I have tried to find a few answers on this but nothing has come up - is there a way to take a time column (00:02:01) and SUM ALL the values for the total Hours? I have tried SUM(HOUR('TALK TIME'
)) but that is not giving me the correct summarized number of hours. I also tried to do in the ETL but the column keeps coming up as blank. Is there an easier way or another article I can reference?
