我可能错误地问了这个问题，但我有以下查询，我试图为给定商店提取 3 个不同的指标。当我拉它们时，结果如下：

有没有一种方法可以获得所有这些，以便生成、发布和每日百分比都在一条线上？我希望它看起来像这样

这是我使用的查询：

SELECT

只需SUM(..)在每个 CASE WHEN 周围添加一个，然后添加一个GROUP BY STORE_NUM, REPORT_STARTDATEafterq

ps; 你不需要ELSE 0- 如果你省略它，那么当前承载 0 的行将改为 NULL；NULL 不参与聚合，因此当 group by 执行“将 3 行压缩为 1”的工作时，使用 MAX 而不是 SUM 可以更容易地“获取列中唯一的非空值”

因此，对于未来，我推荐更通用的模式：

SELECT 
  x, y,
  MAX(CASE WHEN ... THEN ... END) as ... --do not use ELSE here!
FROM
  ...
GROUP BY
  x, y

这种形式的查询适用于 CASE WHEN 选择字符串、日期或其他无法求和的东西的情况（它适用于像你这样的情况，如果它只是一列空值中的一个数值） - 总而言之，它比使用更灵活SUM(CASE WHEN ... THEN ... ELSE 0 END)

如果您希望 SE_PCNT_Generated、SE_PCNT_At_Post 和 SE_PCNT_Daily 的值明智地存储并明智地报告日期，请使用：

                            max(CASE WHEN REPORT_TYPE = 'G' THEN SE_PCNT ELSE 0 END )AS SE_PCNT_Generated,
                            max(CASE WHEN REPORT_TYPE = 'A' THEN SE_PCNT ELSE 0 END )AS SE_PCNT_At_Post,
                            max(CASE WHEN REPORT_TYPE = 'D' THEN SE_PCNT ELSE 0 END )AS SE_PCNT_Daily
                FROM (
                
                SELECT  STORE_NUM,
