如何使用n1ql查詢

Question

{ 
"name":"nick", 
"emailId":"nick123@gmail.com", 
"subjects" : [{ 
    "name":"SOA", 
    "tutor":"roshan", 
    "classes" : "12" 
}, 
{ 
    "name":"UNIX", 
    "tutor":"mathew", 
    "classes" : "9" 
} 
], 
"id" : "12345" 
} 

我想補充另一組使用更新查詢主題，以更新couchbase陣列。 我厭倦了通過看到一些網站，但它顯示錯誤，我無法理解的一些查詢。 如果您提供建議並感謝您的幫助，它會更有幫助。 我累是查詢： - [更新studapp ARRAY a.name = 「網絡」，a.tutor = 「莎琳」，a.classes = 「8」 FOR IN一個受試者END 其中id =「12345 「;]

update `studapp` 
SET subjects= ARRAY_APPEND(subjects, { "name":"SE", 
    "tutor":"Mani", 
    "classes" : "7" }) 
where id = '12345';
