ExecuteStoreQuery for custom columns

I am trying to run a custom query and I am using the Entity framework, I have tried this

string query = @"SELECT dm.DistrictName,sm.SchoolName,u.UserId,u.FirstName,u.LastName, sa.StudentId, sa.ReadingLevel
                 FROM  studentassessment sa
                 INNER JOIN assessmentmaster am ON sa.AssessmentId = am.AssessmentId
                 INNER JOIN studentclass sc ON sa.StudentId = sc.StudentId
                 INNER JOIN USER u ON sc.TeacherId = u.UserId
                 INNER JOIN schoolmaster sm ON u.SchoolCode = sm.SchoolCode
                 INNER JOIN  districtmaster dm ON sm.DistrictId = dm.DistrictId
                 WHERE u.RoleId = 5 && sa.GradeId = " + objParam.Grade + " && sa.AssessmentPeriodId = " + x.AssessmentPeriodId + " && dm.DistrictId = " + districtCode + " && am.DRAType = '" + objParam.LanguageType + "' && am.AssessmentTypeId = 1";



var dt = db.ExecuteStoreQuery<List<object>>(query).FirstOrDefault();

But it didn't work out.

Is there a way to get results from ExecuteStoreQuery

in a struct that is not associated with any type of object?

Not. EF ExecuteStoreQuery

requires a data type (class) with properties with the same names as the columns in your query result set. If you want to execute a query without creating a custom type for your result set, you need to use ADO.NET and SqlDataReader

.
