title: SQLiteException no such column while compiling
body: <pre><code>exams = new Select().from(DataExam.class).groupBy("LessonName").where("Favourite = " + 1).execute();
  </code></pre>
  
  <p>I'm use this code to get data from sql db, but always i get this error</p>
  
  <blockquote>
    <p>SQLiteException: no such column: Favourite (code 1): , while
    compiling: SELECT * FROM DataExam WHERE Favourite = 1 GROUP BY
    LessonName</p>
  </blockquote>
  
  <p>it's <strong>DataExam.class</strong></p>
  
  <pre><code>@Table(name = "DataExam")
  public class DataExam extends Model implements Serializable {
  
  @Column(name = "Id")
  String Id;
  
  @Column(name = "ExamId")
  String ExamId;
  
  @Column(name = "CategorieName")
  String CategorieName;
  
  @Column(name = "CategorieText")
  String CategorieText;
  
  @Column(name = "CategoriePicture")
  String CategoriePicture;
  
  @Column(name = "CategoriePictureThumb")
  String CategoriePictureThumb;
  
  @Column(name = "CategorieSortOrder")
  public String CategorieSortOrder;
  
  @Column(name = "Favourite")
  public Boolean Favourite;
  
  @Column(name = "LessonName")
  public String LessonName;
  </code></pre>
