Rank（）为什么不能按照它的方式工作？

Question

这是我的表中的数据： -

Insert Into tblProduct (ProductId,ProductName,Description,Category) Values (1,'Cinthol','cosmetic soap','soap'); 
Insert Into tblProduct (ProductId,ProductName,Description,Category) Values (1,'Cinthol','cosmetic soap','soap'); 
Insert Into tblProduct (ProductId,ProductName,Description,Category) Values (1,'Cinthol','cosmetic soap','soap'); 
Insert Into tblProduct (ProductId,ProductName,Description,Category) Values (1,'Lux','cosmetic soap','soap'); 
Insert Into tblProduct (ProductId,ProductName,Description,Category) Values (1,'Crowning Glory','cosmetic soap','soap'); 
Insert Into tblProduct (ProductId,ProductName,Description,Category) Values (2,'Cinthol','nice soap','soap'); 
Insert Into tblProduct (ProductId,ProductName,Description,Category) Values (3,'Lux','nice soap','soap'); 
Insert Into tblProduct (ProductId,ProductName,Description,Category) Values (3,'Lux','nice soap','soap'); 

当我发出这个查询： -

Select ProductId, 
     ProductName, 
     Description, 
     Category, 
     RANK() Over (partition by ProductId Order By ProductId) As Rank 
From tblProduct; 

所有我能看到的是1st等级每排。其他所有行列在哪里？行与productid 2应该有排名6，因为我不使用DENSE_RANK()。为什么查询不起作用？

Answer 1

您正在通过ProductId进行分区 - 这意味着每个“分区”将从1开始RANKing。尝试删除PARTITION BY ProductId。
