 select Top 3 * from t1 group by sale_Amnt 

|Id|product_name|product_group    |sale_Amnt(INR)
------------------------------------------------
 1|  p1       |   Cosmetic       |4485
 2|  p2       |   Cosmetic       |8525
 3|  p3       |   Health         |12589
 4|  p4       |   Health         |8525
 5|  p5       |   Home Appliances|9858
 6|  p6       |   Home Appliances|12589

预期输出

|Id|product_name|product_group    |sale_Amnt(INR)
------------------------------------------------
 2|  p2       |   Cosmetic       |8525
 4|  p4       |   Health         |8525`

Answer 1

建议的副本是对问题的误解。这个问题似乎是在寻找总体上第三高的价值，但要考虑重复数据。

您可以在SQL Server中使用offset / fetch获取第三行：

select t.*
from t
where t.sale_amount = (select t2.sale_amount
                       from t t2
                       group by t2.sale_amount
                       order by t2.sale_amount desc
                       offset 2 fetch first 1 row only
                      );

在MySQL中，那将是：

select t.*
from t
where t.sale_amount = (select t2.sale_amount
                       from t t2
                       group by t2.sale_amount
                       order by t2.sale_amount desc
                       limit 1 offset 2
                      );
