如何将使用动态查询的相关实体包括在内
原标题:How to include related Entities using dynamic queries

我在申请中从搜索表中拿到价值观,以建立一个动态的质问:

string queryString = @"SELECT VALUE USERS FROM ProjectDBEntities.Users AS Users 
WHERE ";

数据库中有两个表格:UsersPhoto,表光有栏目UserId链接到用户表。 用户和照片之间存在一种至多种关系。

在通过形式价值和添加系统进行某些重复之后。 数据-目标值,我最后提出以下询问:

SELECT VALUE USERS FROM ProjectDBEntities.Users AS Users 
WHERE Users.CountryId = 2

然后,我有这个法典:

System.Data.Objects.ObjectQuery<Users> usersQuery =
                new System.Data.Objects.ObjectQuery<Users>(queryString, _db);

用户名标物不含每个用户的图像数据。 在我的看法中,我可以通过用户加以利用。 图像,但图像数总是零。 我是否必须列入或附上图像数据? 如何?

最佳回答

仅添加一个<代码>。

System.Data.Objects.ObjectQuery<Users> usersQuery =
            new System.Data.Objects.ObjectQuery<Users>(queryString, _db).Include("Image");
