如何从电报机器人将数据插入数据库？

Question

我正在写一个电报机器人。 测试需要这个机器人。 该机器人的主要任务是将用户响应写入数据库。 我需要将用户的消息写入数据库。 由于发生错误，我目前无法编写消息。 我在哪里 go 错了？ 请帮助解决这个问题。

      if (msg.text === '/start') {
        await bot.sendMessage(msg.chat.id, "message", {
          reply_markup: {
            keyboard: [
              ['Start the test']
            ]
          }
        })
      }
      else if (msg.text === 'Start the test') {
        await bot.sendMessage(msg.chat.id, "Please enter your name")      
          bot.on('message', async msg => {
            const name = msg.text
            const insert = `INSERT INTO User (username) VALUE ('${name}')`
            await sequelize.query(insert)
          })
      }

错误信息：

Executing (default): INSERT INTO User (username) VALUE ('name')
node:internal/process/promises:246
          triggerUncaughtException(err, true /* fromPromise */);
          ^

您必须从以下位置更改您的查询：

INSERT INTO User (username) VALUE ('text')

至

INSERT INTO User (username) VALUES ('text')
