    1,个人开户报表统计

    优化前语句,执行时间80多秒

    SELECT
    	a.DA AS f_da,
    	a.account_name AS f_account_name,
    	a.sex AS f_sex,
    	a.nick_name AS f_nickname,
    	a.create_time AS f_open_account_time,
    	DATE_FORMAT(a.create_time, '%Y%m%d') AS f_open_account_date,
    	HOUR (a.create_time) AS f_open_account_hour,
    	a.group_ids AS f_group_id,
    	a.f_reg_source AS f_reg_source,
    	t.f_user_area_id AS f_user_area_id,

    		LEFT JOIN (

    			FROM
    				account_token b
    			GROUP BY

    		) token ON a.DA = token.DA
    	)
    WHERE
    	a.create_time > '20000101'
    AND a.create_time < '20000102'
    
    

    优化后语句,执行2S

    EXPLAIN
    SELECT SQL_NO_CACHE
    	a.DA AS f_da,
    	a.account_name AS f_account_name,
    	a.sex AS f_sex,
    	a.nick_name AS f_nickname,
    	a.create_time AS f_open_account_time,
    	a.home_id AS f_home_id,
    	DATE_FORMAT(a.create_time, '%Y%m%d') AS f_open_account_date,
    	HOUR (a.create_time) AS f_open_account_hour,
    	a.group_ids AS f_group_id,

    	CONCAT_WS(
    		",",

    		d.f_pid_id,

    	min(b.f_first_login_time) as min_f_first_login_time,
    	DATE_FORMAT(

    	) AS f_first_login_date,
    	HOUR (b.f_first_login_time) AS f_first_longin_hour,
    	b.f_app_version AS f_app_version
    FROM
    	((account_info a
    LEFT JOIN t_da_boss_info t ON a.DA = t.f_da)
    LEFT JOIN (
    	SELECT
    		home_id,
    		GROUP_CONCAT(device_id) AS device_id,
    		GROUP_CONCAT(cai_id) AS f_cai_id,
    		GROUP_CONCAT(mobile_id) AS f_mobile_id,

    		device_info
    	GROUP BY
    		home_id
    )
    d ON a.home_id = d.home_id)
    LEFT JOIN (
    	SELECT
    		DA,
    		f_extend,
    		f_extend AS f_app_version,
    		f_create_time AS f_first_login_time
    		FROM
    		account_token
    ) b ON a.DA = b.DA
    WHERE
    	a.create_time BETWEEN '2000-01-01 00:00:00'
    AND '2000-01-02 00:00:00'  GROUP BY a.da;
    
    

    account_token表改为走主键DA,DA字段有主键,join走主键,速度很快
