Question

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

我想使用更新查询添加另一组主题。我厌倦了看一些网站，但它显示错误，我无法理解。如果您给出建议并感谢您的帮助，将会更有帮助。我累的查询是： - [更新studapp ARRAY a.name =“networks”，a.tutor =“shalin”，a.classes =“8” 对于IN科目END 其中id ='12345';]

Answer 1

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

我得到了我需要的结果（为现有数组添加了一组新值）
