SQL

var reportsByAuth =
           from d in
               (from c in rbaDC.ReportDetails
                from d in rbaDC.ReportAuthorizations
                where c.id == (d.reportid) && (d.role == "admin" || d.loginid == "a")
                select new { c.id, c.displayname, c.name })
           join ef in rbaDC.auditreports
               on d.id equals ef.reportid
           select new { d.id,d.displayname,d.name,ef.favtcol };

Can anybody please tell me if this answer is valid?
