一、需求
订单销量数据统计，按商品分类（二级，三级）或商品统计，平均采购单价，毛利单价，毛利金额，毛利率等
销量 = 商品销售数量
平均采购单价 = 采购订单总金额/采购订单总数量
毛利单价 = 销售单价-采购单价
毛利金额 = 毛利单价*销售数量
毛利率 = 毛利单价/销售单价
二、实现
组织架构说明：总运营中心-子运营中心-服务仓（服务仓下订单，进行采买）
涉及到两个主表的查询，订单表和流水表（商品入库类型）的查询
第一步：查询时间范围内订单，并以时间和商品code分组
第二步：查询时间范围内流水表商品平均入库价格（一个服务仓下的最近一次入库（时间可选）商品价格，以商品分组得到平均入库价格）
第三步：以左边表订单商品左查找右边表商品入库价格
第一轮查询sql，数据量大了，效率很低

优化点：如何取服务仓的商品最近一次流水记录sql效率更高
( SELECT t1.stockPrice FROM tims_stock_flow t4 WHERE t4.whouseGuid = t1.whouseGuid AND t4.basePdtCode = t1.basePdtCode AND t1.flowTime < '2022-06-01 23:59:59 999 '
ORDER BY t4.serialNo DESC LIMIT 1 ) AS lastStockPrice,
以 whouseGuid, basePdtCode分组结果desc排序后GROUP_CONCAT stockPrice 字段取第一条stockPrice
SELECT SUBSTRING_INDEX( GROUP_CONCAT( t1.stockPrice ORDER BY t1.serialNo DESC ), ',', 1 ) lastStockPrice,
因为流水记录表数据量非常大，嵌套查询流水表，效率很低。以whouseGuid，basePdtCode 分组后利用函数GROUP_CONCAT 并排序，可以让想要的数据在第一条并截取，避免了嵌套查询。
