HELLO, I want to make a query in ORACLE that brings me all the scores that are lower than 3.0 (YELLOW) but not of those that have the same DERA_FKREGISTROACTIVIDAD and in some have a score higher than 3.0, the blues have a score less than 3 but there is another DERA_FKREGISTROACTIVIDAD that has a score much higher than 3.0
that is to say, to bring the records in which they do not allan past and those that if not consult them
IN ADVANCE THANK YOU.
