更新 Mysql/Mariadb 中嵌套的 Json

Question

{
  "people": {
    "Man": {
      "Employee": "50",
      "Student": "91",
      "Artist": "80",
      "Clark": "50"
    },
    "Woman": {
      "Employee": "21",
      "Student": "01",
      "Artist": "00",
      "k3": "30",
      "Clark": "68"
    }
  }
}

如何从 Man 对象更新 Employee 值。我想要类似于下面 mysql 查询的内容。

UPDATE TABLE 
   SET Column = JSON_SET(Column, '$.people.Man.Employee', '51') 
  WHERE Id=1234567890;

首先，修复 JSON 列中的 keys，为每个列添加引号，values 为一些以零开头并继续其他数字的引号添加引号。

然后申请：

UPDATE tab
   SET Col = JSON_SET(
       Col,
       "$.people.Man.Employee", "50",
       "$.people.Man.Employee", "51"
       )
 WHERE ID = 1234567890;
