Question

SELECT [order id], 
       pickingdate 
FROM   td_order1 
WHERE  sku = xyz 
GROUP  BY pickingdate, 
          [order id] 
HAVING pickingdate >= Min(pickingdate) 
       AND pickingdate <= Max(pickingdate) 
ORDER  BY pickingdate

此查询有什么问题吗？

Answer 1

查询的问题是您正在使用having中未聚合的列。我的建议是使用窗口功能：

SELECT o.*
FROM (SELECT o.*,
             MIN(pickingdate) OVER (PARTITION BY sku) as min_pd,
             MAX(pickingdate) OVER (PARTITION BY sku) as max_pd
      FROM td_order1 o
      WHERE sku = xyz 
     ) o
WHERE pickingdate > min_pd and pickingdate < max_pd
ORDER BY pickingdate;

Answer 2

将条件修改为：

pickingdate < Max(pickingdate)

排除结束日期

SQL获取包括开始日期和结束日期之间的日期
