以有效方式在postgresql、选项数组或对象中插入jsonb数据

Question

我有这个更新，我已经阅读postgresql留档，但不清楚如何插入数据，一些教程选项：

1.with '{}'
2.with {}
3.with '[]'  <-- array of objects

大多数人不“使用”：：jsonb“like”显示在：

https://www.postgresql.org/docs/9.4/static/datatype-json.html

这是我的代码：

 UPDATE customer set phones ='{  {"type": "mobile", "phone": "001001"} ,
{"type": "fix", "phone": "002002"}  }'::jsonb  
  where id ='4ca27243-6a55-4855-b0e6-d6e1d957f289';

我得到了这个错误：

ERROR:  invalid input syntax for type json
LINE 1: UPDATE customer set phones ='{  {"type": "mobile", "phone": ...
                                    ^
DETAIL:  Expected string or "}", but found "{".
CONTEXT:  JSON data, line 1: {  {...
SQL state: 22P02
Character: 29

我只需要记录一个手机，需要附上一个大名对象，比如？我的意思是对于javascript，对象数组不是对象，但我不知道这是否在postresql的jsonb中被接受

{phones:[{“type”：“mobile”，“phone”：“001001”}，{“type”：“fix”，“phone”：“002002”}]}

Answer 1

“{}”是postgres中的数组类型。如果使用jsonb，请对数组使用常规的“[]”：

so=# select jsonb_pretty('{"phones":[ {"type": "mobile", "phone": "001001"} , {"type": "fix", "phone": "002002"} ] }');
jsonb_pretty
{
    "phones": [
        {
            "type": "mobile",
            "phone": "001001"
        },
        {
            "type": "fix",
            "phone": "002002"
        }
    ]
}
(1 row)

或：

so=# select jsonb_pretty('[ {"type": "mobile", "phone": "001001"} , {"type": "fix", "phone": "002002"} ]');
jsonb_pretty
[
    {
        "type": "mobile",
        "phone": "001001"
    },
    {
        "type": "fix",
        "phone": "002002"
    }
]
(1 row)

Answer 2

CREATE TABLE customer {
  contact JSONB
}

update customer
set contact = '{ "phones":[ {"type": "mobile", "phone": "001001"} , {"type": "fix", "phone": "002002"} ] }'
where id = '4ca27243-6a55-4855-b0e6-d6e1d957f289';

CREATE TABLE customer {
  phones JSONB
}

update customer
set phones = '[ {"type": "mobile", "phone": "001001"} , {"type": "fix", "phone": "002002"} ]'
where id = '4ca27243-6a55-4855-b0e6-d6e1d957f289';
