我收到LINQ查询标题中显示的错误,该查询包括来自两个不同edmx文件的两个表.这是查询:

var query = (from a in db1.Table1
           join b in db1.Table2 on a.Id equals b.Id
           orderby a.Status
           where b.Id == 1 && a.Status == "new"
           select new
           {
               Id = a.Id,
               CompanyId = (from c in db2.Company
                            where s.Id == a.Id
                            select
                            new { c.CompanyId })
           });

db1并且db2是与两个不同的edmx文件关联的上下文.我怎样才能克服这个错误？
