登入用戶，訂購用戶，活躍用戶，留存用戶

1、登入用戶，訂購用戶，資源訪問用戶

    SELECT 
        P.d,P.user_c,Q.pay_c,R.res_c
    FROM 
    (
        SELECT 
            DATE_FORMAT(create_date,'%Y-%m') AS d,
            COUNT(DISTINCT(userid)) AS user_c
        FROM user_table 
        WHERE create_date LIKE '2019-11%'
             AND product_key = "product_key1"
        GROUP BY d
    ) P
    LEFT JOIN
    (
        SELECT 
            DATE_FORMAT(create_time,'%Y-%m') AS d, 
            COUNT(DISTINCT userid) AS pay_c
        FROM
            order  
        WHERE  status = 1 
                AND create_time like '2019-11%' 
                AND product_key = "product_key1"
        GROUP BY d
    ) Q
    ON P.d = Q.d
    LEFT JOIN 
    (
        SELECT 
            DATE_FORMAT(create_date,'%Y-%m') AS d,
            COUNT(DISTINCT(userid)) AS res_c
        FROM pv.userres
        WHERE create_date LIKE '2019-11%'
            AND product_key = "product_key1"
        GROUP BY d
    ) R
    ON Q.d = R.d

2、某段時間留存用戶UV，訂購UV，資源訪問UV，活躍UV，沉默UV

   SELECT 
        "2019-8-01 ~ now" AS month_range,
        COUNT(DISTINCT userid) AS c_login_user,
        COUNT(DISTINCT pay_userid) AS c_pay_userid,
        COUNT(DISTINCT res_userid) AS c_res_userid,
        COUNT(DISTINCT activate_userid) AS c_activate_userid,
        COUNT(DISTINCT silence_user) AS c_silence_user
    FROM(
        SELECT 
            userid,

            (CASE WHEN  -- 最近三個月活躍用戶數，登入天數>20
                    (
                     SELECT 
                         count(DISTINCT create_date,t3.userid )

            (CASE WHEN  -- 最近某段時間沉默用戶數，沒有訪問記錄
                NOT EXISTS(
