I am using from architect component and I need to set a lot of query on bellow values. How to create relation between bellow entities for query? in normal mode I can't access to nested objects.
For example I need to @Query("SELECT * FROM Content Where parent_id = 100") and other queries or I need to values that the name is JIM... but in normal mode I can't access to nested objects.
@Entity(tableName = "tblCourseContentList")
public class CourseContentListModel {
@PrimaryKey(autoGenerate = true)
private long id_courseContentList;
@SerializedName("status")
@Expose
private String status;
@SerializedName("0")
@Expose
@Embedded
private _0 _0 = null;
// --- CONSTRUCTORS ---
@Ignore
public CourseContentListModel() {
}
public CourseContentListModel(long id_courseContentList,
String status,
_0 _0) {
this.id_courseContentList = id_courseContentList;
this.status = status;
this._0 = _0;
}
//region --- GETTER ---
