insertion is aborted.
