我有一个数据库,其中有一个用户表,他们想奖励记录表多少次,我想这样得到(WEEK WISE)
user_name user_week user_reward
abc 24,25,26 4,5,6
我的查询是这样的
SELECT WEEK(cpd.added_date),COUNT(cpd.result)
FROM cron_players_data cpd WHERE cpd.player_id = 81
AND cpd.result = 2 AND cpd.status = 1
GROUP BY WEEK(cpd.added_date);
结果是
user_name user_week user_reward
abc 24 4
abc 24 5
abc 24 6
我使用group_concat与count,但它没有用,是否有任何替代方法可用于此期望结果
最佳答案
您有两个级别的分组,第一个星期,然后是用户名,
因此,我建议您对第一个分组使用子查询,例如:
SELECT
user_name,
GROUP_CONCAT(user_week) AS user_weeks,
GROUP_CONCAT(user_reward) AS user_rewards
FROM (
SELECT
user_name,
WEEK(cpd.added_date) AS user_week,
COUNT(cpd.result) AS user_reward
FROM cron_players_data AS cpd
WHERE
cpd.player_id = 81 AND
cpd.result = 2 AND
cpd.status = 1
GROUP BY user_week
) as temp
GROUP BY user_name;
