sql - Get Group By Column in result set without using CTE

Question

Here is the following query

select CAST(DepositeDate AS DATE) as DepositeDate,SUM(TotalAmount) as Amount
from Payment
group by DepositeDate 

I am getting the following result.

DepositeDate | Amount | 
2021-04-30   | 50     | 
2021-04-30   | 50     | 
2021-04-26   | 75     | 
2021-04-11   | 30     | 
2021-04-11   | 30     | 

But I need the following result

DepositeDate | Amount | 
2021-04-30   | 100    | 
2021-04-26   | 75     | 
2021-04-11   | 60     |  

Is this possible without using CTE?

Answer 1

Apparently, your DepositeDate column has a time component. Repeat the expression in the GROUP BY:

select CAST(DepositeDate AS DATE) as DepositeDate,
       SUM(TotalAmount) as Amount
from Payment
group by CAST(DepositeDate AS DATE) 
order by CAST(DepositeDate AS DATE);

SQL Server does not recognize aliases in the GROUP BY. So DepositeDate is always going to refer to a column defined in the FROM clause and not the expression in the select.
