Question

我从早上开始非常困难，有人可以帮助我我有一个没有返回任何值的SQL数据适配器。在顶部的同一页面中我有一个SQldataadaptor工作正常。我不知道该怎么办。查询在服务器中正常工作。我正在使用vs10和sqlserver 2008 ..

我还尝试删除它仍然无效的参数'。我的行数始终为零

这是我的代码

       doc = dr["DrName"].ToString();
           sql1 = "select w.Day, w.Start,[End] from WeeklyScheduleDays w where w.Start is not null and w.Day = @day1 and  WeeklyScheduleID = (select WeeklyScheduleID from DoctorsBusinessHours db inner join drmast m  on m.DoctorId = db.DcotorID where m.DrName = '@drname2') order by Start ";


           SqlCommand m1 = new SqlCommand(sql1,myConnection);
           m1.Parameters.AddWithValue("@day1", i);
            m1.Parameters.AddWithValue("@drname2", doc);

             SqlDataAdapter ad = new SqlDataAdapter(m1);
            DataTable t1 = new DataTable();
             ad.Fill(t1);


           rowcount = t1.Rows.Count;

提前致谢

Answer 1

将where m.DrName = '@drname2'替换为where m.DrName = @drname2

Dataadaptor不返回任何值，也不会返回任何异常
