我是很新的n1ql查詢，會有人請幫我找到插入溶液對象/更新數組對象用。示例1將數據插入JSON，示例2正在將數據更新爲示例1，並遵循... 1.請幫助獲取滿足上述示例的n1ql查詢。 2.如何在文檔

Answer 1

1）中產生一個UUID到id字段追加如果元件陣列中的已存在

INSERT INTO default VALUES ("k01", { "details": [ { "id": 1234, "city": "Medway", "country": "United Kingdom", "name": "Medway Youth Hostel", "url": "http://www.yha.org.uk" }] }); 

UPDATE default AS d SET e.contact = [ { "email": "hari34@gmail.com", "phone": 6789435634 } ] 
          FOR e IN d.details WHEN e.id = 1234 END 
WHERE META().id = "k01"; 

UPDATE default AS d SET e.contact = ARRAY_APPEND(e.contact,{ "email": "sri123@gmail.com", "phone": 9876655555 }) 
          FOR e IN d.details WHEN e.id = 1234 END 
WHERE META().id = "k01"; 

UPDATE default AS d SET d.details = ARRAY_APPEND(d.details,{ "id": 3456, "city": "Texas", "country": "USA", "name": "Texas Youth Hostel", "url": "http://www.yha.org.uk", "contact": [ { "email": "ram123@gmail.com", "phone": 876543219 } ] }) 
WHERE META().id = "k01"; 

SELECT * from default USE KEYS["k01"]; 

2）使用UUID（）函數狀陣列永遠不會檢查下面

INSERT INTO default VALUES ("k01", { "details": [ { "id": UUID(), "city": "Medway", "country": "United Kingdom", "name": "Medway Youth Hostel", "url": "http://www.yha.org.uk" }] });
