moongose查詢的WHERE和OR NOT

Question

我無法放在一起有效的查詢，或至少查詢，我得到正確的數據回來了貓鼬。在SQL它會是這樣

SELECT * FROM table WHERE id = 123 AND deleted_by != 1 OR deleted_by != -1; 

Answer 1

我最終解決它這個樣子。

conversationModel.find({ 
    user_to_user_from: 123, 
    deleted_by: { 
     $nin: [1, '-1'], 
    } 
}); 

Answer 2

可以使用的$or和$ne組合像下面

db.collection.find({ id: 123, $or: [{ deleted_by: { $ne: 1 } }, { deleted_by: { $ne: -1 } }]}); 

或$nor

db.collection.find({ id: 123, $nor: [{ deleted_by: 1 }, { deleted_by: -1 }]});
