May be I was too laconic
I have thought about getting only value of rows, of which one particular
value is max for the whole group - so I am not interested in rows which
have this particular value less than max. "A simple max(start_time) over
(partition by channel)" gives me all rows while I need only those which
start_time=max(start_time) over (partition by channel). Solutions I have
provided gives me exactly what I need, however I try to find more of
them, then compare them and choose one... :-)
