1表绿色DAO的多个ToMany

Question

>我有 2 个这样的模型：

@Entity
public class Book {
    @Id
    Long _id;
    String name;
    @ToMany(referencedJoinProperty = "bookId")
    List<Chapter> chapters1;
    @ToMany(referencedJoinProperty = "bookId")
    List<Chapter> chapters2;
}

@Entity
public class Chapter {
    @Id
    Long _id;
    String name;
    int type;
    long bookId;
    @ToOne(joinProperty = "bookId")
    Book book;
}

章节类型1和2有2种类型，

目前，当我得到章节1时，greenDAO返回所有类型1和2，如何在类书中只获得类型1或2？

Answer 1

尝试执行此查询

Select from Chapter where type = [1 or 2]
