Node.js / MySQL：在node.js的错误日志中打印实际查询

根据docs，您可以

query.sql

var post  = {id: 1, title: 'Hello MySQL'};var query = connection.query('INSERT INTO posts SET ?', post, function(err, result) {  // Neat!});console.log(query.sql); // INSERT INTO posts SET `id` = 1, `title` = 'Hello MySQL'

在这种情况下，

connection.query(command, function (err, rows) {    if (err) {        console.log('this.sql', this.sql); //command/query        console.log(command);        console.log("ERROR");        console.log(err);        return;    }    console.log("good");});
