需求1：滚动计算10月每天 当天至+25天 范围内 总配货门店数和箱数
- 基础表：对底表聚合去重，将日期转为日期格式
sql
-- 天商品仓库 门店配货表
DROP TABLE IF EXISTS h_tmp.tmp_base ;
CREATE TABLE h_tmp.tmp_base AS
SELECT
TO_DATE(order_time) as dt
,h_code -- 商品编码
,wrh_name -- 仓库名称
,shop_code -- 配货门店
,sum(stock_box) as inflow_qty -- 配货箱数
FROM base
WHERE dt =DATE_SUB(CURRENT_DATE,1))
AND is_send=1
AND DATE_FORMAT(order_time,'yyyy-MM-dd') BETWEEN '2025-10-01' AND '2025-10-31'
GROUP BY TO_DATE(order_time),wrh_name,shop_code,h_code
;
-- 取10-01的数，方便后面验证
SELECT COUNT(DISTINCT shop_code) as shop_cnt
,SUM(inflow_qty) as inflow_qty
FROM h_tmp.tmp_dw_inflow_di_251117
WHERE dt BETWEEN '2025-10-01' AND '2025-10-26'
AND h_code = '123456'
AND wrh_name = '上海仓'-
滚动求和
- 窗口版 使用 range 限制范围
PRECEDING 之前
FOLLOWING 之后 - 自连接版 限制连接表日期范围
- 窗口版 使用 range 限制范围
