IN在領域運作

Question

我總共有三個班級來管理經銷商選定的產品數據。擴展RealmObject

1) Dealers 
    DealerId 
    DealerName 

2) Products 
    ProductId 
    ProductName 
3) DealerProduct (contains the mapping between Dealers's selected product) 
    DealerId 
    ProudctId 

類現在我想用領域

select * from Products where productId IN ('P101','P102'); 

火查詢是否有辦法在境界火IN操作

Answer 1

您可以使用RealmQuery.or()

RealmResults<Products> products = realm.where(Products.class) 
      .equalTo("productId", "P101") 
      .or().equalTo("productId", "P102") 
      .findAll();
