javascript - 尝试使用 Express 将数据插入 MySql 数据库时出错

Question

我正在尝试对数据库运行插入查询，但出现以下错误:

code: 'ER_PARSE_ERROR',

我的代码是:

...
let sqlData = JSON.parse(req.body.jsonPost);
  //console.log(sqlData)
  var result = [];
  var date = "";
  for (let i = 0; i < sqlData.length; i++) {
    let toPush = [];
    toPush.push(sqlData[i]["currentDate"]);
    date = sqlData[i]["currentDate"];
    toPush.push(sqlData[i]["receipts"]);
    toPush.push(sqlData[i]["qty"]);
    toPush.push(sqlData[i]["pounds"]);
    toPush.push(sqlData[i]["ppu"]);
    toPush.push(sqlData[i]["gross_receipts"]);
    toPush.push(sqlData[i]["average"]);
    //toPush.push(sqlData[i]["houseNumber"])
    toPush.push(req.params.id.toString())

    result.push(toPush);
  }
  queryString = 'DELETE FROM house_totals WHERE currentDate = ? AND house_number = ?; INSERT INTO house_totals (`currentDate`, `receipts`, `qty`, `pounds`, `ppu`, `gross_receipts`, `average`, `house_number`) Values ?;'
  getConnection().query(queryString, [date.toString(), req.params.id.toString(), result], function (err, results, fields) {
...

我已经在 MySql 工作台中运行了该命令，如果我删除斜杠，它执行得很好，但错误在我的 Express 应用程序中仍然存在

我尝试了多种删除正斜杠的方法，但即使没有斜杠，错误仍然存​​在，所以此时我已经没有想法了。任何帮助将不胜感激。

作为单独的查询运行删除和插入。如果它们需要原子性，请将它们放在同一个事务中。 – 丹布莱克
