题解 | 深入分析各款产品年总销售额与竞品的年度对比

描述

【背景】：OPPO 公司为了精准评估产品在 2023 年的市场表现，需要根据以下三个数据表，深入分析各款产品年总销售额与竞品的年度对比。

【原始表】：

oppo_products_detail（OPPO 产品详情）表:

product_id (产品 ID): 产品的唯一标识符
product_name (产品名称): 产品的名称
product_category (产品类别): 固定的（智能手机、平板电脑、智能手表）

sales_info（销售信息）表:

sale_id (销售 ID): 销售的唯一标识符
product_id (产品 ID): 所属产品的唯一标识符，用于关联 OPPO 产品详情表中的产品
sales_channel (销售渠道): 固定的（线上、线下）
region (地区): 产品销售的地区
quarter_1_sales_amount (第一季度销售额): 产品在该地区、该销售渠道的第一季度销售额
quarter_2_sales_amount (第二季度销售额): 产品在该地区、该销售渠道的第二季度销售额
quarter_3_sales_amount (第三季度销售额): 产品在该地区、该销售渠道的第三季度销售额
quarter_4_sales_amount (第四季度销售额): 产品在该地区、该销售渠道的第四季度销售额

competitor_analysis（竞品）表:

analysis_id (分析 ID): 竞品的唯一标识符
product_id (产品 ID): 对应的 OPPO 产品的唯一标识符，用于关联 OPPO 产品详情表中的产品
competitor_name (竞品名称): 竞品的名称
total_competitor_sales_amount_2023 (竞品 2023 年全年销售总金额): 竞品 2023 年全年的销售总金额

【要求】：根据上述表格，查询每个产品在不同地区、不同销售渠道下 2023 年的全年销售总额，以及与主要竞品 2023 年全年销售总金额的差值。结果按照产品 ID 升序排列。要求查询出来的表格的字段如下：

product_id (产品 ID): 对应的 OPPO 产品的唯一标识符，用于关联 OPPO 产品详情表中的产品
product_name (产品名称): 产品的名称
competitor_name (竞品名称): 竞品的名称
total_sales_amount_of_product（产品全年4个季度，全销售渠道的销售总金额）: 产品 2023 年全年的销售总金额
sales_difference_with_competitor（产品和竞品的销售差值）：2023年产品和竞品的销售差值

【示例】

oppo_products_detail（OPPO 产品详情）表:

sales_info（销售信息）表:

competitor_analysis（竞品）表:

【按照要求查询出来的表】

【解释】

按照上述示例中的数据，产品ID是1的产品全年总销售额 = 10000+15000+12000+18000+6000+20000+8000+10000 = 99000，竞品的销售总金额是80000，差值是19000
