I would like see ONLY the RAID ATTENDANCE – How often somebody was present in the Raids.
This would be my idea, based on your sql structure:
Write out the “Raid_ID” in the table of “* _raidplanner_character” and values this column. You write the result in a new column, e.g.: “Raid_Att” this value you are economical In terms of percentage and already we have the information.
