DATE '2006-05-20' + INTERVAL 5 DAY -> DATE '2006-05-25' DATE '2006-05-20' + INTERVAL 5 MONTH -> DATE '2006-10-20' DATE '2006-05-20' + INTERVAL 5 YEAR -> DATE '2011-05-20'
schema:gisq
In this example we show the date 7 days after the value specified in whn
SELECT whn, DATE(whn) + 7 FROM eclipse
SELECT whn, DATE(whn) + 7 FROM eclipse
SELECT whn, whn + DATE(7 DAY) FROM eclipse
SELECT whn, whn + 7 FROM eclipse
SELECT whn, whn+INTERVAL 7 DAY FROM eclipse
