Get last full 20 weeks with function ADD_MONTHS(date - EXTRACT(day FROM date) +0, 0) - response (4) by Nexsn

Hab mich nicht getraut auf deutsch zu schreiben weil ja englisches Forum :) - deshalb auch Englisch weiter.
thanks again for your help! at this time, I'm not into this database-thinking, I hope it will become better ;)
 
query works! for testing I replaced test-dates instead of current_date.
there is only 1 little problem i can fix on my own: i get the sunday before the first monday, i guess because the english time-calulation.
But it should be fixed easy with +1 .
danke nochmal und schönen tag :)
LG
