Here is my Service
table's columns:
id
serverPlace
count
Here is a SQL query which I need to convert it into Linq:
SELECT Service.id,
Service.serverPlace,
sum(Service.count * 12 + MONTH(getdate())) AS sum
FROM Service
GROUP BY Service.id, Service.serverPlace;
I do not know how to convert and implement sum
section with Linq.
It should look like this:
var month = DateTime.Now.Month;
var result = await dbContext.Services.GroupBy(r=> new { r.Id, r.ServerPlace })
.Select(r=> new {
r.Key.Id,
r.Key.ServerPlace,
Sum = r.Sum(q=> q.Count*12 + month)
}).ToArrayAsync();
