Is it possible to construct a query in which I can retrieve week day name from a date into a separate column or variable?
I know I can very easily do this on .NET side but would like it to be in the query.

It is possible you will need to build your query which returns day names and then join to your result on day number
int[] dayNum={1,2,3,4,5,6,7};
var result = from d in dayNum
let dayOfWeek= (d == 1 ? "Monday" :
d==2 ? "Tuesday" :
d==3 ? "Wednesday" :
d==4 ? "Thursday" :
d==5 ? "Friday" :
d==6 ? "Saturday" :
d==7 ? "Sunday":"")
let dn = d
group d by new {dayOfWeek, dn} into dw
select new { dw.Key.dayOfWeek, dw.Key.dn};
The result of this will be
You can also use SqlFunctions...
Of course, this only works when using a SQL Server. Methods that are cross-database, would be to use EntityFunctions.DateDiff with a known date to get the number of days between whatever and a known prior sunday, then modulus 7, then convert to a string.
