javascript - Node JS MySQL插入查询多变量ER_PARSE_ERROR

问题描述

我创建了一个 webhook 来使用 Node.JS 在此处接收一些数据。我正在使用 MySQL 存储我的数据，到目前为止，服务器能够连接到数据库，接收客户端数据，并在接收到数据时做出适当的响应。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，例如不将列名包裹在单引号中，不包裹表名，以及在查询字符串中的每个部分在双引号和单引号之间切换。

任何建议，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：

解决方案

我会做这样的事情。

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}" ...)`;
