我在一个api响应中得到一个大的json数据。我正在尝试将这个json响应存储在本地mysql表中。但无法存储完整的json响应。请查找以下json信息。

api json响应示例：

{
    "responseCode": 200,
    "date": "2020-06-03",
    "message": "Success",
    "couponDetails": {

    }
}

在我的本地数据库表中，我只能插入以下信息，但不完整：

{
    "responseCode": 200,
    "date": "2020-06-03",
    "message": "Success",
    "couponDetails": {
        "total": 14949,
        "codes": "35033769,35441136,35803675,34407176,34717909,34950692,35059148,35452352,35688911,35904465,35904658,35904753,35904824,35904942,35905306,

mysql表结构：

CREATE TABLE `bookdata_codeinfo_history` (
  `generated_date` date DEFAULT NULL,
  `book_code` longtext,
  `service` varchar(45) DEFAULT NULL
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

我想把json存储在“book\u code”字段中，但存储的信息很少。我使用的是mysql-5.7.13版本。请告诉我如何解决这个问题
