Question

我有一个查询，返回过去7天的每日数据。我想知道使用bigquery

获取过去4周每周数据的语法

- 周总计

第1周15 第2周20 第3周35

Answer 1

沿着这些方向：

SELECT 
  YEAR(day) AS year, 
  WEEK(day) AS week, 
  SUM(metric) AS total 
FROM YourTable
WHERE WEEK(CURRENT_DATE()) - WEEK(day) < 4
GROUP BY 1, 2

要测试/播放 - 您可以使用以下方法，希望模仿您的数据

SELECT 
  YEAR(day) AS year, 
  WEEK(day) AS week, 
  SUM(metric) AS total 
FROM (
  SELECT 
    DATE(DATE_ADD(TIMESTAMP('2016-01-01'), pos - 1, "DAY")) AS day, 
    CAST(100 * RAND() AS INTEGER) AS metric
  FROM (
       SELECT ROW_NUMBER() OVER() AS pos, *
       FROM (FLATTEN((
       SELECT SPLIT(RPAD('', 1 + DATEDIFF(TIMESTAMP(CURRENT_DATE()), TIMESTAMP('2016-01-01')), '.'),'') AS h
       FROM (SELECT NULL)),h
  )))
) AS YourTable
WHERE WEEK(CURRENT_DATE()) - WEEK(day) < 4
GROUP BY 1, 2
