SOD框架的Model、连接数据库及增删改查

  PDF.NET SOD连接数据库只支持明文写在config文件的：

<configuration>
  <connectionStrings>
    <add name="StudentDB" connectionString="Data Source=.;Initial Catalog=StudentDB;Integrated Security=False;User ID=sa;Password=123;max pool size=1" providerName="System.Data.SqlClient" />
  </connectionStrings>
</configuration>

可以研究下这个：https://blog.csdn.net/qqcxw/article/details/51927469

//查询：
UserTab user = new  UserTab(){UserID = 1};
OQL q=OQL.From(User).select().Where(User.UserID).END;
UserTab dbUser = EntityQuery<UserTab>.QueryObject(q);
//查询2：
 List<Stu> LStu = new List<Stu>();
            var StuList = OQL.FromObject<Stu>().Select().Where((x, c) => x.Comparer(c.IsDelete, "=", false)).END.ToList();

//删除：相当于：Delete from [UserTab] where [UserID] = 2
UserTab user = new UserTab();
OQL deleteQ = OQL.From(user).Delete().Where(cmp => cmp.Comparer(user.UserID,OQLCompare.comUserTab>.Instance.ExecuteOql(deleteQ);

//更新整个实体：
UserTab user = new UserTab(){UserID = 1 ,UserName = "张三",pwd="XXX"};
//更新某个字段：相当于：update [UserTab] set [UserName] = "李四",[pwd] = "XXX" where [UserID] = 1
UserTab user = new  UserTab(){UserID = 1,UserName="李四",pwd="XXX"};
OQL updateQ = OQL.From(user).Update(user.UserName).END;
EntityQuery<UserTab>.Instance.ExecuteOql(updateQ);//只更新姓名

//插入全部数据：
UserTab user = new UserTab(){UserName = "张三",pwd="XXX"};
EntityQuery<UserTab>.Instance.Insert(user);
//插入部分数据：
UserTab user = new UserTab(){UserName = "张三",pwd="XXX"};
OQL insertQ = OQL.From(user).Insert(user.UserName).END;
EntityQuery<UserTab>.Instance.ExecuteOql(insertQ);
