Question

我有DB，由2个表组成：

**Job**
     job_id (int, primary key),
     job_nm (nchar(50))

**Employee**
     empl_id (int, primary key)
     job_id (int, forein key) (one-to-many)
     first_name (nchar(50))
     last_name (nchar(50))
     salary (float)

我逐页输出表格（每页5行）。它意识到：

ViewBag.Tab = (from employee in db.Employees 
               join job in db.Jobs on employee.job_id equals job.job_id 
               where job.job_nm == sel1 
               orderby employee.salary 
               select employee
              ).Skip(pageSize * pageNum)
               .Take(pageSize)
               .ToList();

但是我没有通过＆＃34; salary＆＃34; -field list。

我试过这段代码：

ViewBag.Tab = (from employee in db.Employees 
               join job in db.Jobs 
               on employee.job_id equals job.job_id 
               where job.job_nm == sel1 
               orderby employee.salary 
               select employee
              ).Skip(pageSize * pageNum)
               .Take(pageSize)
               .ToList()
               .OrderBy(s => s.salary);

但它没有结果。

我做错了什么？

Answer 1

OrderBy需要先于Skip和Take。另外，你只是要订购你的小结果集。

尝试：

ViewBag.Tab = (from employee in db.Employees 
               join job in db.Jobs 
               on employee.job_id equals job.job_id 
               where job.job_nm == sel1 
               orderby employee.salary 
               select employee
              ).OrderBy(s => s.salary)
               .Skip(pageSize * pageNum)
               .Take(pageSize)
               .ToList();

不按属性排序
