javascript - Node JS MySQL 插入多变量查询 ER_PARSE_ERROR

Question

我创建了一个 webhook 来使用 Node.JS 接收一些数据。我使用 MySQL 存储数据，到目前为止，服务器能够连接到数据库，接收客户端数据，并在接收数据后做出适当的响应。我只是在格式化 MySQL 的查询字符串时遇到问题。

我尝试了各种引号配置，例如不将列名称括在单引号中、不将表名称括起来以及在查询字符串中的每个部分上在双引号和单引号之间切换。

如有任何建议，我们将不胜感激!谢谢!

我的查询:

var sql = "INSERT INTO 'cms'('ts', 'orgid', 'orgname', 'deviceid', 'devicename', 'event', 'setid', 'setname', 'viewid', 'viewname', 'duration', 'hotspotid', 'hotspotname', 'playlistid', 'playlistname', 'playlisttype', 'playlistassetid', 'playlisttitle') VALUES ("+timestamp+", "+orgid+", "+orgname+", "+deviceid+", "+devicename+", "+eventname+", "+setid+", "+setname+", "+viewid+", "+viewname+", "+duration+", "+hotspotid+", "+hotspotname+", "+playlistid+", "+playlistname+", "+playlisttype+", "+playlistassetid+", "+playlisttitle+")";
                            con.query(sql, function (err, result) { //Queries String with MySQL connection variable con
                                    if (err) throw err;
                                    var date = new Date();
                                    var currHour = date.getHours();
                                    console.log("Record Inserted at " + currHour); //Logs time of db insertion on console
                            });

这也是错误:

我猜问题出在这段代码上:

VALUES ("+timestamp.toString()+"

你能尝试转义那些双引号字符吗？
