JSON Objects
A JSON object is a comma separated list of key:value pairs surrounded by braces {}.
A key must be a double-quoted string. A value can be any JSON value including a JSON object or JSON array. It cannot be blank.
Whitespace is ignored in a JSON object string except for whitespace within the double quotes of a string.
Example:
{ "type": "Feature",
    "geometry": {
          "type": "Point",
          "coordinates": [0, 90] },
          "properties": { "name": "North Pole" }
     }
}
Keys in a JSON object do not have to be unique. During key retrieval, however, only the first value is returned.
In addition, JSON objects are considered an unordered set of key:value pairs, so subsequent key retrievals may return the “other” duplicate key.
You can create a JSON object from table data using the JSON_OBJECT constructor, as described in JSON_OBJECT.
