Aggregate function or the GROUP BY clause in SQL Server

Question

I want to get the sum per day by its specified date, show the sum and the tenant name on it. It should be like this. Does it have any possible way to construct it right??

tenant_id tenant_name  Total Amount
-----------------------------------
  123      SAMPLE         37100

Answer 1

use both column in group by like below

 group by tenant_id ,tenant_name

so your query will be

select   s.tenant_id ,i.tenant_name,
   sum(s.amount) as total
  from sales_data s left join
      Tenant_info i 
       on s.tenant_id=i.tenant_id
  group by s.tenant_id ,i.tenant_name

Note: maximum db throwns error if you have not put the selection column in group by in times of using aggregate function
