Merging multiple rows with same field in column

Question

I am making a leaderboard for a game server and would like a hand with something.

I have a table in MySQL that looks like this (There are other columns that exist but I want to ignore)

Is there a way to combine each row with the same value in steam_id_64 , but with player_name show the last used steam name (Or current from steam) and is it possible to hide the row where steam_id_64 is BOT ?

I have php5 if that is helpful. Thank you for the help.

Answer 1

使用!=隐藏Steam_id_64为BOT的行

Select * from table where steam_id_64 !='BOT'

Answer 2

You have to sum up the different columns using sum() function. To avoid those bot entries you can use a condition to test for player_name is not BOT

select
  player_name,
  sum(kills) as kills,
  sum(deaths) as deaths,
  sum(assists) as assists,
  sum(head_shots) as headshots,
  sum(team_kills) as team_kills,
  sum(assists_team_attack) as assist_team_attack,
  sum(damage) as damage,
  sum(hits) as hits,
  sum(shots) as shots,
  sum(last_alive) as last_alive
group by steam_id_64
where steam_id_64 != "BOT"

To make later handling convenient I have added "... as field_name" to each sum().

Please try this and refine your question if something is missing.
