A simple max(start_time) over (partition by channel) won't work?
May be I was too laconicI 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... :-)
