Hi, I've a field that contain values-comma-separated like A) 1;2;3;;5 -- ;2;;4;5 but also B) 12;34;18 how I can get the max value? For A I tried: SELECT max(array_upper(string_to_array(answer,';'),1)) FROM values; and work fine, but for B case I don't find a solution like SELECT max(string_to_array(answer,';')) FROM values;
Any ideas?
