Mysql 从post方法插入多个数组

我试图从postman获取post数据，它是多个数据数组，但似乎无法将它们放入数据库，如果我在post上对数组进行硬编码，它将进入数据库，但不是动态的

index.js

/* POST home page. */
router.post('/', function (req, res) {
    const sql = require('../models/db.js');

    let data = req.param('data');
    console.log(data);

    const sqlstatement = "INSERT INTO Sales (user_id, type, amount) VALUES (?)";

    sql.query(sqlstatement, [data], function (err, res) {

        if(err) {
            console.log("error: ", err);
        }
        else{
            console.log(res.insertId);
        }
    });

    res.send(data);

});

db.js

邮递员数据

[{"key":"data","value":"[[111, 'net', 1234],[111, 'gross', 1234]]\n","description":"","type":"text","enabled":true}]

控制台错误

code: 'ER_BAD_FIELD_ERROR',
  errno: 1054,
  sqlMessage:
   "Unknown column '[[111, 'net', 1234],[111, 'gross', 1234]]' in 'field list'",
  sqlState: '42S22',
  index: 0,
  sql:
   "INSERT INTO Sales (user_id, type, amount) VALUES (`[[111, 'net', 1234],[111, 'gross', 1234]]`)" }

您必须为每一列打上问号。

准备适当的SQL语句

INSERT INTO Sales (user_id, type, amount) VALUES (111, 'net', 1234),(111, 'gross', 1234);

您是否尝试在DB上手动运行生成的查询？我认为这可能会解决您的问题

const sqlstatement = "INSERT INTO Sales (user_id, type, amount) VALUES (?,?,?)"

INSERT INTO Sales (user_id, type, amount) VALUES (111, 'net', 1234),(111, 'gross', 1234);
