谷歌大查询计数

我试图在谷歌BigQuery的过去3个月内拉下所有客户少于4个订单。谷歌大查询计数

SELECT a.user_id, b.refer_by, FROM water_db.tb_order a INNER JOIN 
    water_auth.tb_users b ON a.user_id = b.user_id WHERE ( SELECT 
    user_id FROM 
    water_db.tb_order GROUP BY 
    user_id HAVING 
    COUNT(DISTINCT(a.user_id <= 4))) AND status = 3 AND DATE(a.order_date) >= 
    '2017-02-15' AND DATE(a.order_date) <= '2017-05-15';------

我猜每个记录添加到它相当于一个订单，但像一些表时间：

SELECT 
a.userid, b.refer_by 
FROM water_db.tb_order a 
INNER JOIN water_auth.tb_users b ON a.user_id = b.user_id 
WHERE 
(COUNT(userid) < 4) 
and 
DATE_ADD(MONTH, -4, a.order_date)

日期的功能可能会有所不同，因为我不是100％确定Google Big Query中的内容

我认为最好的方法是从用户表中进行选择，因此您不需要重复删除ID，只需将条件表达为WHERE子句的一部分即可。这应该有助于开始：

#standardSQL 
SELECT 
    user_id, 
    refer_by 
FROM water_db.tb_users 
WHERE (
    SELECT COUNT(*) 
    FROM water_db.tb_order 
    WHERE tb_users.user_id = tb_order.user_id AND 
    status = 3 AND 
    DATE(order_date) BETWEEN '2017-02-15' AND '2017-05-15' 
) <= 4;

在此查询中，联接表示为涉及两个表的相关子查询。您可以使用此查询使用示例数据来尝试：

#standardSQL 
WITH tb_users AS (
    SELECT 1 AS user_id, '[email protected]' AS refer_by UNION ALL 
    SELECT 2, '[email protected]' UNION ALL 
    SELECT 3, '[email protected]' 
), 
tb_order AS (
    SELECT 1 AS user_id, TIMESTAMP '2017-04-12' AS order_date, 3 AS status UNION ALL 
    SELECT 2, TIMESTAMP '2017-05-03', 3 UNION ALL 
    SELECT 1, TIMESTAMP '2017-03-13', 3 UNION ALL 
    SELECT 1, TIMESTAMP '2017-02-28', 3 UNION ALL 
    SELECT 2, TIMESTAMP '2017-05-06', 3 UNION ALL 
    SELECT 1, TIMESTAMP '2017-05-01', 3 UNION ALL 
    SELECT 1, TIMESTAMP '2017-05-02', 3 
) 
SELECT 
    user_id, 
    refer_by 
FROM tb_users 
WHERE (
    SELECT COUNT(*) 
    FROM tb_order 
    WHERE tb_users.user_id = tb_order.user_id AND 
    status = 3 AND 
    DATE(order_date) BETWEEN 
     '2017-02-15' AND '2017-05-15' 
) <= 4;
