我试图将3个表的输出合并为一个查询。
以下是表格结构
player_id int(10)
league_id int(10)
player_name varchar(150)
性别tinyint(3)
initial_hc smallint(6)
total_score int(10)
total_games smallint(6)
current_hc smallint(6)
league_player tinyint(3)
series_id int(10) player_id int(10) point smallint(6)
series_id int(10)
player_id int(10)
rankint(6)
last_game smallint(6)
true_score smallint(6)
障碍小(6)
total_score smallint(6)
这是我的2个内部连接语句..它们看起来几乎相同......但是我找不到一种方法来组合它,以便第一个sql将返回附加列,即BL_LEAGUES_RANK中的总和(rn.total_score)
SELECT pl.player_id, pl.player_name, pl.gender, pl.league_player, SUM( pt.point ) AS total_points FROM `bl_players` pl INNER JOIN `bl_points` pt ON pl.player_id = pt.player_id AND series_id =1 GROUP BY player_id ORDER BY total_points DESC
SELECT pl.player_id, pl.player_name, pl.gender, pl.league_player, SUM(rn.total_score) as total_pinfall FROM `bl_players` pl INNER JOIN `bl_leagues_rank` rn ON pl.player_id = rn.player_id AND series_id =1 GROUP BY player_id ORDER BY total_pinfall DESC
甚至可能吗?提前感谢您对此的任何意见...
答案 0 :(得分:0)
我认为这应该有用......
SELECT pl.player_id, pl.player_name, pl.gender,
pl.league_player, SUM( pt.point ) AS total_points
FROM bl_players pl, bl_points pt, bl_leagues_rank rn
WHERE pl.player_id = pt.player_id AND series_id =1
AND pl.player_id = rn.player_id
GROUP BY player_id ORDER BY total_points DESC
