json - 更新 Mysql/Mariadb 中的嵌套 Json

Question

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

如何从对象更新Employee值。Man我想要类似于下面的mysql查询的东西。

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

MariaDB [**********]> SELECT VERSION();

Answer 1

首先，keys通过为每个添加引号来修复 JSON 列中的内容，并values为一些以零开头并继续使用其他数字的部分添加引号。

然后申请：

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